Experimental Study on Flyash and Lime With Gypsum in Concrete

ABSTRACT Conventional concrete is responsible for amount of carbon-dioxide emission to some Extent. So to reduce the emission, various types of concrete are developed using waste products from industries and agricultural use like blast furnace slag, silica fume, fly ash which requires low Amount of energy and also cause least harm to the environment. Falg concrete is a new technology developed now days to reduce the effect on environment by production of cement. Cement contains high amount of carbon-dioxide which harms the environment drastically, so by replacing the cement by various materials which causes harm to the environment we not only reduce the problem of disposal of these materials but we reduce the emission of carbon-di-oxide from cement. This study concerns with the use of fly ash and lime to improve the strength of concrete. An experimental investigation has been carried out by replacing the cement with falg by 0%. 10% and 20% for M30 grade of concrete. The main aim of this project is to investigate the compressive strength, split tensile strength and water absorption of M30 grade of concrete. Keywords: Concrete, Falg, M30 grade and Split tensile strength.
