Building materials from granulated blast furnace slag-Some newprospects S K Malhotra* & S P Tehri ... Clay brick is one of the basic building materials used in-construction activities. With the increasing demand of the bricks, the reserves ofgood quality soils are depleting steadily: In .
In 1880, mass slag concrete is reported to have been used in Pennsylvania; and in 1897 reinforced slag concrete was used in the construction of the Harrison Estate Building, Philadelphia, Pa. The earliest recorded application of slag as aggregate for reinforced bridge construction of considerable magnitude was its use in building the
Slag: From By-product to Valuable Construction Material ... But slag itself has value, and technologies have emerged to recycle and reuse reprocessed, granulated slag in different building materials, such as cement, brick, concrete aggregates, wall materials, and glass-ceramic tiles.
The slag obtained from different sources can be utilized as supplementary raw materials in different construction applications such as concrete aggregate, hot-mix asphalt and granular materials as investigated by various researchers [3-6]. The industrial application of granulated blast furnace slag is due to their enormous power of activation.
Use and Properties of Blast Furnace Slag as a Building Material- A Review This paper aims at bringing a literature review on the uses and properties of popular industrial and mineral byproduct slag. At the present, most industrial slags are being used without taking full advantage of their properties or disposed rather than used.
This specification covers three grades of finely ground granulated blast-furnace slag for use as a cementitious material in concrete and mortar. The material described in this specification can be used 1) for blending with portland cement to produce a cement meeting the requirements of Specification C 595 or 2) as a separate ingredient in ...
Samitinjay S. Bansode, in Characteristics and Uses of Steel Slag in Building Construction, 2016 4.1 Slag application in the cement industry As described in Chapter 2, granulated blast furnace slag consists of the same major oxides as does Portland cement, which explains why its first application was in the cement industry.
The solidified expanded slag is crushed and screened for use as a lightweight aggregate. EXPANDED SLAG USES - Lightweight masonry units, lightweight concrete, fire resistant construction, floor fill, concrete masonry core fill insulation, lightweight base or fill and cement manufacture. GRANULATED - Molten slag is chilled quickly to form a glassy,
Copper slag is used as a building material, formed into blocks. Such use was common in areas where smelting was done, including St Helens and Cornwall in England. In Sweden (Skellefteå region) fumed and settled granulated copper slag from the Boliden copper smelter is used as road-construction .
Apr 19, 2018· Copper slag can be used in concrete production as a partial replacement for sand. Copper slag is used as a building material, formed into blocks. Copper slag also has a high strength-to-weight ratio, making it an effective option in concrete, or a...
May 09, 2018· Chemical Composition of Ground Granulated Blast Furnace Slag. The composition of slag essentially depends on the raw materials used in the iron production process. Typical chemical composition contains calcium oxide 40%, silica 35%, alumina 13% and magnesia 8%.
of slag used in construction, i.e. slag aggregates, ground granulated blast furnace slag (GGBFS) and slag mixed with clinker in cement production. Many different properties were examined during the literature review, all segregated into separate categories based on the type of usage, particle size and chemical composition. The base samples ranged
Ground Granulated Blast Furnace Slag Blast Furnace Slag is a by product obtained in the manufacturing of Pig iron in the Blast furnace and is formed by the combination of earthy constituents of iron ore with lime stone flux. Quenching process of molten slag by water is converting it into a fine, granulated slag of whitish color.
While substitution of ground granulated blast-furnace slag for up to 70% of the portland cement in a mix has been used, there appears to be an optimum substitution percentage that produces the greatest 28-day strength. This is typically 50% of the total cementitious material but depends on the grade of ground granulated blast-furnace slag used.
Use and Properties of Blast Furnace Slag as a Building Material- A Review. ... The literary investigation was carried out on different forms of slag used in construction, i.e. slag aggregates, ground granulated blast furnace slag (GGBFS) and slag mixed with clinker in cement production. Many different properties were examined during the ...
The use of steel slag as an aggregate is considered a standard practice in many jurisdictions, with applications that include its use in granular base, embankments, engineered fill, highway shoulders, and hot mix asphalt pavement. Blast furnace slag products have been used successfully in virtually all phases of bridge construction.
durability enhancing characteristics when used in concrete. Ground granulated blast furnace slag also has a lower heat of hydration and, hence, generates less heat during concrete production and curing. As a result, GGBFS is a desirable material to utilize in mass concrete placements where control of temperature is an issue.
Samitinjay S. Bansode, in Characteristics and Uses of Steel Slag in Building Construction, 2016. 5.2 Slag utilization as an aggregate in concrete. EAF slag contains a small proportion of amorphous silicon and a high proportion of iron oxide. Get price
Ground granulated blast furnace slag (GGBS) is a by-product from the blast-furnaces used to make iron. Blast-furnaces are fed with controlled mixture of iron-ore, coke and limestone, and operated at a temperature of about 1,500°C. When iron-ore, coke and limestone melt in the blast furnace, two products are produced—molten iron, and molten slag.
Use of steel slag in construction of flexible pavement - IJEIT. as air-cooled slag or granulated slag. Steel making slag consists of converter slag (Basic oxygen furnace slag) that is generated by converter and electric arc furnace slag that is generated during the electric arc furnace steel making process that uses steel-scrap as the raw material.
