HF高强耐磨粉煤灰混凝土在黄河大峡水电站工程的应用

HF Coal Ash Concrete with High Strength and Abrasion Resistance Used in Daxia Hydropower Station on Yellow River

ＨＦ高强耐磨粉煤灰混凝土具有水泥用是低，抗拉强度高，抗冲耐磨性能优质的特点，因此，极产产生裂缝。适用于闸墩及高速水流层混凝土，在钢筋密集的结件使用亦能保证施工质量，文中介绍了ＨＦ高强耐磨混凝土的性能及在大峡水电站预应力闸墩施工中使用情况。

The HF coal ash concrete has the features of high tensile strength, high resistance to abrasion and small quantity of cement use. It seldom cracks when used,therefore,the material is suitable for construction of gate piers and high speed overflow structures. It may ensure the quality of construction when the components with high density of reinforced steels. In this paper, the performance of HF coal ash concrete and its use in pre-stressed gate piers of Daxia Hydropower Station are expounded.
