Heavy density silica fume for gymnasiums cement

heavy density silica fume for gymnasiums cement:This type of Microsilica is usually added to cement used in the construction of stadiums to increase the strength and other properties of the cement.

Silica Fume will prolong the initial and final setting time of cement mortar after it is added into cement, so it is not suitable to be used in the season with low temperature;
Due to the strong water retention and segregation effect of the silica fume mixed into cement, the construction ease of cement will become worse with the increase of the dosage;
Through experiments and actual production shows that the silica fume as a mixed material of cement, the matter of mixing should be 3%, which can reduce the water demand, improve the early and late strength;
Silica fume has fine particles and small weight capacity, so storage, material stability and measurement should be considered when using silica fume.
