Study on Effect of Steel Dust on Strength Characteristics of Concrete

摘要

Conservation of natural resources and preservation of environment is the essence of any development. The problem arising from continuous technological and industrial development is the disposal of waste material. The utilization of waste material in concrete, not only can reduce the cost of construction, but also proves to be a safest method of its disposal. In this project a similar effort is taken to find the feasibility of such a waste material in concrete technology. This paper deals with the idea of finding suitable proportions of steel slag that could be related in attaining the target strength of concrete. Experiments were conducted to find the compressive strength and split tensile strength of concrete of M25 grade, with OPC 53 grade of cement and 60% 20mm and 40%12mm coarse aggregate. The fine aggregate was replaced by steel dust by 10%, 20%, 30%, 40% and 50% by weight of fine aggregate, were the optimum percentage was found out to be 30%. Fly ash of class F was used to replace cement by 30% by weight of cement and Ceraplast300 was used as superplasticizer to attain strength and workability.
