90% Densified Silica Fume Announcements

In the application of high-strength, high abrasion resistance, underwater casting of anti-scattering concrete, etc., the amount of silica fume admixture should not be too low usually accounting for 5%-10% of the cementitious material.

Use Ewende Silica Fume Powder preparation of high-strength, early-strength concrete should be used with high-efficiency water reducing agent, with high-strength concrete should be selected with low air-entraining high-efficiency water reducing agent, depending on the situation can add defoamer.

In ordinary strength, impermeable, highly durable or self-compacting concrete applications, it is appropriate to use a multi-component cementitious material with low silica fume admixture, usually accounting for 2%-5% of the cementitious material.

The addition of silica fume powder needs to extend the mixing time, can not be mixed in wet concrete after mixing, it is recommended to extend the mixing time of 30 seconds than ordinary concrete to ensure uniform mixing.

Plastic shrinkage crack sensitive, better maintenance method is: spray concrete has not yet set, spraying curing agent maintenance; concrete hardening, the use of maintenance film, covered with wet sacks or plastic film.
