Abstract
The fiber reinforced inorganic polymer (FRiP) strengthening system exhibits much improved fire resistance and compatibility with the concrete substrate compared to the fiber reinforced polymer (FRP) strengthening system. Since an inorganic paste is used to replace organic resins as the matrices and the bonding adhesives in the FRiP strengthening system, its success depends greatly on the properties of inorganic pastes. This paper presents a comparative study on the performance of different inorganic pastes, which are based on magnesium phosphate cement (MPC), magnesium oxychloride cement (MOC), geopolymer (GP) cement and polymer modified cement mortar (PMM). The flow, pot life, compressive strength, flexural strength and bonding strength with cement mortar of the aforementioned binders and the tensile strength of the formed FRiP composites were carefully examined. It is shown that MPC and MOC binders are most promising candidates to be the matrix and the adhesive for the development of FRiP strengthening systems. © 2013 Sustainable Construction Materials and Technologies.
