Development of new trends in green concrete technology by using secondary raw materials and waste materials
Original language description
Concrete is still the most commonly used building material in the world, so there is a need to look for possibilities to make its production less harmful to the environment. Nowadays, many secondary materials are used that can make this construction material more ecological. However, much of the waste material created in the production of green concrete continues to be produced in huge quantities. As these materials’ problematic incorporation into cement matrix is common, an example of problematic behaviour is their negative influence on the rheology of fresh concrete and on hardened composite. An example of this waste material is fluidised bed combustion fly ash, which, based on its pozzolanic properties, provides a good premise for its use in concrete as an active admixture. On the other hand, its chemical composition and morphology makes the use of this material more problematic. The use of fluidised bed combustion fly ash in cement composite production as an admixture is not currently common, but
