钢筋混凝土结构在设计及施工中,混凝土强度的大小,是一项重要的计量指标,它关系到结构物的安全度问题。但是在实际施工时,不同阶段对混凝土强度的数值及其含义和作用是不同的。本文根据目前执行的国家标准《钢筋混凝土结构设计规范》 In the design and construction of reinforced concrete structures, the strength of concrete is an important measurement indicator. It is related to the safety of structures. However, in actual construction, the values ​​of concrete strength at different stages and their meanings and effects are different. This article is based on the current implementation of the national standard “Code for Design of Reinforced Concrete Structures.”
