Description: Previous research conducted in the laboratory pointed out several hardwood species that were either superior, comparable, marginal, or unsuitable for manufacturing cement-excelsior board (CEB). In this study, 40 full-sized boards were manufactured in a commercial production facility with the following species: yellow-poplar, sweet gum, southern pine, and a sweetgum/southern pine mixture. The properties of hardwood CEB were evaluated and compared with those of standard southern pine CEB. Results indicate that CEB made with yellow-poplar has equal or better properties than southern pine CEB. However, CEB made with all sweetgum or 50 percent sweetgum/50 percent southern pine does not meet the requirement of bending strength.
