南水北调中线干线工程混凝土碱骨料反应预防与控制

南水北调中线干线工程施工战线长，骨料料场分散，工程所用骨料、水泥等原材料种类繁多，工程沿线属我国活性骨料广泛分布区域，为了预防和控制碱骨料反应给混凝土工程带来的危害，对中线干线工程碱骨料反应试验方法判定标准、控制和预防措施等进行规范，较好地控制了混凝土碱骨料反应。

Control Measures of Concrete Alkali Aggregate Reaction in the Middle Route of the South-to-North Water Transfer

The Middle Route of the South-to-North Water Transfer has wide construction areas with dispersive aggregate sources, a great variety of materials such as skeletal material, cement and so on and wide distribution of active aggregate along the project. To control the alkali aggregate reaction, the paper introduces the test method of alkali aggregate, the standards of differentiating and control measures.
