Investigation into Ghanaian Calcined Clay as Supplementary Cementitious Material.
The Ghanaian clay was calcined at temperatures of 600, 700, 800, 900, and 1000°C (1112, 1292, 1472, 1652, and 1832°F) in a laboratory furnace. The properties of the raw and calcined clay were characterized using thermal gravimetric analysis (TGA), 27Al and 29Si solid-state magic angle spinning nuclear magnetic resonance (SS MAS NMR), and Fourier transformed infrared (FTIR) spectroscopic techniques. Pozzolanic strength activity indexes (PSAIs) were determined by replacing portland cement with 20% of the calcined materials.
