摘要
对17组85个钢纤维与水泥砂浆粘结试件进行了拔出试验,分别研究了不同类型和强度的钢纤维与不同强度等级砂浆基体的粘结强度、粘结破坏时纤维的破坏形态与基体及纤维自身强度和形状的关系,同时比较了钢纤维形状和砂浆基体强度对粘结滑移曲线特征和粘结破坏能的影响.
The main objective of the present work is to study the bond slip characteristics between steel fiber and high strength mortar by experimental method. Several parameters were considered in this test such as the strength rank of the matrix, the type and the strength of steel fibers. The differences of the bond strength between different types of fibers and the same strength rank of matrix were analyzed. The same work was done on the bond strength between different strength ranks of matrix and the same type of steel fiber. The strength of steel fiber was taken into account. Further more, the characteristics of bond slip curves were studied together with the bond slip work of various steel fibers.
