expansive oil well cement with high strength low filtration anti pollution

Chemical Admixtures - Portland Cement Association

Consequently, concrete containing a water-reducing admixture needs less water to reach a required slump than untreated concrete. The treated concrete can have a lower water-cement ratio. This usually indicates that a higher strength concrete can be produced without increasing the amount of cement.
