Influences of various particle sizes of coal bottom ash as supplementary cementitious material on the pozzolanic properties

The development of the world population shows a similar upward trend in the use of cement in the construction sector and rising tendency in the production of cement. These two occurrences considerably promote rise in the production of greenhouse gas (carbon dioxide) emission levels and coal ash from...
