重庆建筑工程学院和四川省永荣矿务局共同对煤矸石中发热量极低的砂质矸石,用它代砂生产加气混凝土作了探索性的研究。在实验室条件下进行小模(15×15×15cm)试验。以砂质矸石、沸腾炉渣或自配沸渣水泥和生石灰为原料,通过试验得到几种配合比(重量%)如下:砂矸:沸渣:石灰=31.5:31.5:37,水料比0.60时,绝干容重900kg/m~3,出釜 Chongqing Institute of Civil Engineering and Engineering and Sichuan Yongrong Coal Mining Bureau jointly conducted an exploratory study on sandstone vermiculite with extremely low calorific value in coal gangue and used it to produce aerated concrete on behalf of sand. A small mold (15 x 15 x 15 cm) test was performed under laboratory conditions. Using sand vermiculite, boiling slag or self-allocated slag cement and quicklime as raw materials, several mix ratios (wt%) were obtained through the following tests: Sand slag: boiling slag: lime = 31.5:31.5:37, water ratio 0.60 , absolutely dry bulk density 900kg/m~3, out of the kettle
