Fundamental Properties of Concrete Block and Brick using Casting foundry Fly Ash ;;;
Until now, disposal of casting foundry fly ash generally depends on reclamation. This is the great loss from a point of view saving of resources and utilizing industrial wastes. Therefore, a study on the use of fly ash as a substitute material for construction is necessary in order to utilize industrial wastes, to reduce cost of production, to improve quality in producing concrete products, and to protect environment from pollution. In this study, concrete products(hollow concrete block and concrete brick) using casting foundry fly ash as a substitute materials for cement, are produced. And experiments are conducted based on Korean Industrial Standards. Finally, the used methods of casting foundry fly ash as a substitute materials in industry are presented.
