摘要:
深超总 C 塔项目地下室为 3 层加地下 1 层夹层,最深为 19.5m,东侧和南侧相邻地铁。为降低地下室外墙渗漏,采用水泥基渗透结晶型防水自修复混凝土。介绍了水泥基渗透结晶型防水材料的自修复特点及应用流程,并对外墙裂缝的愈合情况进行了现场监测与分析,对防水自修复混凝土的应用效果进行评价和总结。

The basement of the Shenzhen Super Headquarters Base C Tower project consists of threefloors plus one mezzanine,with a maximum depth of 19.5m. Its eastern and southern sides are adjacentto subway lines. To mitigate leakage risks in the basement exterior walls, cement,based permeablecrystalline waterproof self,healing concrete was adopted. This paper outlines the self,healingcharacteristics and application procedures of capillarywaterproofing materials, and evaluates theeffectiveness of the self,healing concrete through on,site monitoring and analysis of crack repair in theexterior walls.
