Influence of the particle size distribution of cements with different mineral additions on its physical properties

الملخص EN

This paper presents the results of an investigation into the influence of particle size distribution (P.S.D) after different times of grinding of two types of cements with various mineral additions (slag and tuff) on its physical properties.

This study analyzes the influence of particle size distribution (mean particle diameter "D50") on the consistency and setting time of cement paste.

The experimental work shows that cements with different mineral admixtures strongly activated have a faster process of hydration and shorter setting times.

The chemical composition and particle size distribution are the process factors affecting the hydraulic reactivity of the cement.
