Drizoro - Biseal Fume Silica Dust Supplement

A powder additive based on compacted silica dust, providing greater cohesiveness to freshly mixed concrete and mortar mixtures, reduces their run-off after application. After drying, it significantly improves their mechanical strength.

Features

• increases bending and compressive strength
• reduces the heterogeneity of fresh concrete
• increases chemical resistance to the influence of aggressive agents
• reduces material chipping when working with shotcrete
• improves the workability of fresh concrete

Application

• obtaining concrete and mortars of very good quality
• excellent strength of concrete and mortars at the initial and final stages
• significant improvement of the chemical resistance of concrete and mortars combined with their long-term durability
• obtaining shotcrete (shotcrete) intended for the wet and dry application method
