Superplasticizer are water reducing agents and when added to concrete mix, they improve the workability, cohesiveness, strenght and durability of the concrete. If you use admixtures in your construction works the difference is always clear. |

Microsilica is used in concrete. When it is used in concrete, it acts as a filler and as a cementitious material. The small microsilica particles fill spaces between cement particles and between the cement past matrix and aggregate particles. Microsilica also combines with calcium hydroxide to form additional calcium hydrate through the pozzolanic reaction. Both of these actions result in a denser, stronger and less permeable material. |
