Abstract
Temperature dependency of autogenous shrinkage of ultra high-strength concrete whose binder is premixed silica fume cement with W/B=0.15 is investigated. Experimental factors are temperature of fresh concrete and elevated temperature history that are emulating difference of temperature history due to placing season. As a result, the following conclusions are obtained 1) Autogenous shrinkage of ultra high-strength concrete has two stages from the point of view of a rate of shrinkage, i.e., earlier age (Stage1) and later age (Stage2), 2) Lower temperature of fresh state increases autogenous shrinkage at Stage1, 3) Higher temperature develops larger autogenous shrinkage, especially over 40°C at Stage2, 4) the reduction of autogenous shrinkage was observed in the case that the applied temperature dilation was given to the specimen before the age of starting development of autogenous shrinkage.
