摘要

About 20 million cubic meter used-timbers are discharged every year from demolished buildings, mainly wooden houses in Japan. The authors have carried out a study on recycling used timber as wood-chip concrete. The experiment was carried out as follows. First, the wood-chips were filled into a steel mold to achieve the desired packing ratio with a compressive stress of 0.5 approx 1.0 MPa. Then, the fresh cement paste was injected into hte mold to make the specimens. The densities of the wood-chip concrete in this case generally fall into the range of 920kg/m~3 to 1250kg/m~3. To evaluate the performance of the wood-chip concrete, bending strength, compressive strength, drying weight loss and shrinkage, thermal conductivity, and thermal expansion were tered.
