Properties of Fly Ash Aggregate a??An Alternative to Natural Aggregates- An Experimental Study

摘要

In this paper details of experimental studies carried out on fly ash aggregates as a replacement to stone aggregates has been presented, these aggregates are economical and environmental friendly. The artificial fly ash aggregates are manufactured by using ordinary mixer, in three different proportions of cement and fly ash, they are 12.5:87.5, 15:85, and 17.5:82.5 in the form of pellets. the experiments conducted are Grain size distribution, Specific gravity, absorption, impact value, crushing value, fineness modulus of three different proportions of fly ash aggregate as per the Indian standards and the results are comparing with natural aggregates. The 17.5:82.5 proportions aggregates give good strength properties, fly ash aggregates is a good alternative for civil engineering works.
