汾河二库枢纽泄水建筑物高强抗冲磨混凝土试验研究

Experiment on High strength,Scour and Abrasion Resisting Concrete (For Water Release Structure,the Fenhe Reservoir Ⅱ)

抗冲磨混凝土中掺用硅粉,用以提高水泥石的抗冲磨强度;掺用粉煤灰,在很少降低混凝土抗压强度与抗冲磨强度的条件下,较大地减小抗冲磨混凝土的干缩变形和温升,使抗冲磨混凝土性能有很大的改善。山西尖山铁矿石的应用为今后黄河中、上游新建大。

In this experiment,the selection of primary materials(such as cement,admixtures and aggregates,fine and coarse),the comparison test of the concrete and mix proportion are included.The basic mix proportion of the high strength,scour and abrasion resisting concrete offered has been adopted by the Fenhe Reservoir Ⅱ under construction.
