Mechanical Performance and Compressive Behaviour of Plastic Waste–Based Brick under Horizontal and Vertical Loading Orientations
Bricks containing 20-50% plastic waste were tested under horizontal and vertical compression after 3, 7 and 10 days. Horizontal strength rose with plastic content, reaching 30.15 MPa for the 50% mix at day 10 versus 22.74 MPa for conventional brick. Vertical strength remained only 1.08-1.22 MPa, below the 2.48 MPa control. A composite orientation-sensitive index therefore selected the 40% mix as the better balance.
