La microfissuration superficielle a-t-elle une influence sur la profondeur de carbonatation des bétons?
This work deals with the influence of the superficial microcracking on concrete carbonation. Three types of concrete with strengths ranging between 25 and 60 MPa were subjected to different thermo-hygrometric treatments to create a superficial microcracking, then, to accelerated carbonation tests for 3 months. After their period of preconditioning treatments, the quantification of the superficial microcracking and the measure of the water absorption of the concrete were carried out to observe correlations with carbonation depth. Results show that the influence of the superficial microcracking is strongly dependant of the concrete strength and begins to be significant when concrete strength reaches about 50 MPa.
