本刊讯近日,由中国建筑工程总公司所属中建西部建设编写完成的“负温条件下商品混凝土施工工法”经鉴定,达到国内领先水平。该工法可有效解决混凝土行业冬季施工的诸多难题。该工法包含了负温条件下生产施工用混凝土原材料处理、施工工艺、热工计算、混凝土生产施工养护等工序,在加入普通防冻剂的同时,适量掺加引气剂、新型聚羧酸系高

Recently, by the China Construction Engineering Corporation owned construction in the western part of the completion of the preparation “under the conditions of commodity temperature concrete construction method ” by the identification, reached the leading domestic level. The method can effectively solve many problems in winter construction of concrete industry. The method includes the processes of raw material processing, construction technology, thermal calculation and concrete construction and maintenance during the production of concrete under the condition of negative temperature. When ordinary antifreeze is added, appropriate amount of air entraining agent and new type of polycarboxylic acid are added
