摘要
介绍了中国妇女儿童博物馆地下工程混凝土的裂缝控制技术,通过方案的对比及论证,最终确定混凝土采用60d强度评定标准,在配比上加大掺合料用量,不采用膨胀剂,采用部分粒化高炉磨细矿渣粉,并在施工中采取切实、有效的"跳仓法"工艺,使工程质量达到了高标准。
Concrete cracks control technology for underground engineering in the Chinese museum of women and children is introduced.Through the comparison and demonstration of the scheme,it is finally confirmed that 60 days concrete strength evaluation standard is used,the amount of admixtures in mix proportion is increased,the expansive agent is cancelled,the partial ground granulated blast furnace slag powder is used and the process of pouring by separate strips is taken during the construction to make the engineering quality become high level.
