This study was carried out to explore the possibility of making cement-bonded composite building products using eucalypt (Eucalyptus camaldulensis) and poplar (Populus deltoides). The experimental design consisted of three treatments—mixture of fibrous materials, cement and calcium chloride (CaCl2) contents. Some physical properties, vis. water absorption (WA) and thickness swelling (TS), were investigated. The ratio of woodwool : cement was 40:60 and 60:40 by weight. Results showed that, water uptake increased with increasing woodwool content. In addition, boards fully made with poplar woodwools had superior properties compared to the eucalypt and mixed woodwools. The presence of eucalypt woodwools in mixture of fibrous materials typically resulted in increase in TS and WA. It is interesting to note that a dose of 5% of CaCl2 by weight of cement can enhance the effect of cement. Application of Duncan’s Multiple Range Test for the mean values of the results showed that the effects of all variables and their interactions on the mechanical properties in terms of TS and WA were highly significant.
