Use of Blast Furnace Slag Aggregate in Concrete

The use of blast furnace slag aggregates in concrete by replacing natural aggregates is a most promising concept because its impact strength is more than the natural aggregate. Steel slag aggregates are already being used as aggregates in asphalt paving road mixes due to their mechanical strength, stiffness, porosity, wear resistance and water

Properties of Hardened Concrete with Blast Furnace Slag

Jan 16, 2017 At 7 days and beyond, the flexural strength of slag concrete is equal or exceeds controlled concrete flexural strength. The larger flexural strength of blast furnace slag concrete is the result of the stronger bond which is achieved in cement-slag-aggregate system due to slag particle shape and surface texture. Figure-4 shows slag particles.

What is GGBS? Its Advantages and Disadvantages

Oct 02, 2020 What is Ground Granulated Blast Furnace Slag (GGBS)? The ground granulated blast furnace slag (GGBS) is a by-product of iron manufacturing which when added to concrete improves its properties such as workability, strength, and durability.. This material is obtained by the heating of the iron ore, limestone, and coke at a temperature of about 1500 o C. The process is carried out in a blast furnace.

Concrete aggregate : Iron and steel slag products : NIPPON

JIS standards were formulated for blast furnace slag course aggregates in 1977, and for fine aggregates in 1981. These standards have been incorporated into recommendations for a variety of practices by the Architectural Institute of Japan and the Japan Society of Civil Engineers, and these aggregates have earned a place as an important construction material.

Use of Blast Furnace Slag Aggregate in Concrete K.G. Hiraskar and Chetan Patil Abstract-The Iron industries produce a huge quantity of blast furnace slag as by–product, which is a non–biodegradable waste material from that only a small percentage of it is used by cement industries to manufacture cement.

Fly Ash, Slag, Silica Fume, and Natural Pozzolans, Chapter 3

SLAG Ground granulated blast-furnace slag (Fig. 3-5), also called slag cement, is made from iron blast-furnace slag; it is a nonmetallic hydraulic cement consisting essentially of sili-cates and aluminosilicates of calcium developed in a molten condition simultaneously with iron in a blast furnace. The molten slag at a temperature of about 1500°C

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;

Slag Cement Questions

Blast furnace slag aggregate comes in two forms: Air cooled blast furnace slag, results when molten slag from a blast furnace slag cools slowly by ambient air (as opposed to rapid quenching), and is processed through a screening and crushing plant for use principally as a construction aggregate. Air cooled slag is not cementitious.
