Influence of the pozzolanic reactivity of the Blast Furnace Slag (BFS) and metakaolin on mortars

The objectives of this study is to evaluate the pozzolanic reactivity of mortars with two mineral admixtures (Metakaolin and BFS) in substitution of cement. The rate of substitution is fixed after optimization of the mechanical results. Metakaolin and the BFS from blast furnaces have been used with 10% and 40% respectively to the replacement of the cement. At long time, the use of two admixtures provides better results to those of the mortar of...
