The influence of curing and aging on chloride transport through ternary blended cement concrete

[EN]: The effect of the extension of the curing period and exposure time to a chloride source on the transport of these ions has been studied in concrete with 100% Portland cement (OPC) and with ternary cement composed of 64% OPC, 30% blast furnace slag (BFS) and 6% limestone filler (LF). The extens...

The extension of the curing time (from 28 to 90 days) did not significantly affect the transport, even in concretes with supplementary cementitious materials (SCM’s). The exposure time to the chloride source (3, 6 and 12 months) is a parameter which had a major influence on the transport. At least 6 months of exposure were necessary to achieve stable chloride diffusion coefficients with more noticeable stabilization occurring when SCM’s were used. The presence of BFS significantly decreased the transport, due to its ability to combine chloride rather than the refinement of capillary pores as a consequence of its late hydration.[ES]: Se estudia el efecto de la extensión del tiempo de curado y exposición a una fuente con cloruros en el transporte de dichos iones a través de hormigones con 100% de cemento Portland (OPC) y con cemento ternario compuesto por 64% OPC, 30% escorias de alto horno (BFS) y 6% fíller calizo (LF). La extensión del tiempo de curado (de 28 a 90 días) no afecta significativamente al transporte de cloruros, incluso en hormigones con adiciones minerales. El tiempo de exposición a los cloruros (3, 6 y 12 meses) es un parámetro muy influyente en el transporte, siendo al menos 6 meses necesarios para llegar a coeficientes de difusión estables, con un efecto del tiempo de exposición más crítico en hormigones con adiciones minerales. Las BFS disminuyen significativamente el transporte más por su capacidad de combinar cloruro que por el refinamiento en poros capilares por su hidratación tardía.The authors would like to thank the Ministerio de Economía y Competitividad for financing the IMCORPRO BIA2011-22670 research project and especially Javier Luna for the BES-2012-061300 funds.Peer reviewedCSIC - Instituto de Ciencias de la Construcción Eduardo Torroja (IETCC)Ministerio de Economía y Competitividad (España)Ministerio de Ciencia e Innovación (España)Consejo Superior de Investigaciones Científicas [https://ror.org/02gfc7t72]202020202018info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501Publisher's versioninfo:eu-repo/semantics/publishedVersionhttp://hdl.handle.net/10261/211685reponame:DIGITAL.CSIC.
