浅谈大体积混凝土温差裂缝产生及控制

Discussion on the production and controlling of the thermal-gradient-induced cracks in massive concrete

对大体积钢筋混凝土固化过程中,由于水泥水化热形成的温度场所造成的温差裂缝的产生和发展进行了分析。从减小温差裂缝影响的角度出发,提出了各种控制裂缝产生的措施。

In the present paper, the production and evolution of the thermal-gradient-induced cracks in massive concrete were discussed. In order to minimize the influence of these cracks on the concrete structure, some relevant methods for crack-controlling were presented.
