Abrasion resistance and color retention assessment of porous concrete modified by PVA emulsion/PP fiber

The effects of PVA emulsion / PP fiber on the properties of porous concrete is investigated. The experimental results show that the PVA emulsion can significantly improve the compression strength of porous concrete whereas the effect of PP fiber is not obvious. When the content of emulsion or fiber is 1 wt. %, the abrasion loss of porous concrete decreased by 44.1 % or 54.1 %, respectively. Simultaneously, the corresponding chromatic aberration is 44.8 % or 53.3 % lower than unadulterated sample, respectively.
