Evaluation of the properties of wood sawdust-cement perforated blocks

In order to study the optimum manufacturing conditions of wood sawdust-cement perforated blocks, sawdust of headrige saw was mixed with portland cement type II, and then perforated blocks were molded from this mixture. The mixture ratios of sawdust to cement were selected as 28:72, 35:65 and 42:58,...
