Abstract:Current research has revealed patterns of performance variation in concrete materials through aspects such as mix proportions and curing duration. However, systematic exploration of the mechanical properties of centrifugally accelerated prefabricated cement-based materials remains scarce. This study investigates the effects of centrifugal acceleration?on the compressive mechanical performance and crack evolution patterns of prefabricated cement matrices using centrifugal digital image correlation (DIC) technology, with a focus on key parameters including elastic modulus, Poisson’s ratio, and compressive strength. Experimental results demonstrate that particle migration driven by centrifugal forces significantly enhances material compactness, reaching optimal conditions at?a=60g where densification peaks. Under this acceleration, elastic modulus increased by 337%, Poisson’s ratio rose by 21.7%, and overall compressive strength improved by 26.8%. These parameters exhibit pronounced growth gradients along the specimen height. Furthermore, cracks predominantly exhibited tensile-splitting characteristics parallel to the loading direction. As centrifugal acceleration increased, the cement-based materials gradually transitioned toward a mixed shear and tensile-splitting failure mode, though tensile-splitting failure remained dominant.
