SHRINKAGE DEFORMATIONS OF MODIFIED CONCRETE. CAUSES AND REMEDIES
The reasons for the formation of various types of cracks in concrete structures, the influence of such deformations on their operational properties and durability are considered. The results of the analysis of the causes of the appearance of internal stresses, leading to crack formation in the elements taking into account all stages of its production, are presented. The data on the effect of SRA additive on the loss of moisture from a concrete mixture at the age of up to 20 hours are given as well as a comparison of the appearance of cracks in a concrete of a freshly molded sample in comparison with the no-additive composition of concrete.
