| Abstract Scope |
This study evaluates the incorporation of industrial residues—iron ore tailings, red ceramic waste, and crushed sand—into soil-cement bricks for sustainable construction. Bricks were produced with up to 20% soil replacement and varying cement contents (6%, 8%, 10%), using manual pressing. Raw materials were characterized by particle size distribution, Atterberg limits, specific gravity, optimum moisture content, and X-ray diffraction (XRD). The bricks were tested for initial and total water absorption (13.8%–17.1%) and uniaxial compressive strength at 7 and 28 days. The best compressive strength exceeded 2.4 MPa, meeting NBR 8491 standards. Improved performance was associated with the filler effect and optimized particle packing, reducing porosity and increasing dry density. The results confirm the technical viability of using mineral and ceramic residues without compromising physical or mechanical behavior. This research contributes to the development of eco-efficient construction materials and reinforces the role of materials characterization in optimizing the structure–property–processing relationship. |
