Abstract:
This paper presents an evaluation of the use of a new innovative cementitious material, commercially known as Grancrete PCW, as an alternative to epoxy for FRP strengthening systems used for reinforced concrete (RC) structures. Grancrete is an environmentally friendly material that develops high early bond strength and possesses an excellent resistance to fire. The study includes an experimental program to evaluate the behavior of seventeen RC slabs strengthened by using different types of fibers. The load carrying capacity, ductility, and mode of failure of the strengthened specimens were evaluated and the results were compared to control specimens. Results of the experimental program showed that Grancrete PCW paste could be used as an alternative bonding material.
