摘要
着重研究采用硅灰裹石法对于提高混凝土路用性能的影响。研究结果表明:硅灰裹石掺粉煤灰高性能道路混凝土抗折强度比双掺硅灰、粉煤灰高强度混凝土提高20%左右,脆度系数降低30%左右,耐磨性提高15%以上。此外。
The effect of coating aggregate surface with silica fume on improving the properties of road concrete is researched in this paper.The results show that the flexural strength of road concrete with coating aggregate surface with silica fume enhances 20%,brittleness coefficient decreases 30% and abrasion resistance increases 15% compared with concrete with adding silica fume It is discussed and analyzed the mechanism of enhancing the properties of road concrete with silica fume coated aggregate
