Abstract

Abstract: In India, construction industry plays a major role in building up nation's economy. For all the construction projects, approximately 60%–70% of cost has been spent on concrete. The annual consumption of concrete is about ten million tones. At the same time, abundant of fly ash has been thrown out as wastage. Fly ash, a by-product from the power plants, is effectively being used in the construction industry as an eco-friendly product. Concrete grade considered for this experimental study is M30 with 53 grade of Ordinary Portland Cement. About 50% and 75% cement was replaced by fly ash. Sand is replaced by the 5% of coir pith and 25%, 50% and 75% of quarry dust. IS method of mix design was adopted for obtaining required strength of concrete. Cubes (90), cylinders (90) and prism (60) were cast and cured. The cubes were tested for compressive strength on 7, 28 and 56 days. The cylinders were tested for split tensile strength on 7, 28 and 56 days. The prisms were tested for flexural strength on 28 and 56 days. The maximum strength is achieved in 5% coir pith and 75% quarry dust as replaced by the sand.
