Abstract
Abstract: Construction industry consumes a huge volume of concrete every year and the demand for concrete as a construction material is on the increase. The main ingredient of concrete is cement and India is the second largest producer of cement in the world. The attention to environmental impacts of cement production has grown faster in recent decades. The cement industry is a significant greenhouse gases emitter mainly due to the calcinations of raw materials and the combustions of fuels. Portland cement production is increasing globally and contributes to greenhouse gas emissions. The current contribution of greenhouse gas emission from Portland cement production is about 1.5 billion tons annually or about 7% of the total greenhouse gas emissions[11].This leads to the utilization of wastes and industrial by-products in order to minimize the Portland cement consumption and also focuses on using eco-friendly concrete. In this experimental study There are 13 trials have been conducted on M40 Concrete in this study. out of 13trials , one trial is with control mix, 6 trials with Flyash at 60,70&75% of OPC replacement and the remaining 6 trials with GGBS at 60,70&75% OPC replacement. The investigations are being conducted for the fresh concrete properties like Workability of concrete, Temperature of concrete, Yield of concrete and Air percentage in concrete.
