Potential raw materials from biofuel combustion and pulp and paper production waste for the cement industry
A comparative characteristic of fly ash formed during the combustion of raw materials of plant origin (peat, bark, sawdust, sewage sludge from the pulp and paper industry) is given. The paper evaluates the possibility of using fly ash as a mineral component for cement production, systematizes the qualitative characteristics of ash for subsequent recommendations on their use as additives to cement compositions. The established difference in the chemical composition of the ash species under consideration shows that various mixtures can be used in the composition to unify ash secondary materials as additives, which will contribute to the greening of the economy and the promised reduction of environmental stress.Author: A.B.
