某体育场基础大体积混凝土施工温度控制技术

Temperature control technology for construction of mass concrete in one stadium foundation

以非洲某体育场拱脚基础大体积混凝土施工为例,从施工工艺及原材料选择、配合比优化、循环水降温等方面介绍了大体积混凝土施工期温度控制技术,实践表明:采用循环水降温的方法可以有效控制大体积混凝土施工期内部温度和内外温差。

he paper uses a mass concrete construction of a basis of arch foot in one stadium as an example. It introduces the control technology of mass concrete temperature during construction by the way of construction process and raw materials selection, mix optimization, cooling concrete by circulating water, etc. Practice shows that use of recycled water for cooling concrete can be effective control the internal temperature and temperature difference between inside and outside of mass concrete in construction period.
