Abstract

Formulated lime mortars suitable for long-term storage in silos or bags can be produced by adding quicklime to wet, as-received quarried sand. However, sands with high water content may require the addition of more quicklime that would alter the mortar proportioning. This work investigates the possibility to replace part of the lime-dried sand with dry, crushed, mixed glass cullet and calcium carbonate aggregate to allow greater control over mortar formulations. It is shown that the use of glass yields a similar or slightly weaker product, depending on curing regime, than the control while calcium carbonate generates the strongest mortar.
