关于使用硅粉混凝土进行桥面铺装的探讨

叙述了在混凝土中掺加硅粉,结合应用高效复合减水剂,不仅能减少单位水泥用量,而且可赋予混凝土较高的抗渗性能,掺加硅粉还可使混凝土强度对生产过程中变异因素敏感性降低,强度波动范围受到有效控制,结合工地实际情况,探讨了在桥面铺装混凝土中添加硅粉的可行性,并通过具体实验数据证明其合理性。

On exploration of bridge pavement construction with silica fume concrete

The paper indicates the mixture of silica in the concrete,by combining with the application of the high performance water-reducer,the paper indicates that it can not only reduce the concrete amount,but also make the concrete have better impermeability,illustrates the mixture with the silica fume concrete can lower the sensibility of variability factor of the concrete strength in the production process and the strength fluctuation scope will be controlled effectively,and explores the feasibility of the mixture of silica fume concrete in the concrete of the bridge pavement construction,and proves that the method is reasonable.
