Use of quarry waste in concrete and cementitious mortars
The compressive strength of concrete with waste quarry dust included as cement replacement was evaluated at 7, 14, 28, 60, 90, and 120 days. In general, lower compressive strengths were obtained compared to their equivalent reference mix, as the waste quarry dust content increased for the constant water-to-binder ratio mixtures.
