Abstract:

A potential application for the use of cullet glass is as a supplementary cementitious material (SCM). Cullet is a ground soda-lime-silica glass waste that has the potential to react with calcium hydroxide (CH) produced as a secondary product from the hydration of Portland cement (PC) in forming principal calciumsilicate- hydrate (C-S-H) strengthening phases. Additionally, the relatively high sodium content of the glass has the potential to act as precursor for the activation of aluminosilicates such as fly ash (FA). This paper investigates this potential by using these wastes in autoclaved hydrated lime CH-silica systems. Compressive strengths of autoclaved compacted cylinders were evaluated and the results demonstrate that the addition of ground glass provides higher strength, when used as a partial silica substitute, and aids in the activation of FA. © 2013 Taylor & Francis Group.
