引用本文摘 要：介紹了港珠澳大橋澳門口岸管理區大型多層停車庫薄壁清水混凝土配制技術。通過建立新拌混凝土性能量化參數，試驗驗證了膠凝材料用量、水膠比、礦粉、外加劑等對清水混凝土性能的影響。根據確定的性能量化參數及試驗方法進行了薄壁結構清水混凝土性能配合比設計。驗證結果表明，所配置的清水混凝土均符合項目中對薄壁清水混凝土性能的要求。 Abstract: The preparation technology of thin-walled structure fair-faced concrete for Large multi-storey parking garage in Macao port management zone of Hongkong-Zhuhai-Macao bridge was introduced. The quantitative parameters of fresh concrete performance were established, and the effects of cementing material dosage, W/B, mineral powder and admixture on the performance of fair-faced concrete were tested. According to the determined performance quantification parameters and test methods, the performance mix design of thin-walled structure fair-faced concrete was carried out. On-site verification of the design mix ratio indicates that the results meet the requirements for the performance of thin-walled fair-faced concrete in the project.
