Replacement of Coarse Aggregate by Using Naturally Available Materials

Abstract

The major part of construction industry is based on concrete. In concrete the vital and costly material after cement is aggregate. Hence it affects economy. Also coconut being widely produced in states of Maharashtra, Kerala, Karnataka and region nearby seashore. Coconut shells can be available in adequate quantity. According to study on coconut shell concrete it is found that the course aggregate in concrete can be replaced by coconut shell and it gives 65% strength that of conventional concrete. From references it reflects that there is study on partial replacement coarse aggregate by coconut shell is done. Also rubber latex is used for increasing strength of concrete. Coconut shell and rubber latex used as admixture in concrete gives different strength and results. If we combine coconut shell and rubber latex together the concrete of higher strength and economical as well as eco-friendly concrete can be obtained. In this project the aggregates will be replaced by coconut shell and rubber latex as admixture to change the properties of concrete as well as to achieve maximum strength than normal concrete. The tests conducted on fresh concrete are Slump cone, Compaction factor test and Vee-bee test. Also tests conducted on hard concrete are Compressive strength, Flexural strength and Split tensile test. The Coconut shell rubber latex concrete is very economical than conventional concrete and it is also eco-friendly and strength of both the concrete is approximately same.
