    摘要：基于自燃煤矸石砂浆制作预制板的可行性，并应用到装配式钢结构内夹层楼板中，对单向楼板进行了板型设计，制作了6种不同规格的自燃煤矸石砂浆单向楼板，测试各试件在集中荷载下的抗弯性能。试验结果表明：跨度为900 mm时，各试件在一定楼面活荷载条件下，均能满足使用要求；同时得出各种板件的适用范围和最大跨度。参照GB/T 30100—2013《建筑墙板试验方法》对试件的抗冲击性、抗渗透和不透水性进行了相关研究。

    Abstract：In this paper，based on the feasibility of making precast slab with the spontaneous combustion coal gangue mortar，and applying to the sandwich floor of prefabricated steel structure，6 kinds of spontaneous combustion coal gangue mortar one-way slabs were made. And one-way slab plate type design and related performance tests have been carried out. Test results show that when the test span is 900 mm，all the specimens can meet the using requirements under certain floor live load; and the range of application of the various plates and the maximum span is obtained. At the same time，the impact resistance，impermeability and water tightness of the specimens are studied according to the GB/T 30100—2013 "Testing methods for building wallboard".
