HF粉煤灰混凝土与普通混凝土抗冲耐磨性能试验研究

The experimental research on erosion and abrasion resistance properties of HF fly ash concrete and ordinary concrete

在依据水力冲刷原理和文丘里原理设计的材料抗冲磨机以及空蚀发生器上,研究了不同流速、不同含沙量水流条件下HF粉煤灰混凝土和普通C30混凝土抗冲耐磨和抗空蚀性能。试验结果表明HF粉煤灰混凝土及普通C30混凝土抗冲耐磨和抗空蚀性能随冲刷水流介质条件的变化而变化,以及具有较高抗压强度的HF粉煤灰混凝土抗冲耐磨和抗空蚀性能明显优于强度相对较低的C30普通混凝土这一事实。

Under the water flow conditions with different velocities and sand content, the properties of erosion and abrasion resistance and cavitation resistance of HF fly ash concrete and C30 ordinary concrete are researched on the mechanical device designed according to hydraulic scouring principle and Venturi tubes principle. The experimental results show that properties of the two kinds of concrete vary with the difference of velocities and sand content of water flow, and the properties of HF fly ash concrete with relatively higher compressive strength are obviously superior to those of C30 ordinary concrete.
