Influence of particle sizes in homogenous and heterogeneous wood cement board properties made from acacia mangium / Azlan Seraila

Influenced of particle sizes in homogenous and heterogeneous wood
cement board properties made from Acacia mangium
Wood-cement board (WCB) IS a panel product that has the advantages of
Inorganic and organic materials However, the main problems affecting the
manufacture and use of WCB are the inhibitory effects of wood on the
setting of cement and the high specific gravity of the final product. This
paper examines the potential and the use of particle sizes used and board
layer that was use to facilitate the production of a WCB from Acacia
mangium Wood cement boards (WCB) were manufactured with
wood/cement (w/w) ratio of 1:3, target density IS 1300kg m 3 and AI 2 (SO.j)~~
and Na.) SiO.\ content as chemical additives is 3.0% Besides that, WCB
also manufactured with the layer (homogenous and heterogeneous) The
WCB were tested for static bending (MOR and MOE) properties in parallel
and perpendicular directions; internal bond (IB), thickness swelling (TS)
and water absorption (WA)
