Estudio de la influencia que los distintos tipos de refrentado ejercen en el ensayo a compresión de probetas de hormigón

Abstract: Se exponen los resultados del estudio experimental de distintas técnicas de refrentado de probetas de hormigón, todas ellas admitidas generalmente como correctas. Se observan diferencias notables de unos sistemas a otros, recomendándose finalmente el empleo de azufre fundido para hormigones hasta 500 kp/cm^ de resistencia. Se establecen también algunas normas de ejecución que no aparecen en las distintas especificaciones vigentes.

“…Capping with sulphur-filler [10,47,154] was not considered in this research for environmental and health issues as warned in the ASTM C1552-16 [147]. Another reason is that specimens capped with sulphur-filled exhibited similar compressive strength than those capped with cement mortar in previous research on concrete specimens [156,157]. The use of unbonded Neoprene pads [8] was also not considered in this research because its use has been highly questioned [59,105,136,141,142,158].…”
