coconut shell concrete

2017-6-1  Properties of coconut shell makes it suitable ingredient for concrete production and its use for concrete may help in its disposals problem. 2. Replacement of conventional aggregate by waste coconut shell (keeping quantity of other ingredients unchanged) results into decrease in compressive strength. 40% replacement resulted in about 22% reduction in the 28 days strength.
