随着工业化进程的发展及混凝土使用的逐渐普及,大体积混凝土基础及构筑体的部位逐渐增多。而大体积的混凝土施工技术要求比较高,特别在施工中要防止混凝土因水泥水化热引起的温度差产生温度应力裂缝等各种质量通病。因此需要从材料选择、技术保证措施等有关环节上做好充分的准备工作,才能保证大体积混凝土顺利施工。
With the development of industrialization and the gradual popularization of concrete use, the mass concrete foundation and the parts of structures gradually increase. The large volume of concrete construction technology requirements are relatively high, especially in the construction of concrete to prevent the temperature difference caused by the cement hydration heat stress cracks and other quality problems. Therefore, it is necessary to make adequate preparations from the material selection, technical assurance measures and other related links in order to ensure smooth construction of mass concrete.
