　　The purpose of study the results of which are reported and discussed in this paper was to analyze state-of-the-art with regard to plasticizing alkaline cements and to develop solutions for the use of plasticized alkaline cements in contemporary concretes.A necessity to plasticize alkaline cements arises from structural instability of some chemical admixtures that are effective in case of OPC in highly alkaline environment (pH =13.0-13.6).The results of study showed that superplasticizers based on polyesters had lost their steric effect due to hydrolysis.
