Superplasticizers high-range water reducers

Due to the rapid slump loss associated with first- and second-generation superplasticizers (high-range water-reducers), job site addition of such... [Pg.551]

Superplasticizers (high-range water reducers HRWR, ACI 212.4R-04) are used for similar purposes as plasticizers, but with increased effects, and water may be reduced by 15-30%. Such results cannot normally be obtained by increasing the amount of a plasticizer without a risk of large side effects considerable slow down of the rate of cement hydration or excessive porosity. [Pg.102]

A general update of references and developments in all chapters including a major new chapter on superplasticizers , or high-range water-reducing agents. [Pg.23]
