Investigation on Various Properties of Cement & Concrete with MSWI-Ash and M-Sand as Partial Replacement

Cement is the most widely used construction material because of its mould ability into any structural form and shape due to its fluid behaviour at early stages. In the combustion process of municipal solid waste (MSW), bottom ash (BA) represents the major portion of the solid residue. Since BA is composed of oxides, especially SiO2 and CaO, the feasibility of its application in concrete as a substitute for cement was tested. This paper reports a study on the use of municipal solid waste incineration ash as a replacement to the cement to calculate the properties of the design mix composition. Four design mix compositions comprising 10%, 20%, 30% and 40% replacement of MSWI ASH with cement were formulated and the tests like initial setting time, final setting time, consistency, sound ness, specific gravity, and strength of cement were carried out for those proportions It is found that at the age of 28 days the strength of samples are satisfactory and are as per the standards of Indian codes.
