Polymer-Based Repair Mortar Containing Waste Perlite Powder

Abstract

This paper deals with the problematics of utilization of waste perlite from production of expanded perlite in polymer-based material. The goal of this paper is to develop repair mortar containing as high amount of waste perlite as possible as substitution for filler. The resulting mortar exhibits very high physical-mechanical properties such as high bonding strength to a large variety of building materials. The microstructure and the re-dispersibility of filler were also studied.
