The authors of the article assessed the impact of operating fluids used to service aircraft on changing mechanical parameters of cement concrete intended for airport pavement. The research concerned concrete designed with the use of CEM I 42.5N LH NA low-alkali cement, broken granite aggregate, fine washed aggregate, and admixtures. The analysis included the assessment of changes in differences in endurance parameters over various research periods of up to 140 days. The obtained results allowed to carry out statistical analysis using the student's T-test. Research has shown a significant impact of operational fluids used in aircraft on the surface concrete properties of the airport. A reduction in the compressive strength of concrete exposed to one of the tested operating liquid to a reduction of 7.2% was observed over a period of 140 days, while there was no significant impact of operating fluids on tensile strength at splitting.
该文章的作者评估了用于飞机维护的操作液对机场跑道水泥混凝土力学参数变化的影响。研究涉及使用CEM I 42.5N LH NA低碱水泥、破碎花岗岩集料、细洗集料和外加剂设计的混凝土。分析包括评估长达140天的不同研究期间耐久性参数差异的变化。所得结果允许使用学生t检验进行统计分析。研究表明，飞机使用的操作液对机场表面混凝土性能有显著影响。在140天的时间里，观察到暴露于其中一种测试操作液的混凝土抗压强度降低了7.2%，而操作液对劈裂抗拉强度没有显著影响。
