The propertise of the compressive strength of ultra-high strength Steel Fiber Reinforced Cementitious Composites with mineral admixtures

광물질 혼화재를 사용한 초고강도 SFRCC의 특성

Silica fume has merits of filling the voids, enhancement of reheological chracteristics, prduction of secondary hydrates by pozzolanic reaction in reactive powder concretes. However silica fume has been imported in high-cost in domestic industry, we need to investigate replaceable material in stead of silica fume in a view of economy Therefore, in this paper, in order to investigation replacement of silica fume in ultra-high strength SFRCC we used another mineral admixtures like that fly-ash, blast slag.
