Abstract: Construction by-product timber reached an amount of 5 million-tons a year in association with demolition and construction of buildings. Aiming at reusing of the demolished timber, a wood-chip concrete has been developed and physico-chemical, mechanical and anti fire properties have been studied by the authors. Because it was manufactured by injecting cement paste into a space of pre-packed wood-tips in a mold, further productivity has been needed. In this study, a new manufacturing method that mixes wood-chip, cement and water together was proposed and bending and compressive strength as well as volume changes of the wood-chip concrete were examined. It was shown that the amount of the reused wood-chip was greater than before, and manufacture of partition walls and narrow-width panels was possible.
