试论抗压与抗折的辨证关系及综合值的概念

Study on contradictory relationship between compressive and bending srtength and conception of synthetic value

本文通过对全国多个民用机场干硬性混凝土抗压和抗折强度试验数据的收集整理,得出了干硬性混凝土抗压与抗折强度之间存在着对立的矛盾关系,而不是过去认为的线性正比关系。并对这种关系进行了深入的理论探讨分析。最后得出了干硬性混凝土抗压与抗折强度综合值的概念。提出了综合值在工程实践中极高的实用价值。

By collecting and analyzing for testing data of compressive and bending strength of concrete used in civilaviation airports all over the country,the author got the conclusion that there exist some contradictory relationship between compressive and bending strengthen which is different from that kind of directly proportional relationship. After thorough theory analysis, he put forward the conception of synthetic value of compressive and bending strength, which has very high applied value in engineering practice. 
