鞍钢恢复生产建设初期,混凝土与钢筋混凝土工程冬季施工,几乎全部采用暖棚法,少量的地下基础混凝土工程,采用蓄热法。从一九五四年开始,在苏联专家的指导下,广泛采用电流加热法和蒸气加热法,在一部分无筋混凝土中,采用过掺氯盐的冷混凝土。抗冻早强效果极为明显的碳酸钾外加 In the early stage of production and construction of Anshan Iron and Steel, the construction of concrete and reinforced concrete works in winter was almost entirely based on the warm shed method, and a small amount of underground concrete was used for the thermal storage method. From 1954 onwards, under the guidance of Soviet experts, the current heating method and steam heating method were widely used.
