Effect of Steel Slag as Partial Replacement of Cement on Property of Concrete

A well maintained infrastructure is a fundamental necessity for a modern society that provides great value, but ensuring that it meets all the requirements is challenging. Concrete as a construction material is in use for several decades. Concrete can withstand the severest environments and engineers are constantly trying to improve its performance with the aid of modern admixtures and waste materials with or without cementious properties. The use of waste material in concrete helps to consume these waste materials and also improves the properties of concrete in fresh and hydrated states.Civil structures are designed considering the target compressive strength of the concrete. Although, few other parameters such as workability, water to cement ratio, setting time of cement and surface hardness influence the performance of concrete.In the present research a series of experiments had been performed to compare the use of Steel Slag as partial replacement of cement in different proportions. Concrete mixes are modified by 5 10 , 15 , 20 and 25 of Steel Slag as replacement of cement.The main conclusions drawn are inclusion of Steel Slag increases the compressive strength up to a certain proportion and then reduces the strength. Steel powder increases the strength but reduces the workability. Comparatively higher early strength gain 3 days, 14 days, 28 days is obtained with Steel Slag concrete.
