The properties improvement of UHPC incorporation cellulose fiber and the autogenous shrinkage reduction mechanism with internal curing effect

Journal of Materials Research and Technology
Internal curing has been proven to be an efficient way to inhibit shrinkage of ultra-high performance concrete (UHPC). Cellulose fiber (CF), which has a hydrophilic surface and lumen structure, is a suitable internal curing agent without self-volume ...
