Abstract

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.

At present, research aimed at using local waste management in the form of fine mineral additives, similar in material composition to the products of cement hydration, allowing directionally regulate the properties of the binder, achieve increased properties (strength, frost resistance), to form a dense structure of a mortar mixture. Reducing the consumption of the binder in mortar and concrete mixtures due to the introduction of modifying additives is also an urgent area of research. The paper presents the results related to obtaining a complex modifying additives consisting of waste of copper-smelting production and fly ash, studied its effect on the properties of cement systems. {1}

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} 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.
