High-Performance Concrete with Restrained Shrinkage
Abstract: To prevent restrained shrinkage of high-performance concrete used complex modifiers are used such as: high water-reducing superplasticizer; an expanding component of calcium oxide; an expanding agent that reduces the surface tension of water. This complex increases the effectiveness of each product (the so-called synergistic effect), which partially or completely eliminates shrinkage. It reduces the risk of rapid moisture evaporation of due to climatic conditions hardening. To quantify restrained shrinkage technique «ring test» is used, according to ASTM C1581-04 Standard Test Method for Determining Age at Cracking and Induced Tensile Stress Characteristics of Mortar and Concrete under Restrained Shrinkage.
Keywords: high-performance concrete, restrained shrinkage, modifier, restrained admixtures.
