Compressive Strength test was performed out on hardened 150mm concrete cubes after 3, 7, & 28 days curing in water. The output of the research work was a highly workable concrete which could be used for densely reinforced sections of Mivan shuttering.Item Experimental investigation of pervious concrete using fly ash and nano silica(AIKTC, 2020-05) Patil, Dada S.; Sarzeel, Hussain (16CE28); Pal, Rajesh (16CE30); Shaikh, Basit (16CE40); Shaikh, Hamza (16DCE83)Pervious concrete (no fines concrete) is a concrete containing little or no fine aggregate; it consists of coarse aggregate and cement paste. It seems pervious concrete would be a natural choice for use in structural applications in this age of green building. It consumes less raw materials than normal concrete (no sand), it provides superior insulation values when used in walls, and through the direct drainage of rainwater, it helps recharge groundwater in pavement applications. The first pervious concrete was used in Europe and the united kingdom since 1930s for the building of single and multi storeyed houses, but had found little acceptance in rest of the world. Even though it is not yet widely used, pervious concrete is generally used for light duty applications, such as residential streets, parking lots, driveways, sidewalks, channel lining, retaining walls and sound walls. The aim of this study is to investigate compressive strength of pervious concrete by eliminating the fine aggregate; additionally investigate infiltration rate of pervious concrete. Referring to the available literature, it was attempted to mix cement & coarse aggregates at two different water-cement ratios. As the pervious concrete finds its wide application in parking areas, footpaths, garden paving, etc., higher compressive strength was not an objective. The focus of the current work was on providing adequate permeability to the concrete mass so that the water can easily pass through it. The slump required for the pavement work is exceptionally low. Therefore, production of zero slump concrete was aimed at. The wide use of the pervious concrete for the various applications mentioned above is the need of the hour. The water infiltrated through the pervious concrete would also contribute towards enhancing the ground water level i.e. it would facilitate ground water recharge.Item Experimental investigation on characteristic properties of light weight concrete(AIKTC, 2020-05) Patil, Dada S.; Dhanwanti, Baikar (16CE02); Shetty, Vishwajeet (16CE44); Siddique, Zakir (16CE45); Malve, Akash (17DCE58)Light weight concrete is a relatively new concept. This concrete can be used for heat insulation on roofs, construction of panel walls and partition walls in framed structures ,casting structural steel to protect it against fire and corrosion , as covering for architectural purposes , surface rendered for external walls of small houses etc. Aggregates provide volume at low cost , comprising of 66 to 78 percentage of entire concrete. With increasing concern for the over exploitation of the natural aggregates hence the environment, the waste materials obtained from different industries and agricultural activities also household activities which are identified to be potential aggregates are a new source of obtaining building materials for construction industry. This experimental investigation was carried out to determine whether coconut shells can be used as aggregates in concrete . Utilising coconut shells as aggregate in concrete not only solves the problem of solid waste management and disposal but also helps in reducing the tremendous pressure on the environment due to ever increasing demand of aggregates. This study shows a comparison between conventional concrete properties and the concrete prepared by using coconut shells as light weight aggregates. Tests results which were compared are slump cone test, compressive strength test and split tensile test. Test age for concrete elements was kept 7days, 21 days and 28 days respectively.Item Experimental investigtion on characteristic properties of previous concrete(AIKTC, 2018-05) Patil, Dada S.; Mujawar, Ayub(12CE43); Shaikh, Mohd. Siddique(12CE57); Siddiqui, Mohd. Iqbal(12CE59); Singh, Nitesh Kumar(12CE61)Pervious concrete is a relatively new concept. This concrete can be used for the rural road pavement, with relatively less traffic. As the concrete allows the water to pass through it, this would greatly help in recharging the ground water level. This has multifaceted benefits, including that for agriculture. Pervious concrete can be introduced in rural areas as a road pavement material. Pervious concrete as a paving material has seen renewed interest due to its ability to allow water to flow through itself to recharge groundwater level and minimize storm water runoff. In rural areas, cost consideration is the primary factor which must be kept in mind. In rural areas, storm water management practice is costly. Pervious concrete pavement is unique and effective means to meet growing environmental demands. In cities also, the pervious concrete pavements can be used for parking areas, garden, etc. It can be advantageously used as a replacement for the paver blocks. By capturing rainwater and allowing it to seep into the ground, this pavement technology creates more efficient land use by eliminating the need for retention ponds, well and other costly storm water management devices. However, the need for pervious concrete is of low grade, as there will not be heavy loads in parking area, garden, etc. In this project work, an attempt has been made to develop a low grade pervious concrete in the laboratory. The conventional concrete making materials are used for the same. However, the fine aggregates (sand) are not used. Only 10 mm coarse aggregates & 20 mm coarse aggregates are used. The proportion of concrete is 1 cement: 4 aggregates. Due to absence of fine aggregates, the concrete