ESTUDO DAS MANIFESTAÇÕES PATOLÓGICAS EM PAREDES DE CONCRETO ARMADO. SINTESE DO MÉTODO CONSTRUTIVO E TRATAMENTO APLICADO A UM CONDOMINIO RESIDENCIAL EM CAMPO GRANDE, MS.

Abstract

This study aims to identify and analyze the most recurrent pathological manifestations in cast-in-place reinforced concrete walls, with an emphasis on cracks, as they are common failures in this type of construction system. Initially, a bibliographic review was conducted, addressing the theoretical aspects of pathologies, their mechanisms of origin, methods of identification, and possible treatment solutions. Subsequently, a case study was carried out in a residential development located in Campo Grande/MS, where visual inspections, crack width measurements using a crack gauge, and crack mapping were performed. The technical analysis, conducted by engineers from the construction company, indicated that the observed cracks were passive in nature, mainly caused by plastic shrinkage of the concrete, intensified by deficiencies in the wall curing process. Based on this diagnosis, the chosen corrective solution was the application of an elastomeric waterproof polymer emulsion, a suitable technique for sealing passive cracks. The results demonstrated the effectiveness of the applied method, contributing to the structure’s durability and the preservation of the building’s functional performance. This study reinforces the importance of a thorough technical approach in identifying and treating pathological manifestations, as well as the adoption of good construction practices to prevent future damage.
