鉴于天津、上海等地采用无压纯饱和蒸汽养护(以下简称无压蒸养)硅酸盐砌块取得了良好的效果,北京市钢筋混凝土构件厂在生产钢筋混凝土构件中也改有压蒸养为无压蒸养。经过半年来的生产实践证明,这种养护法具有如下优点:1.降低蒸汽耗用量。根据测定(表1),无压蒸养比有压蒸养(1—3—4—3小时,85℃)可节约蒸汽25%左右;如有压蒸养制度为1—4—5—4小时,85℃,则无压蒸养节约蒸汽可达52%。在相同
In view of the fact that Tianjin, Shanghai and other places have achieved good results in the use of pressureless pure saturated steam curing (hereinafter referred to as pressureless steaming) silicate blocks, the Beijing reinforced concrete component plant has also adopted pressure steam curing in the production of reinforced concrete components. For pressureless steaming. After six months of production practice has proved that this curing method has the following advantages: 1. Reduce steam consumption. According to the measurement (Table 1), pressureless steaming and steaming can save about 25% steam when compared with pressure steaming and steaming (1–3—4—3 hours, 85°C); if pressure steaming and steaming system is 1-4—5—4 Hours, 85 °C, the pressureless steaming and steaming up to 52%. In the same
