建设部、国家建材总局和中国土木工程学会、中国建筑学会、中国硅酸盐学会于今年1月17～19日在北京联合召开“混凝土碱骨料反应学术讨论会”。到会的全国各地有关专家50余人,提出学术论文及资料19份30余篇。会上发言中列举了国内外碱骨料反应对混凝土工程损害的实例、碱骨料反应机理、预防方法和我国的现实问题,一致认为随着我国近年来不掺混合材的硅酸盐水泥产量不断增加,除水利工程外,一般土建工程也必须重视预防碱骨料反应问题。建设部许溶烈总工程师和林太珍副总工程师分别主持了开幕式和大会发言,国家建材总局曹辰副总工程师作了总结讲话,均表明对碱骨料反应问题的重视,表示要将碱骨料反应问题引入“八五”重点科研项目,今后要体现在有关规范中。据
The Ministry of Construction, the State Administration of Building Materials, the China Society of Civil Engineering, the Chinese Society of Architects, and the Chinese Institute of Silicates held the “Concrete Alkali Aggregate Reaction Symposium” in Beijing from January 17 to 19 this year. More than 50 experts from all parts of the country attended the conference, and presented more than 30 academic papers and materials. At the meeting, we cited examples of concrete aggregate damage caused by alkali-aggregate reactions at home and abroad, the reaction mechanism of alkali-aggregate materials, prevention methods, and practical problems in China. We all agreed that the production of Portland cement that is not blended with composite materials in recent years in China Increasingly, in addition to water conservancy projects, general civil works must also pay attention to preventing alkali-aggregate reaction problems. The Chief Engineer Xu Ronglie of the Ministry of Construction and the Deputy Chief Engineer Lin Taizhen presided over the opening ceremony and the general assembly respectively. The Deputy Chief Engineer of the State Administration of Building Materials, Cao Chen made a concluding speech, all of which showed the importance of the alkali-aggregate reaction and expressed that The material reaction issue was introduced into the “Eighth Five-Year Plan” key scientific research projects, which should be reflected in the relevant specifications in the future. according to
