Uses of air-entraining water-reducing admixtures
The use range of air-entraining water-reducing admixtures is as wide as that of air-entraining agents. Basically, air-entraining water-reducing admixtures can be used instead of air-entraining agents …
Retarding water reducing agent and its properties and uses
The water reduction rate index of retarded water reducing agent is the same as that of ordinary water reducing agent. The air content of concrete can reach less than 5.5%, which is wider than other wa…
