养护剂对道路混凝土早期开裂的影响

Effect of curing agents on early cracking of road concrete

针对道路混凝土早期开裂现象,设计蒸发率、早期开裂试验对3种养生剂进行比较,研究养生剂对混凝土硬化阶段水分散失和早期裂缝形成的影响。研究表明:养生剂对混凝土不但起到了保湿作用,还缩短了其水分散失的时间进程,对混凝土裂缝的数量、长度和宽度均有明显的抑制作用。

For the phenomenon that road concrete early cracking,evaporation rate and early cracking testing was done to compare the different between three curing agents by the influence to water loss and crack formation.Studies have shown that:curing agent not only played a role that moisturizer,but also shortened the time of its water loss.Then,the quantity length and width of concrete cracks were significantly inhibited because of increasing the amount of curing agent.
