ABSTRACT This study is based on the use of sawdust ash as a partial replacement material for cement in concrete for property modifications. In the concrete mixes, cement was replaced by sawdust ash at 5%, 10%, and 15% by weight, and the effects on replacement were observed. The use of sawdust ash allows the reuse of sawdust as a waste product in the construction process. Due to the lightweight of the sawdust ash in comparison to cement, the concrete ultimately becomes lighter in weight. The grade of concrete designed here was M25 and concrete cubes measuring 150mm×150mm×150mm, beams of sizes 100mm×100mm×500mm and cylinder 150 mm in diameter and 300 mm in height were cast and their compressive, flexural strength, and split tensile strength are evaluated respectively after 7 and 28 days. INTRODUCTION The construction industry is in constant demand due to the ever-growing population and its infrastructural demand. Adequate and affordable building materials are in need for the construction of infrastructure to meet both domestic and commercial demands. The conventional building materials have been increasing exponentially over time and in turn making the construction projects unbearably expensive, at the same time the majority of the world’s population continues to subside below the poverty line. Due to this, there has been a search demand for alternate building materials for the construction purposes of infrastructure in both urban and rural areas without a compromise to their normal functions. In the construction world, one material is dominantly used above all others, and that is concrete. Concrete according to Neville (1983) is a composite material that consists of a binding medium within which are embedded particles or fragments of aggregate. According to an article by Jonathan Watts et al (2015); concrete is the most widely used substance on the planet, after water. Its worldwide production and use exceed that of steel by the tenth factor in tons and by YMER || ISSN : 0044-0477 VOLUME 21 : ISSUE 8 (Aug) - 2022 http://ymerdigital.com Page No: 699