becomes porous in nature. This, in turn, allows the water to pass through it. The strength tests, workability tests & permeability tests are done on concrete to assess its properties & its suitability for the intended purpose.Item Experimental study of soil stabilization by using cement, lime and Potassium hydroxide(AIKTC, 2018-05) Patil, Dada S.; KHAN, ZISHAN MAHTAB ALAM (14CES24); JAMADAR, TALHA ZAHID (15DCES67); KAZI, MOHD ISMAIL ZAKI (15DCES69); MULLA, ABDULLATIF JABBAR (15DCES78)The use of soil stabilization is ever increasing due to technical, economic and environmental benefits. Soil stabilization methods are commonly used in highway projects where high strength of sub-soil is required. In physical and chemical stabilization, an optimum amount of cement, lime or any chemical is mixed with the soil to improve its quality. A practical and generally accepted approach is used to determine the optimum amount of additive to be added to the soil to get the maximum efficiency. In this work, an attempt has been made to carry out an experimental work, based on various results with different amount of additives ranging from 4%, 8% and 12%. The additives used are cement, lime and Potassium Hydroxide (KOH). Different properties of soil are determined for the campus soil. The important soil parameters are determined by incorporating different percentages of cement, (cement + lime) and (cement + lime +KOH). The results obtained can be utilized as a guide, as to what percentage and combination of additives is to be added in the soil when a particular soil property needs to be enhanced.Item Investigation on the characteristic properties of high performance SCC with mineral admixtures(Indian Concrete Journal, 2009-09) Patil, Dada S.In this experimental work, a mix design for self-compacting concrete has been carried out using Nan-Su method. Flow properties such as passing ability, filling ability, and segregation resistance were evaluated by varing the dosage of super plasticier (HRWRA) and viscoity modifing admixture.Item Light weight translucent concrete(AIKTC, 2020-05) Patil, Dada S.; Khan, Mohd. Aftab (13CE26); Khan, Atahar (14CE22); Malik, Fahad (14CE38); Ansari, Azra Banu (16CE01)Light Weight Translucent concrete is an upcoming innovation in construction engineering. Translucent concrete allows light to pass through it, with the presence of optical fibers embedded in the concrete. The principal objective of this project is to design the light weight translucent concrete blocks with the use of plastic optical fibers, fly ash powder and waste polystyrene (thermocol) to generate form of cement mortar. Compressive strength test and light transmitting test were conducted on concrete block to ascertain the practical utility of using translucent concrete. The project provides a new alternative to entrench the concept of sustainability and translucent concrete can be regarded as a green energy saving construction material. High emphasis is given to find out best ultimate possible solution of casting cubes with varying percentage of EPS as well as by the percentage of fly ash used in each trial. The output of project helps us in giving satisfying results so that use of these light weight translucent concrete can be bought into actual practice. Keywords: Translucent concrete, lightweight, polystyrene and fly-ash.Item Pile soil interaction by finite elements method in Abaqus(AIKTC, 2017-04) Patil, Dada S.; Ansari, Azhar (13CES07); Ansari, Junaid (13CES08); Barudgar, Mohd. Atique (13CES11); Khan, Abid (13CES20)Soil is a complex, heterogeneous material, having a strongly nonlinear response under action of external load. Due to this the constitutive laws associated to various soil types (cohesive, non-cohesive, saturated or unsaturated etc.) are continuously developed and improved. Analysis of soil had been and still a very challenging task for geotechnical engineers throughout the world. This is due to the non-linear behavior of soil and inability of constitutive relations in predicting exact behavior of soil. To overcome these difficulties in analysis, there is various material models has been developed with more complex constitutive relationship. Material models such as Mohr-Coulomb model uses very complex constitutive relationship. Solution of this complex partial differential equation is tedious and time consuming process, hence Finite Element Method is used to solve these equations. Present study focuses on the settlement analysis of pile foundation in a cohesive soil by using Mohr- Coulomb model. In addition to settlement analysis, this study also incorporates soil-structure interaction between pile and soil. The results obtain after the analysis shall be compared with analysis without soil-structure interaction and conclude the suitability of using Soil-Structure interaction in pile settlement analysis.Item Production and mechanical properties of high performance concrete(AIKTC, 2016-05) Patil, Dada S.; Arai, Affan (13CE67); Kamble, Dinesh (12CE24); Jain, Babul (12CE96; Lambate, Salman (12CE40)Increasing demands of the new millennium for sustainable and durable structures, and the limited available resources, have awakened the need for newer construction technologies and the efficient use of structural materials. Strengths of concrete such as tensile, flexural, shearing and bond strength are all related to the compressive strength. For this reason, it means that concrete with high compressive strength will also enhance other properties. Mechanical properties of hardened concrete are the most important property which civil engineers or everyone who work with concretes should pay attention. These properties are compressive strength, modulus of elasticity, tensile strength, creep and shrinkage. In this research, the first three properties of HPC were investigated. This Experimental investigation presents a study of properties of High performance concrete and