磷酸镁胶凝材料基体与玻璃纤维筋的粘结性能
Bond behavior of magnesium phosphate cement matrix and glass fiber bar
摘要
Abstract
Bond behaviors of magnesium phosphate cement (MPC) matrix with glass fiber bundle ( GFB) were investigated through measuring pullout force of GFB in MPC. The results show that the self-made inorganic adhesive can permeate into glass fibrils with markedly improved axial tensile strength of GFB. The pull-out force of GFB can be increased by mixing magnesium oxide powder. The micro structure of MPC paste is compacted by water glass to achieve pull-out force of GFB. The pull-out force can be effectively improved by the increasing of GFB length and MPC age. It can be confirmed that the optimized embedded length of GFB would exist and the maximum pull-out forces could be achieved in pullout destructive form. The pull-out force of GFB in MPC matrix with optimized embedded length is greater than that in epoxy resin matrix.关键词
