Environmental impact assessment of wood bio-concretes: Evaluation of the influence of different supplementary cementitious materials
Abstract
This study evaluates the environmental impacts of workable wood bio-concretes (WBC). The WBC is composed of wood shavings, Portland cement (CEM), and two Supplementary Cementitious Materials (SCMs): metakaolin (MK) and fly ash (FA). A Life Cycle Assessment (LCA) was performed on seven WBC mixtures containing different contents of SCMs. When the compressive strength was used as a functional unit, the mixture containing 40% MK and 10% FA achieved the lowest values in most impact categories. We concluded that the CEM replacement by SCMs is a promising strategy to reduce the environmental impacts of the WBC, especially the climate change impact. © 2020 Elsevier Ltd. Show more
