EFFECT OF FLY ASH AND MARBLE POWDER ON STRENGTH OF PAVEMENT QUALITY CONCRETE

In this era with growing industries, Uncontrolled disposal of industrial waste can lead to environmental pollutions and irreparable damages. Managing industrial waste is one of the ways to protect our environment from harmful pollutants. As such, manufacturers and companies should be held responsible for the waste they generate., we need to think about our environment and to overcome this issue Concrete pavement construction is growing throughout the country due to its strength, durability, excellent performance, and overall long-term savings. There is a need to develop better road sections that can withstand heavy loads. This can be achieved using high compressive strength concrete made from OPC cement with fine to coarse aggregate. In the construction, we will use industrial waste to carry out the construction. Fly ash is a by-product of burning coal in a thermal power plant, and marble powder is a by-product of the Marble industry. Fly ash and marble powder are used as additional cementitious materials to improve the properties of cement concrete. This study aims to develop paving concrete by partially replacing the cement with fly ash and marble powder 10% and 20%. The purpose of the study is to compare the resistance properties of concrete pavements achieved by the concrete mix. Fly ash is a waste product that is produced due to the burning of coal in power generating plants. And concrete consists of cement, sand, fine, and coarse aggregate. With the rise in industrial pollution global warming has been increasing at a steady pace. Smoke and greenhouse gases are being released by industries into the air, which causes an increase in global warming to make eco-friendly concrete, cement can be interchangeable with a certain amount of fly ash and marble powder this can improve the strength of pavement concrete. The fly ash has taken in this research is from HEG Limited. Mandideep, Near Bhopal, and exist in of Class F category This experiment pertaining to the replacement of OPC (Ordinary Portland Cement, 43 grades, IS 8112)[1] along with fly ash and marble powder is done and to get the desired compressive and flexural strength. Of grades M30, M40 Polymer-based superplasticizer is used. The compressive and flexural strength of PQC (Pavement Quality Concrete) with different percentages of fly ash has and marble powder studied for 7 and 28 days It is observed that the mixes with fly ash replacement showed higher flexural strengths for all water to cement ratios.
