中文摘要：
论述了在无掺合料高强超高强高性能混凝土的试验结果与分析的基础上，论述了有掺合料高强超高强高性能混凝土的试验结果与分析，得出了各掺合料的活性指数，引入水化活性因子和减水剂增量系数进行高强超高强高性能混凝土配合比的修正为超高强高性能混凝土配合比的设计提供了一种实用的方法。
英文摘要：
The deformations of cement pastes and mortars with or without UEA and light calined magnesia expansive agent were studied. Cement pastes and mortars were pre-cured for different time and then cured in two relative humidities.The influences of two kinds of expan- sive agents with replacement percentages of 0 and 6% on the drying shrinkage of cement pastes and mortars were compared and analyzed.The experimental results show that two kinds of expansive agents produced effective expansion in the dry air curing conditions, had an excellent ability to compensate for drying shrinkage of cement pastes and mortars.UEA hydrated faster and the expansion of it occurred before 14 d compared with light calined magnesia expansive agent.The time ofpre-curing in water had clear implication on UEA＇s expansion.
