This paper deals with the reuse of used timber as wood-chip concrete which is made by injecting cement paste into the void of compacted wood-chip. It will be finding that a valuable building material could be made by the method developed by the authors. 

Table 3 shows the test plan of wood-chip concrete. Fresh cement paste for injection was mixed by the double mixing method. The primary mixing water cement ratio was 0.23 and the chemical admixture was added to the primary water.
