Concrete is one of the most widely used materials in the world. High-level and high-quality modern buildings put forward higher requirements for concrete economic indicators and quality performance. Slag powder is a kind of high-quality concrete admixture, which can replace part of cement in equal amount and obtain good economic benefits. What is the role of using slag powder processed by slag grinding mill as concrete admixture?

If you want to know the role of slag powder as concrete admixture, you should first understand what slag powder is. Slag powder is the abbreviation of granulated blast furnace slag powder. It is a powder made of granulated blast furnace slag conforming to GB/T203 standard, which has been dried and milled to reach a certain fineness and meet a certain activity index. The use of slag powder processed by slag grinding mill as concrete admixture can significantly improve and improve the overall performance of concrete. Slag powder can not only be used as a component material of concrete to prepare high-strength and high-performance concrete, but also be used to produce mass concrete and concrete with durability requirements under harsh environment.

The role of slag powder as concrete admixture is mainly to improve the bleeding and plasticity of concrete, accelerate the rate of hydration and heat evolution, help prevent cracks caused by the internal temperature rise of concrete, and can produce more ettringite microcrystals, thus compensating for the shrinkage of concrete caused by too much fine powder.

HCMilling(Guilin Hongcheng)’s HLM slag vertical roller mill is recommended for grinding slag. To produce high-quality slag powder efficiently and give full play to the role of slag powder as concrete admixture. It has the advantages of large output, high efficiency, small floor area and long service life.
