Effects on Flexural Strength of Concrete by using Rice Husk Ash as Partial Replacement of Cement with Addition of Sugar Molasses

With the increasing demand of cement due to rapidly increasing construction works, research and development works has been going on to obtain the supplementary cementing material which can raise the strength and provide high performance to overcome this challenging demand. These supplements can be any of these viz. natural materials or by-products of manufacturing industries or industrial wastes or such materials whose manufacturing requires less time and energy. This paper emphasizes the effect of Rice husk ash and sugar molasses on strength properties of concrete. The experimentation has been carried out for evaluating the strength properties of concrete by using Rice husk ash as a replacement of Ordinary Portland Cement and Sugar molasses as admixtures into the concrete composition. Five different percentages of sugar molasses are chosen in the experimentation as 0, 0.4%, 0.8%, 1.2% & 1.6%, 2% by weight of cement and OPC is replaced by Rice husk ash with 10% by weight of cement. Finally it is concluded that flexural strength of concrete enhanced when admixtures like Sugar molasses added into the concrete composition.
