中文摘要：

通过将自燃煤矸石破碎筛分得到粒径3mm以下连续级配的人工砂，探索使用不同添加剂及掺和料配制砂浆，测试其和易性、表观密度及强度，综合各项性能优选配合比制备墙板试件，进行保温隔声性能测试。结果表明，使用自燃煤矸石人工砂砂浆可以制作出满足装配式钢结构住宅体系强度要求的轻质墙板，且该墙板的保温隔声性能基本满足要求。

英文摘要：

Artificial sand within 3 mm particle size and continuous grading is obtained by crushing and screening the sponta- neous combustion gangue,using the sand to confect the mortar with different additives and admixtures,testing its workability,appar- ent density and different age strength by experiment. Selecting an optimal mix proportion to make wall specimen considering vari- ous performances and carry out test with its heat conduction performance and sound insulation performance. The experimental re- sults show that the feasibility of the artificial spontaneous combustion gangue mortar as the material of light wallboard with enough strength for the prefabricated steel building system was approved,and,the property index of heat conduction and sound insulation can meet the basie requirement.
