Effect of specific surface area of cements on the mechanical properties of mortar

Abstract EN

This work is a contribution to the improvement of the properties of the mortars by mechanical activation of two types of cements (C.

E.

M II) manufactured in various cement factories (cements with various mineral additions : slag and tuff).

The physical properties of cements (C.

E.

M II) activated mechanically at anhydrous state and the hydrated state (specific weight, consistency of the cement pastes and setting times), thus the characteristics of the mortars made at their bases, such as, the mechanical behavior (Flexural and compressive strengths for the mortar) were studied.

According to the experimental results obtained, it comes that the increase of the specific surface and the chemical composition of cements with the mineral additions are the principal responsible to the improvement of the latent reactivity of mineral additions and increase the mechanical strengths (flexural and compressive) of the mortars.
