EXPERIMENTAL INVESTIGATION ON VITRIFIED POLISH WASTE AND RICE HUSK ASH AS PARTIAL REPLACEMENT OF CEMENT

Rigid pavements are considered superior to other types of pavements due to their ability to with stand traffic loads, thermal stresses acting on the pavement, high flexural strength, durability, and low maintenance cost when compared to flexible pavements. However, Rigid pavements are not a major component of India’s transportation system of rules because their construction costs are very high and cement is the primary ingredient. In this study to analyze the optimum replacement of cement with industrially produced materials such as vitrified polish waste (VPW), Rice husk ash (RHA). Mix design is done for varying proportions of Rice husk ash (RHA) and Vitrified polish waste (VPW) as replacement of cement in 0%, 5%,10% 15%, 20% by weight of cement. Specimens were casted, tested and compared in terms of compressive strength and flexural strength to the conventional concrete. These tests were carried out to find out the mechanical properties of concrete such as workability, compressive strength and flexural strength after a curing period of 7days and 28days. Results were obtained at 10 % replacement of cement by Vitrified Polish Waste and Rice husk ash to attained optimum strength of concrete.
