66.67% steel slag aggregates as a replacement of the coarse aggregate. Qurishee et al.(2016) in their experimental study on the use of slag as coarse aggregate and its effect on mechanical properties of concrete. It was reported that compressive strength of concrete made by replacing coarse aggregate with slag is higher than normal conventional

Utilization of Steel Slag in Concrete as Coarse Aggregate

study has been conducted to explore the possibility of utilization of steel slag in concrete as coarse aggregate. After collection of steel slag aggregate from a local steel manufacturing company, the steel slag aggregate was separated into lightweight (SL), heavyweight (SH), and mixed (SM) slag aggregates. The

Slag: The All-Purpose Aggregate | TMS International

Slag: The All-Purpose Aggregate. Slag is sometimes erroneously classified as industrial waste. In fact, this product can be recycled into valuable, versatile construction materials for green use. We utilize slag, a product of steelmaking, in versatile construction material for environmentally beneficial use.

Usage of steel slag in concrete as fine and/or coarse ...

In this study, the use of steel slag as fine and/or coarse aggregate in concrete is investigated. For this purpose, 12 different concrete mixtures with different water/cement ratios of 0.40, 0.55 and 0.70 which include steel slag aggregate as fine and/or coarse aggregate are prepared.

Concrete Materials - Mix Components - The Concrete Network

These materials include fly ash, slag cement (sometimes called ground granulated blast furnace slag—GGBFS or slag cement), silica fume, and metakaolin. SCMs are used as replacement for cement, and since they have a very small particle size, they reduce the permeability of concrete, which is good.

Use of Air-Cooled Blast Furnace Slag as Coarse Aggregate ...

coarse aggregate in concrete pavements. The report discusses ACBFS aggregate production and properties, and the properties of concrete produced with ACBFS coarse aggregate. Both the physical and chemical properties of ACBFS are presented, as are the properties of the concrete produced with ACBFS coarse aggregate.

Durability of concrete made with EAF slag as aggregate ...

Concrete made with EAF oxidizing slag as an aggregate shows good physical and mechanical properties and further study of its durability will ensure greater reliability in its usage. This paper details a systematic study of slag concrete behaviour under severe test conditions.

SLAG CONCRETE MASONRY - Phoenix Slag Services

Data from Table XI, "Slag Concrete Masonry Units," National Slag Association. Fire Resistance and Thermal Insulation: The concrete masonry units made with slag aggregates have low thermal conductivities. As a result, the slag units have better insulating properties and fire resistance for a given thickness of solid material in a wall than

Aggregates for Concrete - University of Memphis

blast-furnace slag is also used as fine or coarse aggregate. The aggregates are usually washed and graded at the pit or plant. Some variation in the type, quality, cleanli-ness, grading, moisture content, and other properties is expected. Close to half of the coarse aggregates used in portland cement concrete in North America are gravels;

Construction aggregate - Wikipedia

Construction aggregate, or simply "aggregate", is a broad category of coarse to medium grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates. Aggregates are the most mined materials in the world.

Ground granulated blast-furnace slag - Wikipedia

Two major uses of GGBS are in the production of quality-improved slag cement, namely Portland Blastfurnace cement (PBFC) and high-slag blast-furnace cement (HSBFC), with GGBS content ranging typically from 30 to 70%; and in the production of ready-mixed or site-batched durable concrete. Concrete made with GGBS cement sets more slowly than ...

Slag Cement Questions

Slag cement proportions of 40 to 50% normally optimize strength. Concretes made with slag cement will generally exhibit higher flexural strength for a given level of compressive strength. Modulus of elasticity follows the same relationship as OPC concrete, when based on compressive strength.

Use of Steel Slag Aggregate in Pavements Report - …

Steel slag aggregate (SSA) is a byproduct of the production of steel in an electric arc furnace. The high iron oxide content of the aggregate results in an aggregate that is very hard and very dense (SSA is 20-30% heavier than naturally occurring aggregates such as basalt and granite).

How to Expose the Aggregate - The Concrete Network

Abrasive blastingIt's also possible to expose the aggregate after the concrete has set and hardened by using abrasive blasting (either sandblasting or shotblasting). The disadvantage of abrasive blasting is that it can fracture the aggregate and dull its appearance.
