Serviceability and reinforcement of low content whisker in portland cement

Abstract

In order to explore the serviceability and reinforcement of CaCO₃ whisker in portland cement matrix, the durability of CaCO₃ whisker and effect of low whisker content(0%–4.0%) on the working performance and mechanical properties of portland cement were investigated. The experimental results show that CaCO₃ whiskers have a good stability and serviceability in cement, and should not significantly alter the rheological properties of the cement paste. The flexural and compressive strength of portland cement reinforced by CaCO₃ whiskers was increased by 33.3% and 12.83%, respectively.
