摘要
混凝土建筑物耐久性不足,从短期效果而言,影响结构的外观及使用功能;从长远来看则会降低结构的可靠度,成为发生事故的隐患。混凝土的耐久性不仅要从组成材料的品质及混凝土本身的密实度着手,更重要的是把耐久性意识贯穿于设计、施工和使用过程之中,切实提高混凝土建筑物的耐久性,延长使用年限,提高经济效益。文章主要介绍了混凝土耐久性的现状、重要性以及影响混凝土耐久性的因素和提高混凝土耐久性的措施。
Concrete building＇s drability is not enough which can have an effect on structure＇s outside and function from short -term sight; it can also decline the Degree of reliability from long -term sight. We do increase the concrete structure＇ s drability and belong the life span , improve the economic benefit through focusing on the quality of the integrating materials and the concrete＇s density, applying the endurance sense into the process of designing, constructing and using. The article mainly introduced the current situation, importance, concerning factors of the concrete and the measures to increase the concrete＇s endurance.
