The properties of innovated mortars utilizing secondary raw material

Abstract

This paper studied lime mortars containing waste brick powder. The powder originates from grinding of thermal insulating bricks. The aim of the study is to find out appropriate application of this secondary raw material. For this purpose we tried to replace silica sand by the brick powder in different quantities (10%, 30% and 50% of weight). An influence of the brick powder replacement is determined through the properties of special mortars, which were compared with a pure lime mortar (with no powder replacement). Specifically in this article experimental methods and results of basic physical properties, pore structure characterization, mechanical properties and hydric transport abilities (water vapour as well as liquid water transport) are described. © 2014 WIT Press.
