混凝土强度的验收标准直接影响到混凝土施工质量的控制与评定,对保证工程质量与工程的经济合理性具有重要作用。制订一套合理的验收标准,是一项较复杂的工作,它与结构安全度的设计要求、混凝土的施工配制强度和在施工管理工作中是否便于执行等多种因素有关。因此,至今还有许多问题尚在讨论之中。混凝土强度和许多随机变量一样也是波动的,其分布规律基本上符合于正态曲线分布。在此基础上人们用数理统计的方法,确定施工配制强度,制订验收标准。各国制订
Acceptance standards for concrete strength directly affect the control and evaluation of concrete construction quality, and play an important role in ensuring project quality and engineering economic rationality. The development of a reasonable set of acceptance criteria is a more complex task. It is related to various factors such as the design requirements for structural safety, the strength of concrete construction preparation, and whether it is easy to implement in construction management. Therefore, there are still many issues that are still under discussion. The strength of concrete, like many random variables, fluctuates, and its distribution pattern basically conforms to the distribution of normal curves. Based on this, people use mathematical statistics to determine the strength of construction preparation and formulate acceptance criteria. Developed by various countries
