LITTLE KNOWN FACTS ABOUT SUPERPLASTICIZER.

Anionic surfactant has more robust adsorption on area of cement than that on surface of montmorillonite, granite and limestone. But cationic and nonionic surfactants have Considerably stronger adsorption on floor of montmorillonite and granite than that on floor of cement. When montmorillonite, granite and limestone are extra into cement mortar, th
