COMPARISON OF PROPERTIES OF STEEL SLAG AND CRUSHED LIMESTONE AGGREGATE CONCRETES Steel slag is produced as a by-product during the oxidation of steel pellets in an electric arc furnace. This by-product that mainly consists of calcium carbonate is broken down to smaller sizes to be used as aggregates in asphalt and concrete.

strength of Blast Furnace Slag aggregate concrete is found to be higher than that of conventional concrete at the age of 90 days. It has also reduced water absorption and porosity beyond 28 days in comparison to that of conventional concrete with stone chips used as coarse aggregate.

Indian Journal of Engineering & Materials Sciences Vol. 22, June 2015, pp. 339-344 Usage of steel slag in concrete as fine and/or coarse aggregate Gözde İnan Sezer* & Mert Gülderen Department of Civil Engineering, Ege University, İzmir, Turkey Received 27

Slag aggregates are obtained by crushing of smelter slag or by special treatment of fire-liquid slag melt (molten slag aggregates). Currently there are many types of concrete that are developed and used in construction that include metallurgical slags both as a binding component and as fillers.

 · When the steel slag and crushed concrete were soaked for 36 and 48 hours, it underscored the fact that AASHTO T 85 underestimates the absorption capacity of special porous coarse aggregates. A new proposed vacuum saturation approach is thus utilized to suck the trapped air within the effective pores while replacing it with water.

Key points. • ''Aggregate'' is a term for any particulate material. It includes gravel, crushed stone, sand, slag, recycled concrete and geosynthetic aggregates. Aggregate may be natural, manufactured or recycled. • Aggregates make up some 60 -80% of the concrete mix. They provide compressive strength and bulk to concrete.

 · Abstract. The applications of steel slag powder and steel slag aggregate in ultra-high performance concrete (UHPC) were investigated by determining the fluidity, nonevaporable water content, and pore structure of paste and the compressive strength of concrete and by observing the morphologies of hardened paste and the concrete fracture surface.

Slag Crusher Plant offered is used for crushing slag that is produced during smelting process through different processed applied in production. Slag in metals is present as form of undesired impurities at time of smelting which float to top in form of protective crust of oxides on top of metal being smelted, thus protecting liquid metal under it.

In concrete, processed steel and blast furnace slag provide a sustainable alternative to primary aggregates in the production of lightweight or dense ready-mixed concrete.
