However, it is considered low compressive, flexural and tensile strength compared to other types Due to the trend towards using sustainable materials to preserve the environment by getting rid of waste and decreasing the amount of carbon dioxide produced while manufacturing some concrete components by substituting with environmentally friendly materials.
Due to its properties, waste construction materials are increasingly used instead of aggregates in construction projects.
