A Study on Use of Fly Ash Based Aggregate in Lightweight and Sustainable Construction

Abstract

For many decades steps and evolution has been made to invent a new process for strengthening the concrete. Countries like India use fly ash and bottom ash to reinforce construction work and several other types of ingredients in Reinforced Cement Concrete. Many civil engineers and industrials turn towards Fly Ash (F.A.)usage for building construction in recent times. These are the recent replacement that has been taken place in the construction sectors. The Expanded FlyAsh Clay Aggregate (EFCA) is used in addition to the F.A. and Botton Ash. In this paper, an investigation was carried out using the M20 concrete mix. This is done with Cement and F.A., Bottom Ash, EFCA, fine aggregate, and coarse aggregate at the rates of 6%, 12%, 13%, 22%, and 25%, respectively. The slip T.S. (Tensile Strength), compressive strength of the used mixture for concrete us also discussed. Their performance evaluation was considered on the basis of 7 days, 28 days, and 56 days. The F.S. (Flexural Strength) was evaluated on the basis of 7 days, 28 days, and 56 days. All these are done on the basis of optimum dosage of the replacement in the split (T.S.) and Compressive strength of the concrete mixture for the construction.
