Abstract
eco-efficient cementitious composites are widely used in buildings and structures which are usually exposed to high temperatures and high pressure because of their high temperature resistance abilities. In order to figure out the effects and mechanisms of supplementary cementitious materials (SCMs) on improving high temperature resistance of eco-efficient cementitious composites, the effects of fly ash (FA), silica fume (SF) and granulated blast furnace slag (GBFS) on residual mechanical properties of thermally damaged cementitious composites were systematically reviewed based on some relevant literatures. Also, self-healing properties of thermally damaged eco-efficient cementitious composites induced by post-fire-curing were summarized to better understand the comparative roles of SCMs. The results showed that FA and GBFS were favorable to improve the residual properties, but SF was less effective than FA and GBFS. Extensive cracking and spalling were more frequently performed on heated cementitious composites containing SF. However, all these SCMs were effective to improve the self-healing properties of thermally damaged cementitious composites. This review mainly focuses on developing functionalized cementitious composites with both high temperature resistance and self-healing. Furthermore, to promote high volume utilization of SCMs in developing eco-efficient cementitious composites is another purpose of this review.
