27、优先选用硅酸盐水泥和普通硅酸盐水泥，水泥标号不应低于今 42.5，最小水泥用量不应少于300KG/m3，水灰比不应大于0.6水：水泥（包括外掺混合料），并严格控制砼坍落度。为避免达到坑冻临界强度前受冻破坏，要求砼经运输到达现场温度不低于15，经泵送入模后温度不低于10，因此应会合搅拌站以研究采用可行的运输路线，并应有多种方案配合，以防因出现交通堵塞或者恶劣天气而中断砼和供应。砼运输过程中为防止热量损失过快，应对砼罐体采取保温措施。（4）、砼浇筑：砼在浇筑前应清除模板和钢筋上的冰霜，雪和污垢。砼送至浇筑部位后，应采取快布料、快振捣、及时覆盖保温，覆盖应均匀，尤其是边角、接茬部位要严密、压实、覆盖

28、完毕，设专人认真检查，遇有大风天气，留专人值班多次检查保温、覆盖情况，如有被风掀起时及时恢复压牢。楼板砼浇筑完后应用木抺搓压表面2-3 遍，最后一遍抺压要掌握好时间以终凝前为准，可用手按压法控制，然后再进行覆盖保温养护。（5）、砼保温养护措施：1、保温层在砼强度达到要求临界强度（4MPa）并已冷却到 5后方可拆除，拆模时砼温度与环境温差大于20时，拆模后的砼表面应及时覆盖保温，使其缓慢冷却，以防止温差过大引起的收宿裂纹。2、板保温：楼板支模均采用多层胶板板底模（厚度18mm）,其保温性能比较好，砼表面采用一层塑料薄膜加阻燃草帘被保温。顶板砼|精.|品.|可.|编.|辑.|学.|习.|资.|料.
