中文摘要：

以混凝土满足和易性、强度的同时表观密度最小为目标,在保证混凝土强度达到墙板抗拉开裂最大强度的前提下,配制出一系列表观密度不大于900 kg/m~3超轻混凝土,并且探索特殊外加剂对混凝土的影响。通过15种配合比试验,得出最佳配合比。充分利用粉煤灰、煤矸石等工业废料,真正实现变废为宝。

英文摘要：

Concrete to meet and easy,strength and apparent density minimum as the goal,in ensure the concrete strength reach wallboard tensile cracking maximum strength under the premise prepared a series of table density not greater than 900kg/m3 lightweight concrete,and explores the special additives on the effect of mixed concrete.Through 15 kinds of mixture ratio test,the optimum mix ratio.Make full use of fly ash,coal gangue and other industrial wastes,truly turning waste into treasure.
