Sulphate attack on cemented-bentonite-coconut coir

This study investigates effect of coconut coir (CC) on Portland cement (PC) blended with bentonite against magnesium sulphate (MgSO4). The mixtures were bentonite clay and 3, 5 and 7% PC and 2, 4 and 6% CC when cured for 7, 14 and 28 days. A total number of 78 UCS tests were conducted on both benchm...

description This study investigates effect of coconut coir (CC) on Portland cement (PC) blended with bentonite against magnesium sulphate (MgSO4). The mixtures were bentonite clay and 3, 5 and 7% PC and 2, 4 and 6% CC when cured for 7, 14 and 28 days. A total number of 78 UCS tests were conducted on both benchmark and MgSO4 exposed samples. PC treated samples indicated an enhancement in UCS beneath all circumstances. It was also noted that the addition of 2% CC was the most effective in this research. Also, the results showed that 4 and 6% coconut coir increment to be over-reinforcement and appears create a poor bonding forces and therefore lower resistance recorded.
