Strength and durability characteristics of high strength autociaved stone dust concrete

摘要

The present study focuses on the effect of using fine stone dust as cement replacement on the mechanical properties as well as durability characteristics in high strength concrete. The effects of curing the concrete by autoclaving are considered. In the proposed new mix, 30 percent of the OPC was replaced by fine stone dust having 95 percent purity of silica. The results of the study indicated that through autoclaving, high strength concrete can be produced using fine storne dust with improved strength and durability characteristics, over the normal steam-cured high strength mix in which cement is not partially replaced by fine stone dust.
