CO2-emission

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.

Nowadays conventional binding material for the construction sector is Portland cement. Portland cement consists mainly of high-energy intensive with a significant carbon footprint Portland cement clinker. Reduction of clinker content in binding materials becomes the utmost priority for scientists in the field, it is reflected in manufacturers’ Sustainability Road Maps.
