replacement of coarse aggregate, fine aggregate and cement. Its performance as a coarse aggregate replacement has been found to be non-satisfactory because of strength regression and expansion due to alkali-silica reaction. The research shows that there is strength loss due to fine aggregate substitution also. Efforts have been made in

Portland cement, as fine and coarse aggregates, to name a few. But steel slag has a negative impact on the environment when disposed. In that case wide variety of use of steel slag becomes relevant. Along with the diversified uses, steel slag efficiently replaces natural aggregates both coarse and fine…
crystallized & granular aggregates. The coarse aggregate were partially replaced by steel slag of about 10% and 20%. The fine aggregate were partially replaced by steel millscale of about 40%and 50%. This partial replacement of coarse and fine aggregates with steel slag and steel millscale will increases the strength of about 30% to 50%.
For alleviating negative impacts, more and more experiments have been carried out to explore the application possibility of steel slag. The purpose of this study is to explore the feasibility of steel slag being applied in induction healing asphalt concretes to replace coarse and fine aggregate.

has generated substantial solid waste. Steel slag is a residue obtained in steel making operation. This paper deals with the implementation of Steel slag as an effective replacement for sand. Steel slag, which is considered as the solid waste pollutant, can be used for road construction, clinker raw materials, filling materials, etc.
Aug 29, 2020· To solve the problem in effective manner steel slag and walnut shell is used in concrete by replacing natural aggregates. In this study, the replacement was done with fine aggregate by steel slag for different proportions of 0%, 10%, 20%, 30%, 40%&50% and coarse aggregate by walnut shell at constant proportion of 20%.
However, the optimum replacement of coarse aggregate with steel slag that gives better mechanical properties (compressive strength, tensile strength and flexural strength) than conventional
Jan 30, 2018· The diameters of coarse quartz sand, medium quartz sand, and fine quartz sand ranged from 0.63 to 1.25 mm, 0.315 to 0.63 mm, and 0.16 to 0.315 mm, respectively. The steel slag aggregate diameter range was the same as that of coarse quartz sand. Figure 3 shows the photo of the steel slag aggregate and coarse quartz sand.
Steel slag aggregates can be used as replacement for coarse and fine aggregates to specific percentages to get desirable results. Silica Fume Silica fume, also known as micro-silica, is a (non-crystalline) polymorph of silicon dioxide. It is an
It is advisable to not replace gravels with other consituents as possible as you can. Ofcourse coarse aggregates can be replaced with broken concrete debris however we are compromising the quality of resultant concrete upto some level that doesnt
