Representative limestone samples have been collected to represent the Triassic, Jurassic, Cretaceous, Eocene and Oligocene ages. The limestone samples have been characterized for their microstructure, mineral and chemical composition, physico-mechanical characteristics, thermal behavior using polarizing and scanning microscopes together with X-ray micro-tomography, XRD-IR, XRF, Archimedes and Mercury intrusion methods and DTA-TGA, respectively. Post characterization, the samples were fired in electrical muffle furnace for calcination under the firing conditions (800℃ to 1100℃) for (0.25 – 2 h). Then the lime grains have been characterized for their hydration rate, free lime content, pore-distribution and microfabric.展开更多
