低掺量粉煤灰在水泥混凝土路面中的研究与应用

Application and Research of Low-dosage Fly Ash in Cement Concrete Pavement

大量的试验证明,粉煤灰不仅可以改善混凝土的和易性,降低混凝土早期的水化温升,改善混凝土的界面结构,而且还可以使水泥混凝土在抗压、抗折、抗渗透及其抗盐冻性方面均高于普通混凝土。

Large number of tests have proved that fly ash not only can improve concrete＇s workability, reduce the early hydration temperature rising of concrete, improve the interface structure of concrete, but also can cause cement concrete＇s compression resistance, bending resistance, permeability resistance and salt-freezing resistance to be superior than ordinary cement concrete.
