PHYSIO-CHEMICAL ASSESSMENT OF RICE HUSK ASH (RHA) BLENDED CALCIUM CHLORIDE (CaCl^sub 2^) AS SUPPLEMENTARY CEMENTING MATERIALS

This study examine the effect of rice husk ash (RHA) blended calcium chloride (CaCb) as supplementary cementing materials. The replacement levels of OPC with rice husk ash (RHA) were 0%, 5%, 10%, 15% and 20%. 1% of calcium chloride was blended with OPC/RHA in all experimental work. The following phy...

Description
Summary:This study examine the effect of rice husk ash (RHA) blended calcium chloride (CaCb) as supplementary cementing materials. The replacement levels of OPC with rice husk ash (RHA) were 0%, 5%, 10%, 15% and 20%. 1% of calcium chloride was blended with OPC/RHA in all experimental work. The following physical properties were determine on OPC and RHA; fineness test and specific gravity test while standard consistency and setting time test were conducted on OPC/RHA and OPC/RHA/CaCb. The chemical composition of OPC and RHA was also determined. The result of the standard consistency revealed that as the percentage replacement increases, the consistency also increases for both OPC/RHA and OPC/RHA/CaCb respectively. However, the initial and final setting time shows that OPC/RHA/CaCb set faster than OPC/RHA.
