我国现行规范用28天标准抗压强度作为评定结构或构件中混凝土是否达到设计标号的依据。这种方法虽然简便可靠,但不能及时了解混凝土生产中的质量波动信息,因此,这种传统测强方法也就限制了对混凝土质量控制的作用。随着建筑工业和结构设计理论的发展,如果还用28天标准强度来评定和控制混凝土质量,就不能适应日益发展的现代化施工技术的
China’s current specification uses the 28-day standard compressive strength as the basis for assessing whether concrete in a structure or component meets the design label. Although this method is simple and reliable, it cannot timely understand the information of quality fluctuations in concrete production. Therefore, this traditional method of strength measurement also limits the effect on the quality control of concrete. With the development of the construction industry and structural design theory, if the 28-day standard strength is used to assess and control the concrete quality, it will not be able to adapt to the increasing development of modern construction technologies.
