Bond Behavior Of Carbon Laminate Strips Into Concrete By Pullout-bending
Tests
Bond in Concrete пїЅ from research to standards, page 8. Budapest, (2002)Abstract
During the last years it has been investigated a reinforcing technique
based on introducing carbon laminate (CFRP) strips into saw cuts
made on the concrete cover of the element to be strengthened. The
CFRP is fixed to concrete element using epoxy adhesive. Comparatively
to the techniques that glue the CFRP to the external surfaces of
the concrete element, the one proposed in the present work has the
advantages of mobilize high percentage of the tensile strength of
this composite, prevent the peeling phenomenon and add an extra protection
against fire and vandalism acts. To characterize the bond behavior
of the CFRP strips to concrete, pullout-bending tests were carried
out. The influence of the concrete strength and the embedment length
was analyzed in the experimental campaign. In the present work the
tests performed are described and the results obtained are presented
and discussed.
