Abstract

Abstract: In order to study the uniaxial tensile mechanical properties of glass fiber textile mortar slabs, two groups of glass fiber textile mortar slabs of tensile were tested. The ordinary mortar matrix and the epoxy mortar matrix were used, respectively, which contained different glass fiber textile layers. Through tensile test of glass fiber textile reinforced mortar slabs, the failure process and failure mode were observed, and the influence of the number of layers of fiber textile, types of mortar and age on the tensile mechanical properties of the slabs was analyzed. The test results showed that the glass fiber textile can effectively improve the bearing capacity and deformation capacity of the specimens. The peak loads of ordinary mortar specimens with 1, 2, 3 and 4 layers were 16%, 107%, 211% and 357% higher than that without glass fiber textile. The peak loads of epoxy mortar specimens with 1, 2, 3 and 4 layers were 41%, 50%, 130% and 249% higher than that without glass fiber textile, respectively. The peak loads of slabs increased obviously with the increase of glass fiber textile layers. When the glass fiber textile layers were the same, the peak loads of epoxy mortar slabs and its corresponding deformation and ultimate deformation at failure were higher than that of ordinary mortar slabs. Compared with the specimens whose curing age was 28 days, the peak loads of ordinary mortar specimens reinforced with 1, 2, 3 and 4 fiber layers curing age 365 days increased by 34%, 37%, 29% and 7%, respectively. And compared with the specimens whose age was 28 days, the peak loads of epoxy mortar specimens with 1, 2, 3 and 4 fiber layers aged 365 days increased by 26%, 36%, 40% and 21%, respectively.
