Abstract: Based on the concrete design logic of the densified mixture design algorithm (DMDA),this paper investigated aggregates with different densities,i.e.,aggregates sintered by using a reservoir's waste sludge,natural aggregates (stones),and aggregates of solid steel balls,whose aggregate densities are 1.7,2.6,and 7.8 kg·m^-3,respectively.Through the DMDA accumulation,lightweight,normal weight,and heavyweight high-performance concrete materials as well as their mixing ratios were obtained.The characteristics of these aggregate concretes,including the mixture properties and the effect of hardening behavior,were compared and analyzed.
