HF粉煤灰与硅粉混凝土抗冲耐磨性能试验研究

HF Fly Ash and Silica Fume Concrete Abrasion Resistance Test

水工建筑物的溢洪道、泄洪洞等承受高速水流冲磨的部位,多采用抗冲磨混凝土,其中硅粉混凝土和HF粉煤灰混凝土应用广泛;对硅粉混凝土和HF粉煤灰混凝土的抗压、抗冻、抗渗、抗冲磨等性能进行试验研究,结果表明HF粉煤灰混凝土的抗冲磨性、施工和易性以及经济性优于硅粉混凝土。

In the spillway of the hydraulic structures and spillway tunnel bearing high-speed flow,resistant concrete is widely used.Silica fume concrete and HF fly ash concrete are also widely used.In this paper,a lot of research is done on silica fume concrete,HF fly ash concrete,the compressive strength,frost resistance,impermeability,abrasion resistant and other performance tests,the results show that HF fly ash concrete abrasion resistant,workability and economy are better than those of the silica fume concrete.
