Evaluation of abrasion resistance and permeability of pervious pavers with the addition of marble waste

Abstract

In Brazil, the processing of ornamental stones generates large volumes of waste every year, among which marble stands out. Most of this material is still disposed of in landfills, representing a relevant and underutilized environmental liability. As an alternative to mitigate this impact and add technical value to this residue, its application in the production of pervious pavements was investigated. This study builds upon the work of Simões et al. (2023), who evaluated pervious concrete with partial replacement of cement by granite waste, and extends the investigation by analyzing another mechanical property, abrasion resistance, this time using marble waste (RBRO-M). For this purpose, interlocking blocks (pavers) were produced with volumetric replacements of 0, 5, and 10% of Portland cement by RBRO-M. The pavers were tested for permeability, porosity, and abrasion resistance, according to NBR 16416:2015, ASTM C1754 (2012), and NBR 12042:2012, respectively. The results indicated satisfactory values of porosity (greater than 20%) and permeability (above 6,000 mm/h) in all mixtures analyzed. On the other hand, abrasion resistance tended to decrease with increasing porosity, highlighting the challenge of balancing mechanical performance and hydraulic functionality when incorporating this type of residue.
