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,对硅灰裹石法提高混凝土路用性能的机理进行了探讨 Emphasis was placed on the study of the effect of using silica fume stone on the road performance of concrete. The research results show that the flexural strength of the high-performance road concrete with silica fume and fly ash is increased by about 20% compared with the high-strength concrete with silica fume and fly ash, the brittleness coefficient is reduced by about 30%, and the wear resistance is improved by 15%. the above. In addition, the mechanism of improving the road performance of concrete with silica fume stone is discussed.
