水泥的贮藏时间不能过长,因为水泥在存放时,水泥的颗粒和空气中的水蒸汽、二氧化碳发生作用,会受潮结块,降低这些颗粒的胶结能力,使水泥凝结时间延长,强度下降。硅酸盐水泥,在正常干燥环境中存放超过3个月,强度降低约10%;存放6个月,强度降低约20%,因此,水泥的存放时间不应超过3个月,如超过3个月,必须进行检验,重新确定水泥标号。水
Cement storage time can not be too long, because the cement in the storage, the cement particles and the air in the water vapor, carbon dioxide, will be agglomerated, reduce the binding capacity of these particles, so that the cement coagulation time, strength decreased. Portland cement, which has been stored for more than 3 months in a normal dry environment, has a strength reduction of about 10%; for 6 months, the strength is reduced by about 20%. Therefore, the storage time of cement should not exceed 3 months, if more than 3 Month, must carry on the inspection, redetermines the cement label. water
