实现薄灰缝设计是蒸压加气混凝土砌块砌体推广中的关键问题之一,为解决这一问题需要寻找一种抗拉强度高且厚度较薄的材料代替传统拉结钢筋,通过配玄武岩纤维格栅蒸压加气混凝土砌块砌体基本力学性能试验,研究了玄武岩纤维制品网格尺寸、断裂强度、铺设层数以及在纤维表面涂覆环氧树脂等因素对砌体基本力学性能的影响.结果表明:与普通砌体相比,配玄武岩纤维格栅砌体抗压强度增加约10％,抗剪强度增加约13％,砌块强度利用率提高8％左右.灰缝厚度为5mm,能实现薄灰缝的要求.%How to achieve thin mortar joint of autoclaved aerated concrete block confined masonry structure is one of the key problems for promotion,in order to solve this problem,it is necessary to find a kind of material with high tensile strength and thin thickness instead of traditional steel bars.In this paper,the basalt fiber grid is used as the confined masonry structures,and a series of test are carried out to research the basic mechanical properties of autoclaved aerated concrete block masonry.The effects of the mesh size,the fracture strength,the number of plies and the epoxy resin on the surface of the basalt fiber are studied.The results show that compared with the ordinary masonry,the compressive strength of basalt fiber reinforced concrete masonry is increased by about 10％,the shear strength is increased by about 13％,and the utilization ratio of the block strength is about 8％.The mortar joint thickness is 5mm,so it can meet the requirements of the design of thin seam grey.
