Concrete with Manufactured Sand and the Effects on the Property of Durability

Abstract

The concrete is the material generally used in the construction industry. The natural aggregates are the essential materials used in the concrete, but it is observed that there is a shortage of these materials. Therefore, the cost of the material and eventually the construction cost go on increasing across the globe. The manufactured sand i.e. m-sand is a material which can replace the natural fine aggregates if used in proper proportion. Also, the m-sand can be produced in a good amount so that the construction cost is also not affected. In the present work, manufactured sand concrete is studied for the durability properties. Other materials like zinc oxide are also used in the concrete by weight of the cement. The partial replacement of river sand by m-sand is carried out in the percentage varying from 25% to 100%. The tests for the durability which involve water permeability test, acid attack test, sea water test and sulphate attack test have been carried out for the concrete. When the river sand is replaced by m-sand with 50% then the results for the durability obtained hold good results.
