Effect of mineral aggregates and chemical admixtures as internal curing agents on the mechanical properties and durability of highperformance concrete por Vázquez Rodríguez, Francisco Javier, Elizondo Villarreal, Nora, Hypatia Verástegui, Luz, Arato Tovar, Ana María, López Perales, Jesús Fernando, Contreras de León, José Eulalio, Gómez Rodríguez, Cristian, Fernández González, Daniel, Verdeja, Luis Felipe, García Quiñonez, Linda Viviana, Rodríguez Castellanos, Edén Amaral

“…The effectiveness of internal curing to develop higher strength is attributed to control in the porosity and a high water release at a later age. Finally, the lowest permeability value at 90 days (945 C) was found by the substitutions of fine aggregate by 20% of pumice stone saturated with shrinkage reducing admixture into pores and OPC40C by 15% of pulverized fly ash. …”
