抄録
An experimental investigation was conducted to study the effects of a temperature history on the strength development and autogenous shrinkage of concrete containing supplementary cementitious materials (SCMs). The experimental results demonstrated that the physical properties of concrete containing SCMs were affected by the temperature history. Although the strength development at early ages was accurately estimated using the maturity method, a reduction in the long-term compressive strength was found in concrete specimens that were cured at high temperatures. Additionally, a substantial increase in the autogenous shrinkage was observed in concrete specimens that were fabricated with ground granulated blast-furnace slag and cured in semi-adiabatic formworks.
