Durability of Mortar Containing Coal Bottom Ash as a Partial Cementitious Resource

Abstract: This research work focuses on the study of the durability of composite cements based on coal bottom ash powder produced by SONICHAR in Niger. After a physicochemical and environmental characterization of the coal bottom ash powder, mortar test specimens were made. In these specimens, 10%, 15% and 20% of cement were replaced by identical mass percentages of coal bottom ash powder. Durability studies focused on the determination of the chloride ions apparent diffusion coefficient, the measurement of the depth of… Show more

“…The original coal bottom ash was ground in a ball mill to achieve a fineness of 3976 cm 2 /g. This high value is partially due to the presence of intragranular porosity at the powder, as shown in Figure 14b [35].…”

“…However, in this study, the percentage of CFA to CBA is not investigated, and pond ash is regarded as a uniform homogenous material. Savadogo et al, (2020) studied the durability of cementitious mortar made from CBA powder from SONICHAR in Niger. Cylindrical samples of 40mm diameter and 60mm height were cast using different mixes, with varying amounts of CBA powder added to replace the binder, which was Portland Artificial Cement (CEM 1), and cured for 90 days in water saturated with lime.…”

“…Bottom oil shale ash (BOSA) comprises angular particles that vary in size from sand to gravel. These particles can be used as a source of aggregate in construction [ 15 , 16 , 17 , 18 ]. FOSA comprises finer particles with silt size.…”
