Studies on Compressive Strength of Cement Concrete by Use of Rice Husk Ash with Sugar Molasses Waste

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 focuses on the effect of Rice husk ash and sugar molasses on compressive strength of concrete. The experiment has been carried out for evaluating the compressive strength of concrete by using of Rice husk ash as a replacement of Ordinary Portland cement and Sugar molasses as an admixture in the concrete composition. Five different percentages of sugar molasses viz. 0, 0.4%, 0.8%, 1.2%, 1.6% and 2% by weight of cement is chosen to demonstrate the experiment and at the same time OPC is replaced by Rice husk ash with 10% by weight of cement. Finally it is concluded that compressive strength of concrete is enhanced when admixtures like Sugar molasses added into the concrete composition.
