| Abstract Scope |
The use of latex modified concrete deck overlay systems has become a common practice for repairing old bridge overlays and as a wearing and protective surface for new bridges. However, cracks due to diverse reasons have been observed in bridge decks, so that reduction or even elimination of cracks is a subject of continuous research. This paper presents the results of the development of latex modified concrete reinforced with short length randomly oriented carbon fibers. Two fiber lengths were introduced to typical latex modified concrete mix in order to evaluate different mechanical properties used as indicators of the performance improvement. Results show that the resulting material tends to be less stiff than plain latex modified concrete, so that for the same load level, carbon fiber latex modified concrete is able to support more tensile strain without cracking. |
