摘要：通过四点弯曲试验和拉伸试验研究了灰砂比、增强材料种类及布置方式对水泥砂浆薄板力学性能的影响。结果表明：增大灰砂比能提高试件的弯曲开裂荷载；缩小BFRP筋的筋网尺寸能提高试件的极限荷载；增大BFRP网格厚度能改善试件的拉伸能力；掺短切玄武岩纤维的BFRP网格增强试件的抗弯和抗拉能力较好，是FRP永久模板的优选方案。 Abstract: Through four-point bending test and tensile test, the effect of cement-sand ratio, reinforcement material type and layout method on the mechanical properties of cement mortar slab was studied. The results show that the increase of cement-sand ratio can enhence the bending cracking load of the specimen. Reducing the size of BFRP bar mesh can increase the ultimate load of the specimen. Increasing the thickness of the BFRP mesh can improve the tensile capacity of the specimen. The BFRP mesh reinforced specimen mixed with chopped basalt fiber has good flexural and tensile capacity, which is the preferred scheme of FRP permanent formwork.
