| Summary: | The construction sector is a significant contributor to greenhouse gas emissions that
contribute to global warming. Therefore, utilizing ‘green and recycled by-products’ in
construction is a measure towards a sustainable future. Coal Bottom Ash (CBA) generated
from thermal power plants has increases in production. This causes disposal problems.
However, due to the ongoing depletion of natural limestone in cement production and
aggregate in construction, this material may be used as a recycled construction material. This
paper presents a comprehensive analysis of CBA’s physical and chemical properties and the
impact on the use of CBA as aggregate or cement. A small volume of CBA can substitute fine
aggregates without compromising the strength of the concrete. Further research remains to be
carried to explore the potential of this material in producing concrete with enhanced strength.
