抗拉强度,是混凝土的主要力学性質之一。在水利工程、道路、飞机場跑道和其它許多工程中,混凝土的抗拉强度成为主要的質量指标。例如,一切有抗裂性要求的建筑物(水工建筑物,管道,蓄水池以及位于侵蝕环境的結構等),無論在設計和施工时,都需要知道混凝土的抗拉强度;尤其是对于承受弯曲作用 Tensile strength, is one of the main mechanical properties of concrete. In hydraulic engineering, roads, airport runways and many other projects, the tensile strength of concrete becomes a major quality indicator. For example, all buildings that have crack resistance requirements (hydraulic structures, pipelines, reservoirs, and structures located in aggressive environments, etc.) need to know the tensile strength of concrete, both in design and construction; especially for Bear bending effect
