The production of Portland cements with a reduced clinker content corresponds to the strategy of decarbonization of building materials, aimed at reducing the negative impact on the environment and climate changes. This direction of development of the cement industry requires the use of more mineral additives. The application of waste-derived materials as the main non-clinker component is promising. The advantage of using wet-handled coal bottom ash is its pozzolanic effect and high grindability, but the main disadvantage is increased moisture. The introduction of wet-handled coal bottom ash in the cement industry requires an integrated approach that covers aspects of technology, economics, and ecology. The article investigates the feasibility of using wet-handled coal bottom ash as an additive to binders in terms of environmental performance while ensuring the required strength indicators of Portland cement.
