Experimental study on usage of industrial waste in road construction

Abstract

The Industrial Waste (phosphogypsum) is a waste product which was produced from the chemical industries. This waste material is used in concrete. It is ancient technique of converting the waste materials into value added products. When the industrial waste is utilized in construction industry, it may increase the availability of materials used for construction purpose and also reduces the expenditure made for disposal. It also reduces the pollution to the environment. The substitute material for changing materials used for laying pavement is got from industrial waste with agriculture based industrial waste. The main aim of this study deals with experimental investigation of test on concrete such as on compressive strength, flexural test, split tensile test, Characteristics of partial replacement of cement with 10%, 20%, 30% of Industrial Waste(phosphogysum). From this it was seen that when there is 20% replacement of cement with industrial waste, it gives a good test result then the other mix percentage. This type of concrete with industrial waste is very suitable for laying rigid pavement.
