Coal Bottom Ash for Portland Cement Production

As shown in Figures 2, 3, and 4, the compressive strength of the mortar specimens at 28 days decreased gradually with increasing of coal bottom ash or fly bottom ash or mixes of them.. The mortars' early strength decreases when the ground coal bottom or fly ash content is over 10%. As expected, the coal bottom ash activity as well as the coal fly ash cement activity is lower at early ages.
