Study on the reaction degree of calcined coal gangue powder in blended cement by selective solution method
چکیده انگلیسی

Calcined coal gangue powder was used to partially replace Portland cement (PC) at 10%, 20%, 30%, and 40% by weight. The water to binder ratio (w/b) of 0.5 was used for all the blended cement paste mixes. The reaction degree of calcined coal gangue powder in calcined coal gangue powder/cement (AC) was determined using a selective dissolution method. It was found that high-volume calcined coal gangue powder pastes underwent a lower degree of reaction of calcined coal gangue powder. The effect of calcined coal gangue powder replacement on the reaction degree of calcined coal gangue powder in AC pastes in later age was less than that of in early age.
