Abstract
Natural fibres are those fibre which are pollution free, environment friendly and does not have
any bad effect on climate. Every year there is ample amount of wastages of natural fibre .If these
natural fibres used as a construction material it could save the bio-reserves. They acts as green
construction material. Amongst all natural fibres, CF is the fibre which has the better physical
and chemical property also it is renewable, cheap, resistant to thermal conductivity, more
durable, highest toughness, most ductile then the other natural fibre, it is capable of taking strain
four time more than other fibres. Hence, CF is a best material to be used in construction.
The objective of this investigation is to enhance the strength properties of concrete using coconut
fibre. Addition of CF resulted into cohesive mix. To overcome this drawback the suitable dosage
of admixture was incorporated without effecting it strength properties.
In the present study the behavior of specimen with respect to compressive strength and the
cracking behavior of concrete and CFRC has been investigated. According to I.S. specification
different test is conducted to enhance the workability and strength properties by addition of CF.
different test such as slump test and flow table test on fresh concrete is carried out and
compressive strength and split tensile strength is carried out on hard concrete.
The present study involves the use of super plasticizer, master glenium 8654 (0.4% by mass cone
test) in M30 grade of concrete (grade ratio =1:1.918:2.898) which helps in enhancing the
workability without affecting the strength with CF (2%,3.5%,5%) and is compared with the
conventional concrete of same grade.
