Effects of the incorporation of residue of masonry on the properties of cementitious mortars

Abstract This research presents the results of an experimental study about the potentiality of using residues of masonry (RM), sampled from construction and demolition waste (CDW), as supplementary cementitious material (SCM). The Portland cement was partially replaced by RM up to 50% in weight (0%,...

The Portland cement was partially replaced by RM up to 50% in weight (0%, 12.5%, 25%, 37.5% and 50%). Various tests were carried out for: pozzolanic activity (fixed lime and strength activity index), the heat of hydration, setting time, the (autogenous and by drying) shrinkage, and compressive strength. Experimental results shown that the RM has a positive activity because the increase of RM replacement level in the mortars generates a lower heat of hydration and autogenous and drying shrinkage. The fixed lime test at 28 and 180 days, indicated that the RM exhibits pozzolanic activity to some degree, and the Strength Activity Index (SAI) according to ASTM C311, was 77.13% and 84.36% at 7 and 28 days, respectively. These results indicate that RM should be considered appropriate for using as supplementary cementitious material.info:eu-repo/semantics/openAccessEscuela de Construcción Civil, Pontificia Universidad Católica de ChileRevista de la construcción v.19 n.3 20202020-12-01text/htmlhttp://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0718-915X2020000300407en10.7764/rdlc.19.3.407
