Abstract:In order to explore the serviceability and reinforcement of CaCO(3) whisker in portland cement matrix, the durability of CaCO(3) 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 CaCO(3) 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 CaCO(3) whiskers was increased by 33.3% and 12.83%, respectively.
