Experimental investigation of rice husk ash brick using M-Sand and F2R cement with perma plast AC

Abstract

In this study of investigation of rice husk ash, it can be used in preparation of rice husk ash brick. Engineering properties like compressive strength ,water absorption ,size and shape have been studied. .F2R cement is special used for increasing the workability for M-sand. M-sand is used to satisfy the carsity of river sand. Since rice husk ash has more absorption of water, to minimize the water absorption Perma plaster AC is used .From the studies it is observed that optimum proportion for RHA + M-sand + F2R cement was observed as minimum 30% of RHA .when compared to all other possible proportions after 28 days curing period the rice hush ash brick achieve nominal strength compare to clay brick.
