Resumo(s): | An experimental preliminary investigation was conducted to evaluate bond strength between Ordinary Portland Cement concrete substrate and three repair materials. Tungsten mine waste geopolymeric binder and two commercial repair products were used as repair materials. This study indicates that tungsten mine waste geopolymeric binders possess much higher bond strength than current commercial repair products. Results also shows that commercial repair products gain no bond whatsoever to sawn concrete specimens. Scanning electron micrographs reveal that tungsten mine waste geopolymeric binders chemically bond to the concrete substrate. Cost comparisons between tungsten mine waste geopolymeric binder and current commercial repair products are also made showing that geopolymeric ones are by far the most cost efficient solution. |
