Improving the interface bond between fiber mesh and cementitious matrix

Mu, B. / Meyer, C. / Shimanovich, S.

The use of continuous fiber mesh as reinforcement of cementitious composites is attractive for various applications. In this paper, fracture toughness was used to evaluate the flexural behavior of glass concrete reinforced with either AR-glass or polypropylene fiber mesh. AR-glass fiber mesh was found to be much more efficient, but polypropylene fiber mesh is less expensive and has no aging problem. A research project is underway at Columbia University to improve the bond between the polypropylene fiber mesh and cementitious matrix. Results obtained so far indicate a great improvement of the mechanical properties of the fiber mesh-reinforced material.
