我队附属混凝土构件加工场,对于冬季生产的混凝土构件,以往共采用两种养护工艺。露天台座以生产厚度为120毫米的多孔楼板为主,1973年起试验成功了“热台面,薄膜罩蒸气养护工艺”,较合理地解决了寒冷地区开敞式露天台座的冬季施工问题(本刊1975年第6期已刊登)。这种养护工艺在罩内敷设了喷汽管,但由于台面温度偏低, Our team’s subsidiary concrete processing plant has used two kinds of curing techniques in the past for the production of concrete components in winter. The open-air pedestal is mainly made of perforated floor slabs with a thickness of 120 mm. Since 1973, it has successfully tested the “hot-surfaced, film-covered vapour curing process” and solved the winter construction problems of open-air terraces in cold regions reasonably. The sixth issue of 1975 has been published). This curing process has a sparging pipe inside the hood, but due to the low temperature of the mesa,
