Abstract EN
This paper investigated the influences of shrinkage reducing agent and expansive admixture on autogenous and drying shrinkage of ultrahigh performance concrete (UHPC) containing antifoaming admixture.
The shrinkage reducing agent was used at dosage of 0.5%, 1%, and 2% and the expansive admixture was used at dosage of 2% to 4% by mass of cementitious material.
The results show that the air content of UHPC increases with the higher addition of shrinkage reducing agent and expansive admixtures.
However, the fluidity, compressive strength, and shrinkage of UHPC exhibit a declining tendency.
The usage of expansive agent at dosage of 4% significantly reduces the shrinkage of UHPC.
The 7-day autogenous shrinkage was decreased by 16.0% and 28-day drying shrinkage was decreased by 29.5%, respectively.
Shrinkage reducing agent at dosage of 2% reduced the 7-day autogenous shrinkage by 44.3% and 28-day drying shrinkage by 50.2%.
Compared with expansive admixture, shrinkage reducing agent exhibits more efficient shrinkage reduction effect on UHPC.
