摘要
研究了添加膨胀组分的复合矿物掺合料混凝土的短期抗冻性能。设计了20个配合比试验来评价混凝土的性能,研究发现,在掺合料取代率为40%时混凝土具有较高的短期抗冻性,对于矿粉-膨胀组分复合型掺合料,膨胀剂占掺合料比例从8%～12%变化时,混凝土短期抗冻性能随膨胀剂掺量的增加而增大。
In this experiment, the short-term frost resistance of concrete mixed with expansive compound mineral admixture is ed. Based on a contrastive concrete experiment of 20 mix proportions, it is concluded that the concrete mixed with 40% mineral admixture has the largest short-term frost resistance. In addition, if the expansive agent in compound admixture of ad slag and expansive component ranges from 8% to 12%, the short-term frost resistance increases.
