A multicomponent additive comprises microsilica which has been stabilized by means of one or more water reducing agents alone or in combination. This mixture is especially of advantage as additive to cement and mortar and results in an improvement of plasticity, workability and strength as compared to usual cements and mortars. The additive can be mixed with water whereupon more microsilica is added for formation of a slurry. |
