摘要
对水泥混凝土道面在施工中产生早期裂缝、温度裂缝的原因进行了分析,并提出从合理选用混凝土配合比、重视温度控制、采用杜强纳米高强改性聚酯纤维和采用节水保湿养护膜养生可以防治温度裂缝和干缩裂缝。
Analysis is made of the reasons for the early cracks and temperature cracks in the cement concrete runway during construction, with proposals of selection of rational mix ratio of concrete, enhanced temperature control, using Duqiang nanometer high strength modified polyester fiber and the curing membrane to keep wet and stop cracks from temperature and shrinkage.
