补偿收缩防裂混凝土在水库堆石坝面板中的应用

Application of compensation,shrinkage and anti-crack concrete in the face slab of Shanxi Reservoir's rock-filled dam

堆石坝钢筋混凝土面板容易引起开裂 ,从而降低混凝土面板寿命。通过掺用防裂剂等来改善提高混凝土抗裂性能 ,控制混凝土拌和与浇筑质量 ,加强混凝土面板湿养护 。

? The reinforced concrete face slab of rock filled dam is easy to cractk,so the life of the concrete face slab will be shorten.Applying the anti crack additives to improve the anti crack performance of concrete,controlling the concrete's agitating and casting quality,strengthening the face slab's wet cure,these may reduce or avoid the occurrence of the cracks of face slab. 〔
