The physico-chemical characteristics of various blended cement pastes are studied in presence of nanometakaolin (2, 4, 6 and 8%) and in absence and presence of some industrial wastes such as ground clay bricks, cement kiln dust and silica fume. These characteristics are investigated at different hydration times (1-180 days) via determination of the compressive strength, total porosity and chemically combined water content. In addition, the phase composition of the formed hydrates is investigated through X-ray diffraction analysis. The IR spectra of hardened cement pastes are also recorded. The results indicate that the presence of nanometakaolin accelerates the hydration of the pastes which exhibit higher compressive strength than the neat ordinary Portland cement, and improves some other characteristics of the different pastes.
