Effectiveness of fabricating high performance fiber reinforced cementitious composite (HPFRCC) using high volume steel slag powder

Abstract

In this work, a high performance fiber reinforced cementitious composite (HPFRCC) is fabricated using high volume steel slag powder as a supplementary cementing material. Two water to cementitious materials ratio (w/cm), 0.25 and 0.35 respectively, and four contents of steel slag, namely 0, 30%, 60%, and 80% (percentage of total cementitious materials), are considered. The basic mechanical properties, including compressive strength and flexural toughness of HPFRCC, have been tested. The test results show that when the water cement ratio is 0.25 and steel slag content is 80%, HPFRCC shows a better flexural toughness. This work shows that it is feasible to utilize steel slag to produce HPFRCC, which not only gains a high performance building material, but also reduces industrial waste products.
