Quantitative Assessment of the Development of Stress in High-Performance Concrete in Restrained Conditions with an Internal Curing Agent
Abstract: A new test method for two rings, 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, is characterized for early behavior of concrete that expands and deforms. This study proposes a new methodology for assessing the potential for cracking, which has implications for mitigating (reducing, preventing) early cracking in concrete. Internal curing is a method in which an absorptive material is incorporated into a mixture that acts as an internal reservoir that can reduce or eliminate early-age autogenous and restrained shrinkage and also reduce the potential for early cracking due to plastic shrinkage or shrinkage during «self-desiccation».
Keywords: autogenous shrinkage, internal curing, lightweight aggregate, residual stress, ring test, high-performance concrete, restrained shrinkage.
