摘要:

In order to master the mechanical troughness the alkali-resistant bundling glass-fiber reinforced concrete, the axial tensile, four-point bending toughness and three-point incision beam fracture tests were carried out, respectively, on the alkali-resistant bundling glass-fiber reinforced concrete. The steel fiber concrete and the crude polyolefin fiber concrete had volume fractions of 0.45% and 0.75%, respectively. The influence of fiber fraction on the mechanical properties of the alkali-resistant bundling glass-fiber reinforced concrete was analyzed and compared with the steel fiber concrete and crude polyolefin fiber concrete with the same volume fraction. Test results show that the axial tensile properties of the alkali-resistant bundling glass-fiber reinforced concrete is better than that of crude polyolefin fiber concrete with the same volume fraction; meanwhile, the tensile strength and ultimate tensile strain are slightly higher than that of the steel-fiber reinforced concrete with the same volume. When the alkali-resistant bundling glass fiber volume fraction is 0.75%, the flexural toughness value and peak intensity are 191.73% and 11.47% higher than that of plain concrete, respectively, and the fracture toughness and fracture energy are 28.16% and 268.69% higher than that of plain concrete, respectively. The flexural toughness and fracture mechanics index of the alkali-resistant bundling glass-fiber reinforced concrete has increased greatly with this volume fraction. © 2019, Editorial Department of Journal of HEU.
