1959年8月,南京热电厂工程进入施工高潮,主厂房、控制室、开关室及化学水处理室等工程全面开花。根据慣例,框架結构混凝土应該使用普通水泥,但当时現場都只有火山灰水泥而沒有普通水泥。国家要求发电的日期非常紧迫,又不可能等待普通水泥而中止施工。因此,能否在厂房框架結构混凝土中采用火山灰水泥就成为年底发电的重要关鍵。根据以往的經驗和有关资料的介紹,火山灰水泥最适用于水中、地下結构和蒸汽养护的預制构件,而 August 1959, Nanjing Thermal Power Plant Project into the climax of construction, the main plant, control room, switch room and chemical water treatment room and other projects in full bloom. Conventionally, normal concrete should be used for concrete with frame structure, but at that time only pozzolanic cement was used instead of ordinary cement. The date of the country’s request for electricity generation is very urgent and it is impossible to suspend the construction of ordinary cement. Therefore, the ability to use pozzolanic cement in the concrete of the factory frame structure has become an important key for power generation by the end of the year. Based on past experience and the introduction of relevant information, pozzolan cement is best suited for prefabricated components in water, subsurface structures and steam curing
