STUDY ON EFFECTS OF PARTIALLY REPLACING CEMENT AND SAND WITH RHA, AND GLASS POWDER WASTE

Abstract

This research work was experimentally carried out to investigate the effects of partially replacing Pozzolonic Portland cement (PPC) with our local biomaterial additive {Rice Husk Ash (RHA)} and sand with glass powder waste which is known to be super pozzolanic in concrete at optimum replacement percentage. With this research work, the problem of waste management of this agro - waste will be solved. The compressive strength value at 7,14,21 and 28 days was found to be 20.27, 28.34 ,33.67,37.60N/mm2 at the replacement percentage of 20 % in earlier researches. Glass waste is one of the major problem now days, as its production is in high rate and the decompose properties are very low. The main motive of this experiment is to decrease the usage of cement as due to the wide rate of construction the exploitation of raw material is increasing and cement production also releases harmful gases(SO2,NOX).
