SHRINKAGE AND CRACK RESISTANCE OF ROAD CEMENT CONCRETES WITH A COMPLEX ORGANOMINERAL MODIFIER
In this work, the study of the effect of a complex organomineral modifier on the properties of road cement concrete is considered. It has been found out that as the content of the additive reduces the shrinkage of concrete SRA, the moisture and shrinkage shrinkage of concrete decreases by 23...37 and 6...40 %, respectively, as well as evaporation rates and mass losses due to evaporation of moisture from the surface of concrete by 26...48 % . Taking into account the plasticizing effect of the SRA additive, it is possible to reduce the watercement ratio without degrading the technological properties of the mixtures, which will ensure the elimination of the negative influence of the additive on the strength of the concrete.
