Initial study of Eucalyptus Wood Ash (EWA) as a mineral ... - Redalyc
Abstract: This study evaluated the possibility of using in natura Eucalyptus Wood Ash (EWA) from aviary furnaces as a mineral admixture in concrete. The ash was 100 mesh-sieved and added to the mix in 5, 10, 15 and 20% of the cement bulk. Physical analysis unveiled that EWA has a specific gravity higher than other organic originated residues, whereas its BET specific surface area is not enough ...

4. GLOBAL CARBON DIOXIDE EMISSIONS FROM CEMENT MAKING - Annual Reviews
Abstract The cement industry contributes about 5% to global anthropogenic CO 2 emissions, making the cement industry an important sector for CO 2-emission mitigation strategies.CO 2 is emitted from the calcination process of limestone, from combustion of fuels in the kiln, as well as from power generation. In this paper, we review the total CO 2 emissions from cement making, including process ...

Modeling of the Thermochemical Conversion of Biomass in Cement Rotary Kiln
Aranda et al. [ 8 ], in their study, have approximately given a ratio of 20% for biomass which may be substituted in cement rotary kiln, while maintaining a stable combustion process and the quality of the clinker. Hence there is a need for a better understanding of the thermochemical phenomena taking place in the kiln.
