slugAn Experimental Study on Partial Replacement of Natural Coarse Aggregate With Fly Ash Coarse Aggregate (FACA)
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2014, Vol 2, Issue 6
Abstract
A construction industry plays vital role in India which leads into the economic developments. The materials like a cement, fine aggregate & natural coarse aggregate which is used to prepare concrete where once easily available in our country, but now there is high demand in materials which has gone to a high scenario. In this project an experimental investigation is done on the partial replacement of coarse aggregate with fly ash aggregate. The quantity of fly ash produced from thermal power plants in India is approximately 80 million tons each year, and its percentage utilization is less than 10%. Majority of fly ash produced is of Class F type. During the last few years, some cement companies have started using fly ash in manufacturing cement, known as ‘pozzolana Portland cement, but the overall percentage utilization remains very low, and most of the fly ash is dumped at landfills. Many researchers have been carried out in the area of fly ash utilization in the past. It mainly concentrated on replacement of cement with fly ash but production of artificial aggregates with fly ash helps in utilizing large volume of ash in concrete. The world is much interested in this part recently due to this large scale utilization which also reduces environmental pollution and dwindling of natural resources. This paper mainly focuses on manufacturing process of light weight aggregates.The production of fly ash aggregate is produced in ratio of 10:90, 15:85 and 20:80.Based upon the above mix ratio, fly ash aggregates are produced and used for casting the concrete cubes and cylinder for comparing the strength with conventional aggregate concrete at 7 and 28 days curing period.
