Porosity and strength of PFA/SF/OPC ternary blended paste
The results presented in this paper form part of an investigation into the optimization of a ternary blended cementitious system based on ordinary Portland cement (OPC)/pulverized fuel ash (PFA)/silica fume (SF) for the development of high-performance concrete. Cement pastes covering a wide range of PFA/SF blending proportions were investigated. Compressive strength and porosity at the ages of 7, 28, and 90 days for cement paste specimens containing 0%, 15%, 20%, 25%, 30%, 35%, 40% and 45% PFA along with 0%, 5%, 10% and 15% SF as partial cement replacement at a water-binder ratio of 0.30 were investigated. A statistical approach was used which permitted the calculation of the isoresponse curves for the parameters under study over the experimental domain and the optimization of their effect.
