Abstract Various shrinkage-reducing agents and expansive admixtures have been developed to decrease the drying shrinkage of concrete at construction sites. However, concrete with added shrinkage-reducing agents has been reported to exhibit low frost resistance and low compressive strength during the early curing stages. It is possible to use an expansive admixture such as the K-type additive, composed of calcium sulphoaluminate, which contains an alumina source such as bauxite. Here, we develop… Expand

Experimental Study on Freezing and Thawing Cycles of Shrinkage-Compensating Concrete with Double Expansive Agents
In this study, a shrinkage-compensating concrete based on a double expansive admixture was developed and its frost resistance was assessed through rapid freezing and thawing cycling, providing a basis for the study of frost resistance in large-scale hydraulic concrete structures. Expand


Combined effect of expansive and shrinkage reducing admixtures to obtain stable and durable mortars
Abstract In order to improve the dimensional stability of cement based mortars, the effects produced on cement hydration of a shrinkage reducer (propyleneglycol ether based—SRA) and an expansiveExpand
Effects of MgO-based expansive additive on compensating the shrinkage of cement paste under non-wet curing conditions
Abstract Expansive additives are widely used to compensate the drying shrinkage of cement-based materials to avoid cracking. However, the expansion of conventional ettringite-bearing expansiveExpand
Interactions between shrinkage reducing admixtures (SRA) and cement paste's pore solution
Abstract Shrinkage reducing admixtures (SRA) have been developed to combat shrinkage cracking in concrete elements. While SRA has been shown to have significant benefits in reducing the magnitude ofExpand
