摘要
某大桥26#墩承台施工,采用低热水泥,并掺入矿物、粉煤灰、引气剂和高效减水剂,降低水化热,增强混凝土强度、耐久性;分层浇筑、铺设冷循环水管,增强混凝土散热能力,降低混凝土内部温度;在施工过程严格实行控温保温养护措施,进行实时温度监测,实现了大体积混凝土温度控制的信息化施工,为混凝土保温保湿养护提供依据,为同类工程提供参考价值。
The mass concrete construction of number 26 pile cap of the Bridge makes use of low heat cement,mixed with mineral,fly ash,air-entraining agent,and concrete water-reducer to cut down the hydration heat as well as enhance the concrete strength and durability.Reducing the internal temperature of the concrete by setting circulating cooling water pipes and stratified pouring.The implementing of strict temperature control,preservation measures and real-time dynamic temperature monitoring in the working process makes the information construction of mass concrete temperature control come true.The study provides reference to the heat and humidity preservation of concrete and other similar projects.
