对一些重要钢筋混凝土结构如何选择一种最优化的冬期施工工艺,是一个具有重要技术经济意义的问题。通过几年来的施工实践,我们认为“综合蓄热法”(即复合外加剂+蓄热和复合外加剂+蓄热+短时加热两种,以下简称本工艺)和其它几种传统的,单一的冬期施工工艺相比,具有节约能源、工艺简便、造价较低、适应性强等优点,在施工中取得完满的效果,八○年后开始在重要钢筋混凝土结构中试用,现在巳成为我公司冬期施工混凝土工程中一种普遍应用的施 How to select an optimal winter construction process for some important reinforced concrete structures is an issue of important technical and economic significance. Through several years of construction practice, we believe that “comprehensive heat storage method” (that is, compound admixture + heat storage and compound admixture + heat storage + short-time heating, hereinafter referred to as the process) and several other traditional, single Compared with the winter construction technology, it has the advantages of energy saving, simple process, low cost, and strong adaptability. It has achieved satisfactory results in construction and began to be used in important reinforced concrete structures after 1989. Now it has become our company. A commonly used application in winter construction concrete works
