电化学反应和应力腐蚀是 4 5Si2Cr预应力钢筋断裂的根本原因 ,钢材中夹杂物存在 ,拉应力不均匀和表面缺陷加速了应力腐蚀开裂的过程 ,文中提出了技术改进措施
Electrochemical reaction and stress corrosion are the root causes of 4 5Si2Cr prestressed steel bar breakage. The existence of inclusions in the steel, uneven tensile stress and surface defects accelerate the process of stress corrosion cracking. In this paper, the technical improvement measures
