Annotation: The article presents the results of research work on the development of properties of binders with complex-mineral and at the same time chemical additives and the optimal compositions are determined. The use of local industrial waste as a secondary raw material in the production of new and modern types of building materials, namely fine mineral additives, ensuring the formation of a dense and durable structure of the concrete mixture, which achieves properties such as strength, frost resistance, without adversely affecting the cement hydration process, on the properties of a binder is one of the most important and relevant research areas at present [1–12]. Today, along with water, filler and binder, additives have become an indispensable component of the concrete mix. Among the many types of chemical additives, plasticizers occupy a separate place, especially the most effective of them – super plasticizers [1–12]. With regard to local construction practice, it should be noted that the use of super plasticizer in monolithic building technology is very low in the country. This can be explained by the fact that, firstly, in Uzbekistan, few chemical additives are produced for target concrete, including super plasticizers, and secondly, it is also a very urgent issue to conduct comparative studies of commercially available super plasticizers and develop recommendations for their practical use.
