Reduction of Concrete Surface Permeability by Using Crystalline Treatment

Popis výsledku v původním jazyce

Maintenance of the present concrete infrastructure is of great concern, because a great many concrete structures are approaching the end of their service lives. Considerable attention in contemporary research is focused on advanced technologies, such as self-healing processes. One the oldest is the use of crystallizing treatments, which improve the impermeability of the concrete and contribute to prolonged durability. This work deals with the reduction of concrete surface permeability properties by using a repair mortar with a crystallizing admixture for penetrating the concrete. The evaluation was based on the chloride migration test, water penetration test and initial surface absorption test (ISAT). The mortar was polished prior to testing to eliminate the barrier effect of the applied mortar and assess the quality of the penetration. The performed experiments confirmed significant improvement of the surface concrete layer based on all the permeability procedures over time. After a year of the program, the permeability of the treated concrete surface was decreased by approximately by 40 %, but the greatest sealing effect was recorded during the first two weeks.
