Abstract
In this work, the conditions of self compactability of a self-compacting concrete reinforced with steel fibers have been experimentally evaluated. The concrete has been manufactured by LAFARGEHOLCIM, for its elaboration it has been used CEM II/A-M (P-V) 42.5 R cement manufactured by Lafarge, with a content of 350 Kg/m3 and a water cement ratio of 0.56. Plasticizers (1.9) and super plasticizers (5.8) have been added as additives. As reinforcement, cold drawn steel fibers of 50 mm length and 0.62 mm diameter (slenderness 80.6) have been used, with a dosage of 10 kg/m3, supplied by the company Bekaert with the commercial name Dramix. To guarantee that the studied concrete has the necessary characteristics to be able to catalogue it as self-compacting, we have carried out the tests of runoff, funnel in V, box in L and runoff with ring J according to the instruction EHE-08.
