Can we use coconut shell as a coarse aggregate in concrete ...
Jul 23, 2017· Stronger the coarse aggregate greater will be the crushing strength of concrete. Generally used coarse aggregate in making concrete is "Crushed Stone". Crushing Strength: If you compare coconut shell with Crushed Stone Aggregate, the former is very weak in crushing and hence not desirable.
Recycled Aggregates
It is generally accepted that when natural sand is used, up to 30 percent of natural crushed coarse aggregate can be replaced with coarse recycled aggregate without significantly affecting any of the mechanical properties of the concrete.
