Abstract:The cement industry, aware of the environmental benefits of partially replacing clinker with supplementary cementitious materials (SCMs), has been including SCMs in its manufacturing process. This paper analyses the effect of one such material, granite waste, on the hydration and mechanical performance of new blended cements and discusses the results of a multivariate analysis of variance (MANOVA) conducted to ascertain the impact of the factors involved on mechanical strength. The findings showed no differences between the hydration phases present in these and standard cement pastes: the C-S-H gels formed had similar characteristics and mean chain lengths. The pastes bearing 20% granite waste nonetheless exhibited slightly lower mechanical performance, a more refined pore size, and a smaller amount of C-S-H gel than the conventional material. The statistical analysis revealed that the presence of waste and curing age had a significant effect. Interage group differences in mean mechanical performance were found to be more significant at later ages in the additioned than in the unadditioned pastes due primarily to the pozzolanic action of the waste.
