Effect of waste glass addition on mechanical properties of slag based geopolymers

Abstract

Slag is one of the by-products of energy industry which is suitable for secondary industrial processing. Although the slag has been successfully used in industrial production for several decades its use does not achieve the level of its potential. The Slags can be used as alkali activated materials and utilized in synthesis of geopolymers. This work describes an improvement of mechanical properties of alkali activated binders - geopolymers made of blast furnace slag. The effect of addition of waste glass on mechanical properties of geopolymers was examined. The Waste glass was added in a form of broken and crushed glass particles. Samples were tested after 7, 28 and 90 days.
