大体积混凝土表面保温保湿施工工艺研究

Construction Technology of Mass Concrete Surface Heat Preservation and Moisturizing

为了有效地解决构件尺寸临界于大体积混凝土与非大体积混凝土之间的混凝土施工问题,研究了大体积混凝土产生温度裂缝的原因,提出了"软包大模侧模保湿保温"的新施工方法。通过在浏阳水岸山城项目中的施工实践,证明该方法对控制混凝土的温度应力具有较明显效果,且该方法操作简单,投入少,具有较好的经济效益,值得实际推广。

In order to effectively solve the concrete construction problem of the critical component size between mass concrete and none mass concrete, studied the temperature crack reasons of mass concrete, and proposed novel construction methods of ＂soft bag big mold side thermal insulation and moisture preservation ＂. By the construction practice of Liuyang waterfront mountain city project, proves that the method has obvious effect to control concrete temperature stress, and it is simple, small investment and has significant economic benefits, worthy of the actual promotion.
