The fly ash was a class F fly ash and was obtained from Jimah Power Plant, Tanjong Sepat, and Selangor, Malaysia. Quarry dust was obtained from Negeri Roadstone, Nilai, Negeri Sembilan, Malaysia.Fly Ash in Concrete Advantages & Disadvantages of Fly ,2 Fly Ash contains very small particles that make the concrete very thick and decreases the permeability of concrete. It could bring more power to the house. The concrete mixture produces a very low hydration heat, which avoids thermal cracking. Fly Ash concrete is immune to acid and sulfate attacks. The shrinkage of fly ash concrete is even smaller.use of fly ash and quarry dust in concrete,replacement of quarry dust is done Fly ash aggregates with fly ashcement proportions of 90 10, 85 15 and 80 20 was,The tensile strength of concrete with quarry dust and 25,30,35,40,45 and 50 flyash aggregate were tested is shown in the below graph.
