Drizoro - příměs do betonu a malt Biseal SRA

A liquid additive that, when mixed with water to prepare the material for application, reduces shrinkage of concrete and mortars during their plasticization and drying, reducing the risk of cracking during their maturation.

Features

• works in concrete and mortars by reducing the surface tension of water, thus minimizing the risk of cracking in them
• Reduces the risk of concrete and mortar shrinkage during plasticization and drying by up to 40%, depending on the composition of the mixture
• increases the durability of concrete structures and the resistance of reinforcing steel to corrosion, in cracks it reduces the penetration of water, salt and other aggressive chemical compounds
• the material is compatible with Biseal SCC, Biseal SPF and Biseal POL superplasticizers, Biseal Fume silicate powder additive and Biseal CEL air penetration additive
• does not contain chlorine or any other substances that may corrode reinforcing steel
• on fresh concrete it has a cohesive side effect, reducing material delamination
• reduces the cost of repairing cracks and creating a surface finish

Application

• suitable for system in industrial flooring
• suitable for concrete exposed to aggressive external conditions and constant contact with water in applications that require low permeability and a reduced risk of cracking
• suitable for concrete and mortars with a proportionately high water content
• Suitable for mortars intended for screed screeds, for plastering, for surface layers, etc.
• suitable for concrete poured over large surfaces and applied in unfavorable weather conditions: high temperatures, high winds, open sun, etc.

Technical data

• external appearance transparent liquid
• yellow color
• specific gravity 1.07 0.05 g / cm ³
• chloride content <0.05%
