Abstract
The results of comparative studies of the influence of mineral additives on the rheological properties of cement compositions are presented. The proposed method for estimation of water requirement of mineral cement composition allows to use a small amount of material. It was established that the water requirement of granite and dolomite crushed powder as well as crushed recycled concrete depends on their density.
Keywords: mineral additive, spreadability, superplasticizer, thin filler, water requirement
