The Research Of Adhesive About Carbon Fiber Reinforced Concrete Construction

With many experiment of dilution, increasing toughness and adding additive ,we change some surbordinate property of epoxy resin reaction system which can be used to conglutinate carbon fiber and damaged concrete . In low temperature and humidity of actual circumstance, we do some research about using dissimilar resin.Firstly we choose reaction system of the epoxy resin and polyamide according to its well quality in normal temperature. Then we do a series of experiment to ameliorate dilution, toughness and solidify speed .we have three parts of whole felt system, these three parts have dissimilitude quality in order to felt carbon fiber and concrete tightly, which can work in line. We also do some practical experiment to have conclusion that this adhesive system can be used to carbon fiber reinforced concrete constructure technology.Secondly we do some research about using dissimilar resin and solidifition considerating low temperature and humidity of actual circumstance .we find basic composition.Finally, According to GB, we make a series of experiments on its performance, mainly conclude tensile strength, compressive strength, coherent strength with concreat, during and etc. Simultaneously, microscopic pictures, SEM (scanning electronic microscope) analysis were used to investigate the different break shape.
