aggregate in concrete and water cooled granulated slag is used as a partial substitution for sand in concrete. Reports show that air cooled ferrochrome slag has gained popularity as a coarse aggregate in concrete. But the use of water cooled rochrome slag is lagging behind. ( Dash, Patro, 2018).Details
Effects of aggregate properties on Concrete like Grading of aggregates depends on the proportions of coarse and fine aggregate. If grading of aggregate is varied, it also changes cement paste content (cost economy), workability of the mix, density and porosity. It is an important factor and has a maximum influence on workability.Details
