Acesso em: 10 mar. 2020.0950-0618http://www.repositorio.ufop.br/handle/123456789/12410This paper presents a study that includes increase in clinker replacement and waste consumption in cement-based composites. Techniques for performance optimization of waste-based supplementary cementing materials in densely packed matrices using basic oxygen furnace slag, iron ore tailings from a tailings dam, quartz mining tailings and quartzite mining tailings were evaluated. Powders with different particle size ranges were produced and characterized. A highly-packed sand-concrete reference mix was designed and six different mixtures with 10−60 vol% partial cement replacement were evaluated. The high binder efficiencies observed and physical-mechanical performances evidence the effectiveness of the proposal, expanding the concept of low-cost supplementary cementing materials and broadening the range of residual materials suitable for use in cement-based composites.en-USrestritoParticle packingIndustrial waste recyclingArtigo publicado em periodicohttps://www.sciencedirect.com/science/article/abs/pii/S0950061819303496?via%3Dihubhttps://doi.org/10.1016/j.conbuildmat.2019.02.054
