膨胀剂的膨胀效能受到诸多因素的影响,比如环境温度、湿度、混凝土胶凝材料构成及混凝土强度发展速率等,膨胀剂在使用过程中有其最佳应用条件。本文着重探究养护温度对膨胀剂在混凝土限制膨胀率的影响规律。研究结果表明:养护温度越高,膨胀剂的膨胀效能发挥越早,但过高的早期强度会抑制膨胀的发展,过大的早期膨胀会影响强度后续的增长,只有强度和膨胀相互协调发展时,膨胀剂才能发挥出应有的补偿收缩作用。 Expansion agent expansion efficiency is affected by many factors, such as the ambient temperature and humidity, concrete cementitious materials and concrete strength of the development rate, expansion agent in the use of its best application conditions. This article focuses on the influence of curing temperature on the expansion rate of expansive agent in concrete. The results show that the higher the curing temperature is, the earlier the expansive expansive effect will be exerted, but the too high early strength will inhibit the development of expansion. Excessive early expansion will affect the subsequent growth of strength, and only when the strength and expansion develop in coordination , Expansion agent to play its due compensatory contraction effect.
