理论和施工经验表明 ,新拌混凝土的温度对混凝土的工作性、强度、耐磨性及早期开裂等性能有着重要影响。作者在长益、益常和湘耒路的混凝土路面施工中 ,对该问题进行了较深入的研究 ,通过试验和施工得出了一些有意义的成果 Theoretical and construction experience shows that the temperature of fresh concrete has an important influence on the properties of concrete such as workability, strength, wear resistance and early cracking. In the construction of concrete pavement of Changyi, Yichang and Xianglv Road, the author carried out a more in-depth study of the problem and obtained some meaningful results through experiments and construction
