A review on utilization of plastic waste materials in bricks
Singh L.B et al. [7] were used plastic waste in the brick are compact disc (CD) and Plastic Bottles (PB) with sand has a specific gravity of 2.61 in a mix of 1:1.5 (sand: plastic). With CD plastic waste (1:1.5) could achieve 10.6 MPa compressive strength whereas in PB plastic waste (1:1.5) achieved 10.6 MPa.
