Use of waste glass in cement mortar

The need to add value to wastes and the opening towards the use of sand replacement materials, both in mortars and concretes, with the purpose of promoting increased sustainability of building materials, were the grounds for this work that aims the formulation of mortars with crushed glass aggregate. In this paper, a parametric experimental study for producing mortar blocks using fine and coarse waste glass is presented. Mechanical properties of mortar blocks having various levels of fine glass (FG) and coarse glass (CG) replacements with fine aggregate (FA) are investigated. The test results show that the replacement of Fine aggregate by Fine Glass at level of 20% by weight has a significant effect on the compressive strength of the mortar blocks as compared with the control sample because of pozzolanic nature of FG. Results indicate pozzolanic reactivity of this waste and open possibilities for the use of this material in mortars
