This study focuses on the influence of biochar – a solid; porous; carbonaceous material product resulting from biomass gasification of wood waste – on mechanical properties of cement mortars. In order to investigate its effectiveness for structural purposes; biochar is added in cement mortar in increasing percentages; up to 2.5% by weight of cement. Experimental findings show that; by including a proper biochar percentage; compressive and flexural strengths comparable to those of control specimens are obtained; with a slight increase in fracture energy. The use of biochar in building materials as carbon sink is also part of a strategy for the development of more sustainable materials within the construction industry; since the dual aim of storing carbon in a stable form in buildings and promoting waste reutilization by increasing the recycling rate could be achieved. © 2020 Elsevier Ltd;
