Experimental Research on Residual Strength of Recycled Aggregate Concrete under Compressive Fatigue Loading
To investigate the residual strength degradation of recycled aggregate concrete under fatigue loading, experiments were conducted to determine the functional relation between residual strength and the number of cycles. Fifty 100mm ×100mm ×100mm specimens of recycled aggregate concrete were tested under uniaxial compressive fatigue loading. Based on probability distribution of the residual strength of concrete under fatigue loading, the P-R-N curves are obtained based on test data, the empirical expressions of the residual strength corresponding to the number of cycles were obtained. The curves can be used to predict the residual strength with reliability.
