对注浆法制备的陶粒泡沫混凝土,采用正交试验方法,分析水胶比、粉煤灰掺量和泡沫掺量等对泡沫浆体填充效果的影响,获得填充效果各因素的敏感性排列顺序。结果表明:影响陶粒泡沫混凝土试件均匀性的顺序为:粉煤灰掺量>泡沫掺量>水胶比;影响7 d和28 d抗压强度的顺序为:泡沫掺量>粉煤灰掺量>水胶比。基于这种制备方法,提出了陶粒泡沫混凝土均匀性最优的推荐配合比。
For the ceramic foam concrete prepared by the grouting method, the influence of the water-cement ratio, the fly ash content and the foam content on the filling effect of the foam slurry was analyzed by orthogonal test to obtain the sensitivity of each factor order. The results show that the order of the homogeneity of ceramsite foam concrete specimen is: the content of fly ash> the content of foam> the ratio of water to binder; the order of compressive strength of 7 d and 28 d is foam content> fly ash Dosage> water glue ratio. Based on this preparation method, the optimal mix proportion of ceramsite foam concrete is proposed.
