Air Entraining and Water Reducer
MNC-AJ
Description
MNC-AJ contains no chloride and scanty alkali. Concrete applied with it features low slump loss and improved workability. It reduces water bleeding and segregation, improves impermeability, freeze/frost resistance and durability. It generates evenly, stable and durable bubbles, which meets the technical requirement of seaport, wharf, hydraulic project, road etc. It conforms to the Japanese concrete standard It meets the requirements of ASTM C 260, AASHTO M 154, and CRD-C 13.
Application
It’s used to produce fluidity concrete, ready-mix concrete, common grade concrete (C30-C50), hydraulic concrete and others which have special requirement on freeze/frost resistance and durability.
