In this study, steel slag was used to replace sand as an aggregate in concrete. The compressive strength and break load were the same for both materials but the steel slag concrete broke into much smaller pieces. The leaching from the steel slag concrete and from regular concrete are similar for all metals except chromium.

Jul 03, 2015· Blast furnace slag is a byproduct from blast furnaces which is used to produce iron. Blast furnace slag has been used extensively as a successful replacement material for Portland cement in concrete materials to improve durability, produce high strength and high performance concrete, and brings environmental and economic benefits together, such as resource conservation and energy .
The lead containing components are processed in blast furnaces for hard lead or rotary reverberatory furnaces for fine particles. The blast furnace is similar in structure to a cupola furnace used in iron foundries. The furnace is charged with slag, scrap iron, limestone, coke, oxides, dross, and reverberatory slag. The coke is used to melt and ...
Blast Furnace Slag has been used in Canada as a road and plant base material since the early 1900''s. Steel Slag was originally used in the 1970''s and and consisted of premium surface course HMA. There was extensive use in 1980''s and by the 1990''s there was in excess of 488,000 tonnes consumed in a variety of applications.
On its own, ground granulated blast furnace slag (GGBS) hardens very slowly and, for use in concrete, it needs to be activated by combining it with Portland cement. A typical combination is 50% GGBS with 50% Portland cement, [4]but percentages of GGBS anywhere between 20 and 80 % are commonly used.
Oct 01, 2019· Slag is a byproduct of metal smelting, and hundreds of tons of it are produced every year all over the world in the process of refining metals and making other industrial byproducts, slag actually has many uses, and rarely goes to waste.

A 30m stretch of road is being trialled with 15m of traditional concrete and 15m of a geopolymer concrete. Nine sensors have been positioned under the concrete to monitor and compare how the geopolymer concrete performs. The results from the trial will be used to create the first set of industry guidelines for geopolymer concrete.
