砖石工程冬季施工,我国习惯上采用掺盐砂浆砌筑,工程实践证明是成功的。然而,这种工艺在理论上还有待于系统总结,某些技术问题也需要有明确的解决。特别是许多年来我国地震灾害频繁发生,有的调研报告要求地震区砖石工程避免冬季施工。因此,定量地弄清掺盐砂浆的物理力学特性,冬季砌体的力学强度和抗地震能力,寻找配筋砖砌体中钢筋的防腐措施,并进而完善砖石工程冬季施工整套技术,显然是有必要的。
Masonry construction in winter, China used to use salt-mixed mortar masonry, engineering practice proved to be successful. However, this kind of craft still needs the systematic summary in the theory, some technical problems also need to have the clear solution. In particular, earthquake disasters have frequently occurred in China for many years. Some research reports require that masonry projects in earthquake areas be avoided in winter. Therefore, quantitatively understand the physical and mechanical properties of the salt-mixed mortar, the mechanical strength and seismic resistance of the masonry in winter, find the anti-corrosion measures for the steel reinforcement in the reinforced brick masonry, and further improve the whole construction technology of the masonry in winter, obviously Necessary.
