Application of slag powder and ultrafine powder in cement and concrete

Slag powder is a type of fine powder formed by grinding slag, with a particle diameter generally less than 15 microns and good activity. It can be used to replace some clinker or limestone in cement, and is used in cement manufacturing; It can also be used as a concrete admixture to improve the strength and durability of concrete.

Ultrafine mineral powder is a mineral powder with a particle size distribution between 5-20 microns after processing through grinding, grading, and modification. It is mainly used for the preparation and reinforcement of concrete, improving its performance and service life.

In cement manufacturing and concrete production, there are the following differences:

1. Cement manufacturing: Both slag powder and ultrafine powder can replace some of the clinker or limestone in cement, reducing production costs; Slag powder can also improve the durability, early strength, and hardening time of cement, while ultrafine slag powder can improve the compressive strength of cement.

2. Concrete production: Both slag micro powder and ultrafine slag powder can be used as concrete admixtures, which can improve the strength and durability of concrete. Especially, slag micro powder can also improve the fluidity of concrete, reduce the temperature rise rate of concrete, and improve the early strength and ductility of concrete.

In summary, there are differences between slag micropowder and ultrafine slag powder in terms of particle size, usage, and composition, but both play important roles in cement manufacturing and concrete production.
