Abstract

Chemical prestressing was developed during the 1960s; however, and due to technical difficulties at that time, the technology was not considered as an alternative to conventional prestressing; instead, it was only used as a shrinkage compensating method. Still, recent development in concrete technology encouraged several researchers to revisit this technology, where significant achievements were made. This paper aims to present a state-of-the-art review about the recent development in the chemical prestressing technology. This includes reviewing existing field applications, existing types of expansive additives, influence of different expansive additives, influence of curing methods, mix proportioning, mechanical properties, and structural behavior. Furthermore, a thorough discussion was performed and suggestions were made for future researchers to help further contribute to the development of this prestressing technology. It was concluded that although the chemical prestressing technology seems very promising, more research is required before using it in practical applications.
