On efficient ratio of sawdust and shavings in wood-cement composite

Wood-cement composite comprising sawdust, shavings, sodium silicate, and additive of aluminum sulfate were investigated experimentally. The compressive strength of this composite consisting of shavings only (0,22 MPa) and consisting only of sawdust (0,84 MPa) was determined. When the weight ratio of these components reached 0,2:0,8, the compressive strength increased to 1,76 MPa. This effect can be considered to improve technology utilizing waste timber to produce wood-cement materials for low-rise building.
