A Study on Mechanical Properties of Concrete Replacing Fine Aggregate with Steel Scrap

Now a day without concrete we can’t imagine the world so in such conditions as a civil engineer it is the ultimate job to get the maximum output at reasonable input without causing any effect to the nature nothing but environment. High density concrete was mainly used in the construction of nuclear power plants, rail sleepers, counter wait for lifting cranes and in many other structures also. The main aim of this paper deals with the high density concrete that means to get the maximum density by using the locally available material steel scrap (mild steel bars dross) as a replacement of fine aggregate in different proportions of 50% and 100% with the considerable water cement ratio. This may result the change in physical and chemical properties like density, compressive strength, tensile strength, freeze-thaw resistance and apart from all these the main foremost thing is it should resist the thermal property also. Here the fine aggregate replacement by steel dross is economical because this steel dross is locally available material we can get this from the metal cutting workshops that is maximum there is no use of this regarding any activity in any area. By doing the sieve analysis for the steel dross it came under zone II as here the replacement is of fine aggregate(FA) is also the same zone so it an advantage to obtain the optimum results.
