THE INFLUENCE OF MATERIALS OF CHEMICAL ADDITIVES ON THE PROPERTIES OF BINDERS
Keywords:
Chemical additives, mixture composition, compressive strength, durability, water-cement ratio, stratification.Abstract
The article presents the results of research work on the development of properties of binders with chemical additives and the optimal compositions are determined.
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.
