UTILISING WASTE IRON POWDER IN MANUFACTURING OF CEMENT PCB40

Abstract

Cement is an important binder used in building construction, but cement processing causes a severe impact on the environment. Finding new environmentally friendly binders or reducing the amount of cement to ensure the technical requirements of the construction is a crucial task to reduce the environmental impact of the cement industry. Besides, the iron and steel industries also discharge a large amount of waste into the environment. In this study, wastes from the iron and steel industry and other industries are used to form Ferrock binder to partially replace cement. The Ferrock content used to replace cement PC40 ranges from 6% to 22% and is evaluated for compressive strength, water absorption, and morphology. The results show the Ferrock powder content is 12% to produce cement PCB40 with a compressive strength of 40 MPa. Water absorption is also in good agreement with the compressive strength.
