浅析桥梁清水混凝土结构外观质量控制措施

Analysis on Appearance Quality Control Measures of Bridge Pale Gray Concrete Structure

北京雁栖湖生态发展示范区对外联络通道京密路工程,针对本工程的清水混凝土成型外观,进行了材料比选、市场调查、方案比选等施工技术措施,最终制定出一套有效的施工方案。从优化混凝土配合比开始,到模板选用,涂膜剂选取,浇筑过程控制,及后期养护都做出明确要求。

For the Beijing Yanqi Lake Ecological Development Demonstration Zone's external communication channel Jingmi Road Project,we have carried out construction technical measures such as material comparison,market survey,and scheme comparison for the appearance of pale gray concrete in this project,and finally formulated a set of effective construction plan.From the optimization of the concrete mix ratio,to the selection of formwork,the selection of coating agents,the control of the pouring process,and the subsequent maintenance,clear requirements have been made.
