Sustainable Building Materials Based on Various Industrial Wastes

This book conducts on get riding of various wastes including two problematic waste materials, of cement kiln dust (CKD) and grated poly(styrene) (PS), and in the same time in order to produce lightweight bricks of proper properties suitable for construction applications. Variable portions of Portland cement, iron slag and crushed waste glass were mixed with the two main components (CKD and PS) to validate the optimum mechanical integrity of the proposed bricks. Mechanical and physical properties were investigated by measuring the compressive strength, density, porosity and water absorption of various samples of various compositions. The results of mechanical resistance confirmed that the suitable composite of optimum integrity was produced in case of mixing 5% iron slag, 10% Portland cement and 10% ground waste glass with 3% shredded PS waste relative to CKD. The obtained sustainable building materials has reached the recommended value for construction applications on external shielding and internal non-load-bearing walls according to the national and international standardizations.
