混凝土抗压强度计算的准确性问题，特别是对于成熟期大于28天的混凝土，在混凝土结构设计的某些计算中是有用的。MC 2010预标准和PN-EN 1992-1-1标准提供了计算fcm（t）的公式，包括材料比仅取决于水泥的强度等级。本文评估的准确性，这种方法的一个大的一套研究结果的不同水平的强度和水泥质量的混凝土的例子。
The issue of accuracy in calculation of concrete compressive strength, especially for a maturity period longer than 28 days, is useful in some calculations during designing concrete structures. The MC 2010 pre-standard and the PN-EN 1992-1-1 standard provide the equation for calculations of fcm(t) including material ratio is dependent only on the strength class of cement. The paper evaluates accuracy of this approach with the example of a large set of research results for concrete of varied level of strength and quality of cements.
