style="text-indent:25px">昆明混凝土公司哪家好？昆明泡沫混凝土廠</p><p style="text-indent:25px">泡沫混凝土是一種輕質的水泥基保溫材料，基本的原理就是使用混凝土中大量的氣孔而達到輕質，保溫和隔熱的效果，那么泡沫混凝土在澆筑以后多長時間可以繼續(xù)施工呢?下面就由永欣建材為大家進行以下講解。泡沫混凝土施工地下室回填土之前需要進行根底檢驗，根底檢驗就得檢驗報告，檢驗報告就得有混凝土的實驗報告，這些都是規(guī)范的一些程序，大約就能夠計算出回填土的時刻了。假如你有特殊的辦理，防水又做完了，做好防水維護就能夠回填土了。也能夠不走正常程序進行回填。1、通常是泡沫混凝土到達28天或到達規(guī)劃強度90%。2、基坑深度1——2米時可早點回填，側壓力較小。3、若達不到強度會呈現(xiàn)豎向裂縫。4、盡管到達強度在梁的下方還會呈現(xiàn)豎向剪力裂縫。昆明泡沫混凝土廠</p><p
