Mechanical Properties of High Strength Concrete Using Mineral Admixtures

Abstract:

This paper reports an investigation in which the performance of fly ash, blast furnace slag and silica fume high strength concretes were studied under 7 and 28 curing days. Three high strength concrete mixtures were made in this investigation. Mixtures containing 25% fly ash, 25% fly ash and 25% blast furnace slag, and 5% silica fume as cement replacement, respectively. The water-binder ratio of all the high strength concrete mixtures was kept constant at 0.34. The replacement of silica fume in the high strength concrete mixtures indicated higher value of the compressive strength, splitting tensile and modulus of elasticity. In addition, blast furnace slag is effective for strength and modulus of elasticity improvement between 7 to 28 curing days.
