ContactAutogenous strain of cement pastes with superabsorbent polymers. Internal curing of high performance cementitious mixtures by superabsorbent polymers, SAP, reduces self-desiccation and self-desiccation shrinkage. Depending on the type and on the dosage of the SAP, shrinkage may be totally avoided and early-age expansion may be observed.

Contact2002年11月1日 This article provides an overview of the phenomenon of autogenous healing. Autogenous healing of concrete occurs when continuity between two sides of a crack is restored without a deliberate external intervention or repair. In most cases, the cracks are narrow and caused by shrinkage extensive enough to induce locally a strain larger than the tensile strain
Contact2005年1月1日 Autogenous healing of concrete was reportedly discovered as early as in 1836 by the French Academy of Science, and attributed to the transformation of calcium hydroxide (Ca (OH) 2 ) into calcium
Contact2019年9月9日 Concrete cracking induced by shrinkage has always been considered as a major concern of concrete durability and structural safety control. In recent years, high strength concrete has been widely used in practical engineering [].Prior studies have shown that autogenous shrinkage is the primary factor leading to the cracking of high strength concrete.
Contact2015年5月1日 The results of a laboratory investigation on the early autogenous shrinkage of high strength concrete, and the possibilities of its reduction, are presented. Such concrete demonstrates significant autogenous shrinkage, which should, however, be limited in the early stages of its development in order to prevent the occurrence of cracks and/or drop in the load
