Studies of Surface Area and Pore Structure on Portland Cement Produced in Bajil and Amran, Yemen
Portland cement pastes of various porosities were prepared using water/cement ratios of 0.30, 0.35, 0.40, 0.45, 0.50 and 0.55; and were hydrated for various time intervals ranging from 0.021 to 28 days. Pore structure and VL–t plots (plots of volume vs. thickness) of the hardened cement pastes were measured using nitro …
