The study reveals that good quality bricks can be produced from a slag–lime mixture and sand by pressing the mix at a pressure of 50 kg/cm 2 (4.9 MPa). Bricks of wet compressive strength in the range of 80–150 kg/cm 2 (7.85–14.7 MPa) have been obtained after 28 days of humid curing at ambient temperature. Production of slag-based bricks consumes less energy compared to conventional burnt clay bricks or calcium silicate bricks.
