Manufacturing Process

Copra Crushing/Oil Extraction Dried and Roasted Copra pieces are now fed into an expeller with screw press for mechanical crushing under high pressure. Oil squeezes out of copra during this process leaving the fibre out. Crushing is employed in 2 stages where 1st crushed copra is again crushed for the 2nd time to recover maximum oil.

Durability properties of treated coconut shell-used concrete …

The absorption capacity of coconut shell (CS) aggregates is 20–25% absorption due to their inherent porosity. Hence, if CS is treated, there are chances of reducing its porosity from 2.370 to 0.315% and, in turn, may enhance its durability performances when used in concrete production. Therefore, this study has investigated …
