Abstract
In today’s scenario, we always think for the optimization in each field to get the maximum potential with lower cost. And so our engineering persists, we engineers got the respect. On the other hand, to save our environment is the prime concern, obviously, the concern of this research paper is. This research paper desires to obtain the optimized quantity of fly ash in concrete of grade M15, M20, M25,M30,M35,M40.Optimization of fly ash in concrete is varying the amount of fly ash as replacement of the cement which acts as a binder material. The replacement of larger proportions of cement by fly ash will reduce the cost of concrete, improves the intrinsic property like durability of the structure also the consumption of by product waste material fly ash from the coal based power plant as a resource material. Portland slag cement confirming IS: 455-1989 and high lime fly ash which is categorised as class C fly ash by ASTM, because of its high calcium content ,is used for the each trial mixes of concrete .High lime fly ash will act as binder material along with cement, also it’s pozzolanic nature improves the durability of the concrete The physical and chemical properties most importantly, its fineness and carbon content imparts vital role in water cement ratio and strength parameters in concrete. Several design mixes will be prepared, cured and tested for their compressive strength. Each compressive strength sample will be tested at 7and 28 days. The results will be analysed and compared with standard concrete and conclusions made on how best the fly ash can be utilized to give optimum results. Earlier attempts for optimizing the fly ash content in cement concrete is with the Ordinary Portland cement. It is exciting to optimize the fly ash content with the Portland Slag Cement, a huge cost relieves for concrete production.
