The characteristics of water absorption of wood-cement composites were investigated, comparing with those of particle board. The results obtained are as follows: (1) The water absorption of wood-cement composites was smaller than that of particle board. But up to about ten hours the water absorption of wood-cement composites was larger than that of particle board. (2) The coefficient of thickness swelling of wood-cement composites was 1/2〜1/3 of particle board. The reasons why that of wood-cement composites was small, are considered as follows: (1) The wood content of wood-cement composites is smaller than that of particle board. (2) The pressure intensity of pressing for making wood-cement composites is lower than that for making particle board. (3) On absorbing water, the recovering force of compressive strain in wood-cement composites is smaller than that of particle board, because the wood moisture content of wood-cement composites is high at the time of making them. (3) OIL absorbing water, the bond durability between wood and cement is a little smaller than that between wood and synthetic resin adhesive such as phenolic resin adhesive.
