英文
graded sand and stone-
In this paper, the effects of fly ash, cement, lime, fine sands, foam agent, w / c ratio and additional agent on foamed concrete were studied by experiments, the best combination ratio of fly ash foamed concrete whose density varies from 551kg / m3 to 650kg / m3 was obtained through orthogonal test design, the foam agent quantity and the fly ash quantity effect the fly ash foamed concrete greatly, so the author selected them as independents to establish duality linear regression equations, the equations were quite ideal through the test of model summary r. moreover, the author also did some experiments about the water resistance of magnesium oxychloride cement fly ash foamed concrete, the outcome showed that phosphoric acid has good effect on water resistance, and its appropriate quantity was found
本文通過試驗研究了粉煤灰、水泥、石灰、細砂、發泡液、水灰比及外加劑對粉煤灰發泡混凝土性能的影響,採用正交設計試驗方法得出了600級粉煤灰發泡混凝土的最佳配合比,同時發現發泡液和粉煤灰摻量對發泡混凝土的影響最為顯著,因此,以二者為自變量建立了二元線性回歸方程,通過全相關系數的檢驗發現方程較為理想。此外,還對氯氧鎂水泥基粉煤灰發泡混凝土的耐水性進行了相關實驗,發現磷酸有較好的耐水性效果,同時找到了其合適的摻量范圍。The cushion layer for the dam is constructed with the material prepared mainly with natural sandy gravel and mixed with proper amount of pebble and coarse sand
