在乌兹别克斯坦的海外工程中，需要参考或使用乌兹别克斯坦相关混凝土规范，鉴于中乌两国规范之间存在差异，为了有助于理解乌兹别克斯坦规范中对混凝土的配制强度及强度等级等概念的规定，先从数理上对混凝土强度等级及配制强度的关系进行推导，然后介绍了两国规范对此的相关规定，进行横向对比，并着重对乌兹别克斯坦规范混凝土强度等级及配制强度的关系进行了解析。乌兹别克斯坦认为：乌兹别克斯坦混凝土标准对配制强度的规定本质上也是基于随机变量的正态分布，要求对混凝土强度等级应具有足够的保证率；混凝土配制强度与混凝土强度等级之间的计算公式在形式上与我国不同，但可以通过变换化为一致，其本质是一样的；指出乌兹别克斯坦相关机构对2个概念的理解和执行情况与我国有不同之处，需要引起注意。
在烏玆彆剋斯坦的海外工程中，需要參攷或使用烏玆彆剋斯坦相關混凝土規範，鑒于中烏兩國規範之間存在差異，為瞭有助于理解烏玆彆剋斯坦規範中對混凝土的配製彊度及彊度等級等概唸的規定，先從數理上對混凝土彊度等級及配製彊度的關繫進行推導，然後介紹瞭兩國規範對此的相關規定，進行橫嚮對比，併著重對烏玆彆剋斯坦規範混凝土彊度等級及配製彊度的關繫進行瞭解析。烏玆彆剋斯坦認為：烏玆彆剋斯坦混凝土標準對配製彊度的規定本質上也是基于隨機變量的正態分佈，要求對混凝土彊度等級應具有足夠的保證率；混凝土配製彊度與混凝土彊度等級之間的計算公式在形式上與我國不同，但可以通過變換化為一緻，其本質是一樣的；指齣烏玆彆剋斯坦相關機構對2箇概唸的理解和執行情況與我國有不同之處，需要引起註意。

During the construction of the overseas projects in Uzbekistan,relevant Uzbekistan concrete codes need to be referred to.However,there is some difference between Uzbekistan concrete codes and Chinese concrete codes.In the paper,the correlation between the concrete strength grade and the concrete preparation strength specified in Uzbekistan concrete codes is deduced mathematically,the regulations on the concrete strength grade and the concrete preparation strength specified in Uzbekistan concrete codes and those specified in Chinese concrete codes are presented and compared,and the correlation between the concrete strength grade and the concrete preparation strength are analyzed. Conclusions drawn are as follows:The specifications on the concrete preparation strength in Uzbekistan concrete codes are actually normal distribution based on random variables,which requires adequate guarantee rate for the concrete strength grade;The form of the conversion formula between the concrete preparation strength and the concrete strength grade provided in Uzbekistan concrete codes is different from that provided in Chinese concrete codes,but they can be converted into the same formula,because they are the same in nature;Relevant Uzbekistan organizations have different understanding on these two concepts from Chinese organizations and they also treat these two concepts differently,to which we should pay more attention.
