Cover Story: Combining eco-sustainability and technological efficiency is one of the “hot” topics in the current construction and architectural sectors. In this work, recycled tire rubber aggregates and acoustically effective fractal cavities were combined in the design, modeling, and characterization of lightweight concrete hollow bricks. Fractal cavities improve the mechanical strength of the brick, its structural efficiency, and noise damping. The use of waste rubber as a total concrete aggregate represents an eco-friendlier solution than ordinary cementitious mix, providing, at the same time, enhanced lightweight properties, mechanical ductility, and better sound attenuation. The near compliance of rubberized blocks with technical requirements demonstrated good potential for incorporating waste rubber as aggregate for non-structural applications. View this paper
