清水混凝土施工的质量缺陷与预控措施

清水混凝土目前在我国尚无明确的质量标准和规范，限于国内施工单位技术水平参差不齐，而且清水混凝土施工是一项非常细致的工作，比一般混凝土施工要求严格，因此极易出现质量缺陷。本文详细介绍了清水混凝土的质量标准及其施工中常见的质量缺陷，并从混凝土原材料控制、混凝土浇筑与养护；钢筋放样、绑扎；模板选型、拼接以及缺陷修复、成品保护等方面提出了可行的预控措施。

Defect and Pre-control Methods for Fair-faced Concrete Construction

At present, there is no definite quality standard for fair-faced concrete in civil engineering. Because the contractors are different in technique level and the fair-faced concrete construction is more complex than common concrete one and ease to cause defect. In this paper, the quality defect of fair-faced concrete is introduced and some pre-control methods from some aspects, including raw materials of concrete, casting, maintenance, steel bar cutting, formwork jointing treatment, defect mending, finished product protection and so on are presented.
