The different test carried out on the steel slag aggregate such as the sieve analysis ,impact value test, crushing value test, water absorption test, specific gravity
We have tested the input properties of natural aggregates and steel slag for the powder density, absorption capacity, resistance to crushing, shape index).
In addition to this research several tests were also included such as compressive strength, split tensile strength and the flexural strength of concrete with steel slag
The steel slag is crushed to size and is normally produced through a range of sizes up to about 75mm. Both BOS and EAF steel slag have similar physical and.
Recycling and utilizing slag instead of treating it as waste enable cutting costs and Efficiency of material utilization is vital in any industry – steel mills and Recycled and processed slag can be sold and used for example as aggregates.
To compare the cost analysis using green concrete and the effect of partial replacement of aggregates by steel slag on the compressive strength of concrete. 4.

The study concluded that compressive strength of concrete improved by 4 to7 % at all the % replacements of normal crushed coarse aggregate with crystallized
Slag aggregates are obtained by crushing of smelter slag or by special treatment Utilization of steel slag as aggregate for stone mastic asphalt (SMA) mixtures.
The term 'aggregate' encompasses materials such as sand, gravel and crushed stone, which includes fine and coarse materials. Natural aggregates are mined
Iron and steel slag used in road construction is manufactured by crushing and in a mixture, and steelmaking slag is used as an aggregate for asphalt mixtures.
In addition, concrete containing steel slag aggregate displays satisfactory compressive strengths and flexural strengths [28–30]. Ultra-high performance concrete (
Production of sand and gravel, which until 1974 exceeded that of crushed stone, has increased at an annual rate of <1%. On the basis of these numbers, by 2020
Aggregate is the main component of Portland cement concrete. The coarse aggregates (with particle size more than 4.75 mm) that are obtained either from natural
Concrete made with heavyweight slag aggregate gives more compressive strength than other aggregates. Relationships between compressive strength and
