Mechanical grinding of steel slag is investigated and characterized using X-ray diffraction and size analyzer. The results indicate that the obtained ultrafine powders contain active mineral phases suitable for ordinary Portland cement (OPC)-Ca(OH)2, 2CaO·SiO2, 2CaO·Fe2O3. We have proved and first pointed out that the steel slag induces phase transition during grinding process and the Blaine ...

Mar 01, 2019· The GGBS in this work was commercially available ultra-fine slag of two sizes (V1 and V2), Nitrogen BET Surface area of V2 (3955 m 2 kg −1) was found to be much higher than the V1 (2435 m 2 kg −1). The (CaO + MgO)/SiO 2 ratio by mass (M, coefficient of basicity) was a reliable indicator of reactivity, Calculated M = 1.55 of the UFS.
The application of ultrafine ground-granulated blast-furnace slag (GGBFS) in concrete becomes widely used for high performance and environmental sustainability. The form of ultrafine slag (UFS) used in concrete is powder for convenience of transport and store. Drying-grinding-drying processes are needed before the application for wet emission.

Use slag slag powder for construction. After using the grinding mill to grind the slag, it can be used as building materials for the production of cement and concrete. Because the slag has potential hydraulic gelling properties, it can be used as high quality under the action of .
Silica fume, also known as microsilica, (CAS number 69012-64-2, EINECS number 273-761-1) is an amorphous (non-crystalline) polymorph of silicon dioxide, silica.It is an ultrafine powder collected as a by-product of the silicon and ferrosilicon alloy production and consists of spherical particles with an average particle diameter of 150 nm.
Application of ultrafine fly ash grinded by low quality fly ash in commercial concrete was studied, and the studied content included fineness test, mortar strength, concrete strength, admixtures adaptability, impermeability and dry shrinkage. Results show that ultrafine fly ash grinded by low quality fly ash had a very good activity and admixtures adaptability, can greatly improve the strength ...
Ultrafine cements are particulate, cementitious grouting materials that were initially developed as a replacement for unacceptably toxic chemical grouts for Civil Engineering applications. Several basic types are available: ultrafine slag cement (Ml), ultrafine portland cement (M3) and ultrafine portland/slag (M5).
