混凝土构造物外观质量病害分析

Analyses the Appearance Quality Fault of Concrete

主要针对混凝土构造物外观颜色的形成原因、主要影响因素和混凝土温度裂缝的种类、外部表现以及产生的原因进行浅要的分析与阐述.并从原材料质量、施工工艺、施工工序、施工措施、合理利用外加剂、外部环境约束条件等方面,以及混凝土在浇筑、养护、拆模等细部环节上给出相应的防治与控制措施,达到比较反映混凝土基色的混凝土构件良好的外观质量,即经济又美观而且耐久。

It has been analyzed and stated mainly on concrete structures, the reasons for the formation ot the appearance and the color, the main factors and types of concrete temperature cracks and the outside performance and corresponding reasons. The corresponding prevention and control measures have been given on the raw material quality, construction process, construction measures, reasonable use of admixture, constraint conditions of external environment, and the pouring, maintaining and form shipping of concrete in detail. It can form good appearance quality which can reflect concrete base color that is not only fine butalso durable.
