Concrete is the most popular and widely used construction material due to its relatively low cost, versatility, and adaptability. Recent past experiences show that the reinforced concrete (RC) structures deteriorating prior to the expected service life when exposing to aggressive chloride or carbonation-induced environments. This is because of the general assumption that if the strength criteria are satisfactory, the concrete would be sufficiently durable. This assumption does not take into account the variability in concrete resulting from the actual concreting practices, such as placement, consolidation, finishing, and curing. In other words, concrete in the specimens cast for compressive strength bear little resemblance to the concrete in the actual structure. This paper presents a detailed review on the developments that are taking place globally toward the performance-based specifications for achieving the long-term durability of RC structures. Also, based on the in-house experimental studies and available knowledge, a durability performance criterion is suggested for structures exposed to chloride or carbonation-induced environments toward enhancing the service life.

基于性能的混凝土耐久性规范综述

混凝土由于其相对较低的成本、多功能性和适应性而成为最受欢迎和广泛使用的建筑材料。最近的经验表明，当暴露于腐蚀性氯化物或碳化环境时，钢筋混凝土 (RC) 结构会在预期使用寿命之前恶化。这是因为一般假设，如果强度标准令人满意，混凝土将足够耐用。这一假设没有考虑到实际浇筑、固结、修整和固化等实际浇筑实践所导致的混凝土的可变性。换句话说，为抗压强度浇筑的试样中的混凝土与实际结构中的混凝土几乎没有相似之处。本文详细回顾了全球为实现 RC 结构的长期耐久性而制定的基于性能的规范的发展情况。此外，根据内部实验研究和现有知识，建议对暴露于氯化物或碳化诱导环境的结构采用耐久性性能标准，以提高使用寿命。
