Ceramic waste as an efficient material for enhancing the fire resistance and mechanical properties of hardened Portland cement pastes

Utilization of industrial byproducts like ceramic waste (CW) for enhancing the microstructure and mechanical properties as well as the fire resistance of hardened ordinary Portland cement (OPC) pastes is the main goal of this research. Different cement blends were prepared by partial replacement of OPC with 5, 10 and 20 CW (mass%). Besides, the effect of addition of 0.05 and 0.1 (mass%) of carbon nano-tubes (CNTs) on the mechanical properties...
