Résumé:
This thesis aims at evaluating the efficiency of clogging of cracks in the paviment of Portland
cement concrete, the work of BR-101-Northeast, Lot 05, recovered by application of the
injection spray colloidal microcement It uses resources with methodological literature,
technical visits and preparation of case study, present a brief history about the types of
paviments of Portland cement concrete and its properties, deterioration and rehabilitation of
these types of paviments and the description of the pathology detected. In the evaluation of
paviment were used axial compression tests and optical microscopy, observing and cracking
resistance parameters. Presents and analyzes the results obtained by application the injection
of spray colloidal microcement syrup into cracks of the pavement of the work mentioned. It
was concluded that recovery of pavement Portland cement concrete application of the
technology of injection spray microcement treatment of the pathology identified in this
particular work, was less efficient with regard to clogging and may thus influence on changes
in physical and mechanical characteristics especially with regard to durability. It is suggested
then that monitoring is done on that floor through the fatigue test, or others as a means of
preventing and until same investigation on his life.
