Abstract

In order to study whether different concrete aggregate sizes have certain effects on the mechanical properties of concrete, three specimens with different concrete aggregate sizes were scanned by low field nuclear magnetic resonance testing method after fatigue test loading in this paper. By testing the transverse relaxation time of the three specimens, i.e. T2 spectrum, and NMR imaging, it is found that the test data of the three specimens are different and show some regular changes. Through further testing and analysis, it is concluded that different concrete aggregate size has certain influence on the mechanical properties of concrete. This result provides important help for scholars to study the size effect of concrete aggregate.
