Influence of Al-W-B Recycled Composite Material on the Properties of High Performance Concrete

Abstract The aim of this study is to obtain high performance boron containing material with sufficient carrying capacity with increased porosity and lower density at the same time. The influence of the different concentrations of Al-W-B powder on the properties of the fresh and hardened HPC was investigated. In the concrete mix design, the allite containing White Portland cement CEM I 52,5 R, granite stone, sand, microsilica, on polycarboxylates based super plasticizer and Al-W-B powder were used. As a source of boron composite material (CM), previously grinded powder containing boron-tungsten fiber and aluminium matrix (CM Al-W-B) was used. Grinding was used for processing of CM Al-W-B powder.
