Cement, Sand, coconut shell, coconut shell ash, recycle aggregate, coarse aggregateAbstract
Concrete is the main building material. The main ingredients of concrete are cement, fine aggregate and coarse
aggregate. There are lots of studies carried out to use waste material partially as ingredient. This project involve the
comparative study on concrete by partially replacing the combination of waste material like rise husk ash, recycle
aggregate, coconut shell ,coconut shell ash in concrete. The study will check the different parameter with different
replacement, such as economy, effect on compressive strength, workability of concrete, environmental effect. The
following combinations are proposed for the study for some particular grade of cement.
NORMAL CONCRETE
COCONUT SHELL ASH[5%] + RECYCLE AGGREGATE[10%]
COCONUT SHELL ASH[10%] + RECYCLE AGGREGATE[20%]
COCONUT SHELL ASH[5%] + COCONUT SHELL[5%]
COCONUT SHELL ASH[10%] + COCONUT SHEL[10%]
COCONUT SHELL[10%] +RECYCLE AGGREGATE[10%]
COCONUT SHELL[20%] + RECYCLE AGGREGATE[20%]
