A concrete sidewalk is considered heterogeneous because it is composed of different materials, including cement, water, aggregates (such as sand and gravel), and often additives. These components do not blend into a uniform composition at the microscopic level; instead, they retain distinct properties and textures. Additionally, variations in the mixing process and the presence of air pockets or imperfections can further contribute to its heterogeneous nature. As a result, the sidewalk exhibits variations in strength, texture, and appearance.
