Physicochemical Structure And Properties Of Cement Stones With A Complex Chemical Additive KDj-3CHMB
Abstract
The technological properties of cement stone modified with a plasticizing complex chemical additive KDj-3CHMB have been studied. The influence of the additive on the basic properties of the cement stone has been investigated. The results of the research are given, indicating the active participation of improving the performance of concrete, as well as the possibility of reducing the amount of cement to 10-15%. The content of the additive KDj-3CHMB in the composition of the cement stone leads to an increase in its density by 7-10% and prismatic strength by 40% in comparison with the control samples. At the same time, the complex chemical additive KDj-3CHMB increases the indicators of mobility and frost resistance of cement stone
