Abstract
This paper presents the characterization of new lightweight cement composites incorporating limestone dust and charcoal. The charcoal is used not only to make the composite lighter in weight but also to improve its hygrothermal performance. Additionally, limestone dust, a waste material, is used instead of sand in the mixtures to improve their sustainability. Results show that the limestone-charcoal-cement composites have low thermal conductivity, while retaining good mechanical strength, high water vapor permeability, and low flammability. It was also found that these composites do not release dangerous substances in concentrations that jeopardize the safety of the environment or human health. Overall, the results suggest that the new limestone-charcoal-cement composites can be applied as lightweight screeds and other construction solutions, such as mortars or plasters that do not require high mechanical strength.Keywords
