Baking-free brick, a promising building material, was produced from manganese slag with the addition of quicklime and cement. The physical properties, chemical composition, and mechanical performances of the obtained samples were measured by several analyses and characterization methods.
fineness in a 'cement' mill – creating Ground Granulated Blast Furnace Slag (GGBFS). GGBFS has a long history of use as a cementitious material in a number of countries, but in Australia its use began in about 1966 as a cement replacement in concrete used in the expansion of the steel works at Port Kembla. This use continued over the next 20
It is of great importance to innocuity, minimization and reutilization of manganese slag generated in manganese product by electric furnace process. In the paper, ordinary Portland cement was replaced partly by manganese slag to then evaluate manganese slag' effect on mechanical performances of them. The experimental results obtained show that ordinary Portland cement added less than 30% by ...

Ground-granulated blast-furnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a by-product of iron and steel-making) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder.Ground-granulated blast furnace slag is highly cementitious and high in CSH (calcium silicate hydrates) which is a strength enhancing ...
A cement is a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel together.Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete.Concrete is the most widely used material in existence and is only behind water .
In order to inquiry the effect of manganese slag powder on the asphalt mixture pavement performance, With the asphalt mixture specimens produced by adding manganese slag powder of 1.5, 3.0, 4.5and 6.0 % into AC-16I asphalt mixture, the Marshall test, freeze thaw split test and rutting test were conducted. From the diagrams the corrosion resistance and high temperature stability performance and ...
