Mineral Admixtures : The Key To High Strength Concrete

Abstract

This paper presents the results of an experimental investigation for the reuse of some locally available industrial waste materials namely, granulated blast-furnace slag (BFS), pulverized fuel ash (PFA), limonite, and silica fume (SF) in producing high strength concrete. Developing of high strength concretes has a worth priority field of study worldwide, their production is largely expanded in the last two decades. Potential applications of high strength concrete are in producing thin durable sections and in strengthening and repairing defaulted structures. The principal engineering properties of the developed concretes such as compressive strength, modulus of rupture, and modulus of elasticity were investigated. .The test results revealed that the resulting concretes have excellent strength properties superior to those made of only ordinary Portland cement. The suggested utilization of these industrial waste materials provides a useful mean of disposal for a considerable amount of these solid wastes and contributes in the environmental protection.
