掺用粉煤灰和硅粉对混凝土性能影响的试验研究

Test Research on the Influence of Adding Fly Ash and Silicon Powder into Concrete on Its Character

原材料的选用关系到混凝土的各项性能指标,以适量的粉煤灰代替胶凝材料配制混凝土不仅降低成本,而且可以改善混凝土性能,文中以掺加不同掺量的粉煤灰和硅粉进行试验,得出对混凝土抗压强度和抗冲磨强度的影响,提供合理掺量,以供实际应用中参考。

Selecting the raw materials is related to the every characteristic index of concrete. Using a proper quantity of fly ash in lieu of cemented materials to make concrete not only can lower the concrete cost, but also can improve the concrete character. In this paper, the test of adding different amounts of fly ash and silicon powder was conducted, and the conclusion about the influence of adding admixtures on the compressive strength and anti-abrasion strength is presented; the reasonable additive quantity is put forward too.
