约束裂缝 meaning in English
restraint crack
Examples
- Method of test for drying shrinkage cracking of restricted concrete
约束裂缝混凝土的干燥收断裂缝的试验方法 - Steel fiber scatters stress converging in the area of the top end of tiny cracks , restrict the occurrence and development of cracks , diminishes the width of cracks , and enhances the integrity of concrete with the occurrence of cracks via the effect of felting between concrete and steel fiber , and consequently the strength of concrete that resists compression , tension , and shear force increases obviously , and the capability of concrete that resists compact , and fatigue , and the ductility and durability of fissured concrete improve
钢纤维削弱了混凝土微裂缝尖端的应力集中、限制并约束裂缝的产生和开展、减小裂缝宽度、尤其是通过粘结作用提高了裂后混凝土的整体性，从而使混凝土的抗拉、抗弯、抗剪强度显著提高，其抗冲击、抗疲劳、裂后韧性和耐久性也有较大程度的改善。
