Abstract There were investigating the effect of aluminium-tungsten-boron (Al-W-B) powder as waste material, obtained from crashing and milling of Al-W-B composite material, to a high performance concrete (HPC) in order to obtain neutron absorbing material with sufficient carrying capacity but with increased porosity and decreased density concurrently. In order to evaluate the effects of Al-W-B powder to the concrete structure, HPC as a reference concrete was used. A mix design of HPC from the author's (1) previous research work was used. In this study, the influence of the Al-W-B powder in different dosages on the properties of fresh and hardened HPC was investigated. Specific minimum water/cement (W/C) ratio to each sample of HPC was applied to reach required flow ability properties of fresh concrete mixture. As source of boron composite material (CM), previously grinded powder containing boron-tungsten fibre and aluminium matrix (CM Al-W-B) is used. A method of grinding has been used for processing of CM Al-W-B powder.
