Damage Constitutive Model of Recycled Aggregate Concrete under Uniaxial Compression
2026
Overview
The effects of carbonated aggregate and aggregate replacement ratio on the stress-strain behavior of recycled aggregate concrete (RAC) under uniaxial compression were studied, and based on Lemaitre's strain equivalence hypothesis and Weibull distribution, a damage constitutive model was proposed. The results showed that carbonated aggregate enhanced peak stress. As the aggregate replacement ratio increased, the slopes of both the ascending and descending sections of the stress-strain curve gradually decreased, resulting in reduced peak stresses and decreased material brittleness. The damage constitutive model modified using linear regression analysis could describe the stress-strain curves well. As the aggregate replacement ratio increased, the slope of the \"S\" curve representing the damage variable evolution law gradually slowed down, and the corresponding strain gradually increased when the damage variable was 1. Meanwhile, the shape of the \"parabola\" curve representing the damage variable evolution rate became wider, and its vertex gradually decreased. Keywords: accelerated carbonation; damage constitutive model; damage variable; evolution law; recycled aggregate concrete (RAC); stress-strain curve.
