Use of quarry waste in concrete and cementitious mortars
The use of waste quarry dust to partially replace river sand was investigated (Gopalakrishnan et al., 2020) by studying the effects on the properties of lightweight foam concrete at five contents, starting at a 10% replacement and up to 50% replacement at 10% increments, in mixtures with only cement included as binder.
