In the process of concrete mixing, introduce numbers of micro-bubbles with uniform distribution, which can significantly improve the frost resistance and durability of hardened concrete.
Air entrainment is an innovative chemical admixture with high performance.
When used in cement industry it can generate high stable micro foam throughout the concrete mixture. The performance can not be affected by water hardness.
It can reduce the bleeding rate, but not increase the viscosity.
SJZ-A1 basis on Rosin Resin, it is used together with SNF better
SJZ-A2 basis on Polyether Alkyl sulfonates, it could use together with SNF and PCE.
0.5‰ - 1‰
Please be noted the amount to be used will vary with local materials and intended concrete.
Store in a cool, dry place. Avoid moisture and heat.
