摘要
通过试验,测试了水胶比、粉煤灰掺量发生变化时,混凝土的限制膨胀率,研究了水胶比、粉煤灰掺量对限制膨胀率的影响变化规律。试验结果表明:在其他条件不变时,混凝土水胶比越大,限制膨胀率越小;掺入粉煤灰后,混凝土的限制膨胀率明显降低。
By way of the experiment,the restrained-expansion rates of concrete with different water-binder ratio and fly ash were tested,and the change rule of restrained-expansion rates was studied.The results indicate:the more the water-binder ratio,the smaller the restrained-expansion rate;the restrained-expansion rate decreased apparently when added fly ash.
