养护工艺是混凝土结构形成及制品生产的重要环节之一。目前建筑业的混凝土养护主要有:自然养护和蒸汽养护,近年来,燃料和电热养护也得到开发应用。在混凝土制品养护中蒸汽养护约占70%,而较落后的花管式养护在蒸汽养护中更为普遍。由于采用不同的养护工艺,混凝土养护能耗量差异较大,据北京地区三十多家大、中型制品厂普查结果,蒸汽养护混凝土制品单方耗煤量平均差异在 Maintenance technology is one of the important links in the formation of concrete structures and production of products. At present, concrete curing in the construction industry mainly includes natural conservation and steam curing. In recent years, fuel and electric heat conservation have also been developed and applied. In the maintenance of concrete products, steam curing accounts for about 70%, while the relatively lax tube-type maintenance is more common in steam curing. Due to the adoption of different conservation techniques, the energy consumption of concrete curing varies greatly. According to the results of a survey conducted by more than 30 large and medium-sized product factories in Beijing, the average difference in coal consumption of steam curing concrete products is unilateral.
