Study of Properties of Concrete with Mineral Materials of Gangue

Abstract:

Abstract. This research was to enhance strength and durability of concrete in both design and construction with gangue. Particularly, the strength and performance of concrete is achieved by optimizing the gangue, fly ash and silica fume replacement for cement. The gangue has been used as a cementitious material. The many technical benefits available to concrete user, such as reduced heat evolution, lower permeability and higher strength at later ages, in order to increase resistance to sulphate attack and alkali silica reaction. A number of recommendations are given for the effective use of gangue and fly ash in concrete. The results show that 10% gangue, 15% slag, 15% fly ash, 10% silica fume of replacement was found to be an optimum level and demonstrated excellent performance in concrete. The paper is intended to provide guidance for those concerned with the design, application and performance of concrete with gangue in practice where gangue can also help to reduce costs and energy demands in the production of concrete compared with conventional Portland cement concrete.
