Anti-cracking, corrosion, waterproof additives
RA-HEA
Performance and use:
RA-HEA anti-crack corrosion waterproof agent is a rigid anti-crack waterproof material prepared by a variety of organic and non-unit. The product contains high-efficiency anti-crack components -- low-alkali high-efficiency expansion agent, plastic expansion component, anti-seepage shrinkage component. It successfully combines plastic expansion and hardened expansion with shrinkage organically to achieve the dual purpose of waterproof and anti-crack. The product meets the requirements of concrete waterproofing agent in JC474-2008 "Mortar, Concrete Waterproofing agent" industry standard. It has the properties of micro-expansion, compensation for the shrinkage of cement mortar and concrete, avoiding or reducing the cracking of mortar and concrete, early strength, water reduction, high workability, high permeability, reducing the heat of hydration and chemical erosion resistance.
