A Study on the Properties of High Performance Concrete using High Flowable Cement

High-Belite cement had a better slump flow characteristics than type I cement and slag cement, and its varation of slump flow with time was also excellent. As the amount binder added was increased, the strength increased while material separation decreased. This phenomena was obvious when the amount of cement was abobe 500kg/$\textrm{m}^3$ . When the amount of cement and S/a were 516kg/$\textrm{m}^3$ and 52% respectively, the application strength of 600kg/$\textrm{m}^3$ was satisfied. Since, however, the aggreate size of 25mm was somewhat unsatisfactory, the characteristics of high performance concrete could be obtained by the addition of the viscosity-enhancing agent.
