通过比尺试验来研究不同养生方式下新铺水泥混凝土试验板24 h内温度变化规律及不同温度场环境下混凝土试验板内应变变化规律,提出减小新铺水泥混凝土试验板温差的合理养生措施。试验结果表明,喷白色养生剂和铺草垫两种养生方式可以有效降低混凝土试验板的内外温差,对于防止混凝土试验板裂缝的产生具有重要的意义。
Through the scale test to study the law of temperature variation of the newly-laid cement concrete test plate under different health regimen in 24 h, and the variation of strain in the concrete test plate in different temperature field environment, the reasonable regimen to reduce the temperature difference of the cement concrete test plate . The results showed that spraying two kinds of health preservatives and laying mats two ways of health can effectively reduce the temperature difference between the inside and outside of the concrete test plate for the prevention of cracks in the concrete test plate is of great significance.
