Abstract

Una losa de hormigón (20) comprende hormigón convencional y un refuerzo combinado de torones de acero postensado (22, 26) y fibras (29). Los torones de acero postensado (22, 26): - tienen un diámetro de 5 mm a 20 mm, - tienen una resistencia a la tracción superior a 1700 MPa. Las fibras (29) están presentes en una dosis que va de 10 kg/m³ a 40 kg/m³, en el caso de fibras de acero están en una dosis que va de 1.5 kg/m³ a 9 kg/m³ en el caso de fibras macro-sintéticas.