comparing the properties with different codes and literature. The study focuses mainly on the properties like compressive strength, spilt tensile strength, modulus of rupture and modulus of elasticity of a high performance GGBS concrete by 0%, 5% and 10% of GGBS replacement with OPC to achieve strength of M60 and M80. For M60 and M80 grade concrete maximum strength achieved by replacing 5% GGBS with OPC and decreased for 10% replacement. In this study statistical equation has been proposed which is the relation between spilt tensile strength and cube compressive strength, and, modulus of rupture and spilt tensile strength. The equations proposed are in good agreement with ACI and other literature. The equations proposed by other literature are too conservative and need to modify for High performance concrete.Item Soil analysis and stuctural design of pile(AIKTC, 2017-05) Patil, Dada S.; Sayed, Abid (14DCE75); Shaikh, Jameel (14DCE78); Shaikh, Tausif (14DCE80); Ansari, Hammad (14DCE67)Pile foundations are often used in the soft soils to support heavy structures such as offshore towers, nuclear power plants, tall buildings, dams and bridges, There are many situations where these structure may go under dynamic loading, for example: earthquake forces, wave forces, wind forces, blasting and unbalanced machine etc. There has been a remarkable increase in the study of pile foundations in the latest twenty years although piles have been used for hundreds of years The purpose of this report is to analyse the soil and design the foundation by using static formulae. From the soil analysis and subsurface exploration, the foundation is recommended for the soil strata. Pile foundation consists of piles that are dug into soil till a layer of stable soil is reached. Pile foundations transfer building load to the bearing ground with the greater bearing capacity. Pile foundations are useful in regions with unstable upper soil that may erode or for large structures, pile foundations are often required to resist lateral loading. Lateral loads come from variety of sources including wind, earthquakes waves and ship impacts. The lateral capacity of pile is usually much smaller than the axial capacity and as a result, group of piles are often installed to increase lateral capacity of the entire foundation system. When vertical or plumb pile groups do not provide sufficient lateral resistance, the pies can be battered in order to mobilise some of the higher axial capacity to resist the lateral load.Item Structural auditing of RCC buildings(AIKTC, 2017-04) Patil, Dada S.; Momin, Mohd. Numan (13CES33); Khan, Mohd. Kalim (13CES53); Bhati, Mohd. Shahid (13CES12); Petkar, Nazim (13CES37)Structural Auditing is overall health and performance check up of the building like a doctor examines a patient. This process to create awareness amongst the residents and owners of building towards the health examination of existing concrete buildings called as Structural Audit. The need of structural audit is for maintenance and repairs of existing structures whose life has exceeded the age of 30 years to avoid any mishaps and save valuable human life. The concrete is widely used as construction material being inexpensive, easy for construction, applications and because of it high strength-cost ratio. More than ever, the construction industry is concerned with improving the social, economic and environmental parameters of sustainability. In India, from 1980 onwards the infrastructure industry witnessed stepping up of public investment and growth in infrastructure industry which resulted in construction of new multi-storey concrete apartments which are now in the age of thirty plus years. There are many buildings during this period and earlier that have reduced in strength in due course of time because of structural deficiency, material deterioration, unexpected over loadings or physical damage. lf further use of such deteriorated structure is continued it may endanger the lives of occupants and surrounding habitation. There is demand of appropriate actions and measures for all such building structures to improve its performance and restore the desired functions of structures which may leads to increase its functional life. The periodical structural auditing and diagnosis for health of existing buildings i s thus utmost important for finding the present serviceability and structural viability of structures. The structural audit must be carried out following auditing norms, methods of non-destructive testing and code provisions. The structural auditing will help to implement maintenance and repair work timely which leads to prolonged life of the building and safety of the occupants.Item Sustainable development through use of self-curing concrete(NBM Media Group Publication, 2022-09) Patil, Dada S.; Anadinni, S. B.; Shivapur, A. V.Concrete requires suffucient curing to attain the desired strengh as well as durability properties. If the concrete is not cured adequately, cement will not undergo full hyderation.Item Use of Rice Husk Ash in Concrete(International Journal of Scientific and Engineering Research, 2015-12) Syed, Mehdi Abbas (14CEM16); Patil, Dada S.This paper summarizes the research work on the properties of Rice Husk Ash (RHA) when used as partial replacement for Ordinary Portland Cement (OPC) in concrete. OPC was replaced with RHA by weight at 5%, 10% and 15%. 0% replacement served as the control. Compressive Strength test was carried out on hardened 150mm concrete cubes after at1, 3, 7, 28, 45 & 56 days curing in water. The results revealed that the Compacting factor decreased as the percentage replacement of OPC with RHA increased. The compressive strength of the hardened concrete also decreased with increasing OPC replacement with RHA. It is recommended that further studies be carried out to gather more facts about the suitability of partial replacement of OPC with RHA in concrete.
