复合硅酸盐水泥混凝土中粉煤灰最优掺量的研究

Study of experimental the optimal amount of fly ash in composite cement concrete

在复合硅酸盐水泥混凝土中掺入粉煤灰,测试混凝土的施工性能、各龄期强度与抗渗性能。试验结果表明:粉煤灰掺量为15%时,复合硅酸盐水泥混凝土的和易性最好,28 d强度最高且抗渗性能最好。

Fly ash was mixed in the composite portland cement concrete, and the workability of concrete, the age strength and imperme- ability were tested.The test results showed that, the amount of fly ash was 15%, composite Portland cement concrete workability was best, 28 d strength was highest and impermeability was best.
