Abstract
The development in the construction industry all over the world is progressing day by
day. High-tech and modernized designs are being built and old buildings are being
demolished or renovated. One of the things builders, developers and contractors must
consider during construction, renovation or demolition is where to put all the debris. When
structures made of concrete are to be demolished, concrete recycling is an increasingly
common method of disposing of the rubble. Concrete debris was once routinely shipped to
landfills for disposal, but recycling has a number of benefits that has made it more attractive
option in this age of greater environmental awareness, more environmental laws, and the
desire to keep construction costs down. In this study, we are aiming to design a concrete
debris mixture as mortar mix that will meet the IS requirements, in order to help contribute to
the industry in saving the environment, to encourage the government to find solutions
regarding the disposal to landfills of waste materials and save the environment, to provide
new knowledge to the contractors and developers on how to improve the construction
industry methods and services by using recycled concrete debris, and to sustain good product
performance and meet recycling goals. The objectives of this project are to prepare a mix
design of M20 grade concrete using concrete rubble from demolition site and admixture
(super-plasticizer), to prepare a mix design of M25 grade concrete using concrete rubble from
demolition site and admixture (super-plasticizer), to carry out Slump Cone Test on the above
mentioned concrete mixes, to carry out Compressive Strength Test on the above mentioned
concrete mixes, to carry out different tests on recycled aggregates & natural aggregates &
compare their results and to finally conclude the effectiveness of concrete recycling based on
the above test results
