Abstract:Slurry infiltrated mat concrete (SIMCON) has recently emerged as a high performance steel fiber cementitious composite. Flexural strength, ductility and toughness of SIMCON were found to be superior to conventional steel fiber concrete. Being mechanically rolled at the plant, application of SIMCON in the field is facilitated. With high strength, ductility and ease of construction, SIMCON holds potential for application in repair of deteriorated highway bridge coupled with harsh weather conditions and presence of deicing chemicals result in continuous need for repair and rehabilitation. This paper discusses the potential advantages of SIMCON in repair applications. Mechanical properties of SIMCON including tensile stress-strain behavior and flexural load-deflection relation are reviewed. Investigation of the interfacial bond strength of SIMCON overlay and concrete substrate is focused in this project. To assess bond between plain concrete substrate and SIMCON, the effect of shear nails and latex was studied. Furthermore, air permeability of SIMCON via nondestructive testing was studied. Test results indicate the potential of SIMCON for use in repair and rehabilitation of pavements and bridges.
