- Cementation of hazardous liquid waste is one of the methods to minimize its detrimental effect on the environmental quality and human health. This research purpose was to study the effect of temperature on the cement block reinforced by coconut (Cocos nucifera) fiber and bamboo (Bambusa vulgaris) fiber. This research was pursued by adsorbing stronsium waste and chrom using zeolite. 13% v/o of zeolite was mixed with 0,3 of water/cement ratio and 0,5% v/o of natural fiber. The cement blocks produced were heated at 27°C. 50°C, 100°C, 150°C, 200°C and 250°C for 10 minutes and then investigated their compressive strength and leaching rate. The hydration reaction completely works when cement block is heated until certain temperature that results in the increasing of its compressive strength. Over heated results in the decreasing of compressive strength due to the enlarging of pores between cement matrix and fiber. However, the compressive strength of cement block heated up to 250°C is still beyond the standard Based on its compressive strength, the bamboo (Bambusa vulgaris) fiber is more feasible than coconut (Cocos nucifera) fiber for reinforcing cement block Heating just influences on the physics properties of cement block But, the ability of block cement to immobilize a matter is affected by properties of matters.
