Abstract:
In order to investigate the alkali resistance of basalt fiber mesh and glass fiber mesh and their influence on the biaxial bending properties of fiber textile reinforced concrete panel, the alkali resistance test of basalt fiber and glass fiber and the biaxial flexural properties of fiber textile reinforced concrete slab were carried out. Based on the two-way slab test in accordance with EFNARC, the biaxial effect of different fiber textile was analyzed. The results show that the corrosion resistance of alkali resistance glass fiber is superior to that of basalt fiber. The high two-way tensile properties of the fiber textile can improve the inner force redistribution and stress redistribution ability of the two-way slab. The incorporation of basalt fiber mesh and alkali-resistant glass fiber mesh improves the bending resistance load capacity of the concrete matrix slab by 48% and 59%, respectively. Besides, the bidirectional reinforcement of alkali-resistant glass fiber mesh is better than basalt fiber mesh.
