Experimental study of the influence of different types of surface treatments on the local repair of columns by jacketing

Description
Summary:Abstract Material deterioration, changes in the use of buildings or incorrect initial structural system may result in the need of structural repair or strengthening. Jacketing of the structural element is a widely used technique for structural repair due to its relatively low cost and relative ease of execution. The present research proposes to experimentally investigate, through the sleeve test, the influence of different surface treatments on the connection between the concrete of an existing structural element and the concrete used in its repair. Comparative study of the observed results allows a better understanding of the influence of surface treatment regarding the restoration of the resistant capacity of columns through the jacketing technique, highlighting the one that presents the best performance.
