摘要:
运用电涡流方法测量混凝土早期收缩，研究了水胶比、引气剂和矿物掺合料等因素对混凝土早期收缩性能的影响．结果表明，水胶比为0.45的混凝土3 d收缩率可达到78×10-6，复掺硅灰矿渣和引气剂时，混凝土3 d收缩率达到113×10-6；随引气剂掺量增大，混凝土早期收缩增加，但在正常掺量范围内引气剂的影响较小；混凝土成型后400~1 500 min为水泥水化放热高峰，其早期收缩曲线出现膨胀或收缩减缓现象．
Abstract:
To understand early age shrinkage of concrete in order to get high performance concrete，an eddy current method was used to measure the early age shrinkage of concrete with different water-binder ratios and mineral admixtures such as fly ash，slag and silica fume and air-entraining admixture．The results show that the shrinkage of concrete with water-binder ratio of 0.45 reached 78×10-6 and that of concrete incorporating slag，silica fume and air-entraining admixture reached 113×10-6 in 3 days. Addition of air-entraining admixture increased slightly the shrinkage of concrete．The expansion segment between 400 min and 1500 min after casting in the shrinkage curve of concrete may result from a relatively large amount of hydration heat produced.
