    Abstract

    The aim of this dissertation is to investigate the different combination with epoxy, cement and latex (SBR) for repairing a cracked concrete, and carry out a lab test to find the bond strength of repair material with concrete. But, later during the lab experiment it wasn’t possible to find bond strength, so instead, tensile, shear and bending loading capacity of repair material bonded with concrete were found.
    It was determined that the most important properties of repairing materials are modulus of elasticity and bond strength (Wipf, Klaiber, & Raker, 2004, p. 4), also according to the findings from the literature review that all cracks occur due to the tensile stress, so based on these findings, the methodology will be aiming to find the tensile bond strength according to equipment availability, but after many failed attempts to find bond strength, loading capacity was obtained instead.
    Number of repair materials to be used are five different samples, and each sample has different epoxy/cement ratio, where for sample 1,2 and 3 the epoxy/cement ratios are 100%, 90%, 80%. For sample 4 and 5 the epoxy/cement ratio is the same as sample 2 and 3, but with the addition of latex (SBR) in the mixture. From the obtained results it shows that the combination of epoxy, cement and latex, can give better results than epoxy alone and epoxy and cement together. This means, that this dissertation proved that this is a new combination of repair material, it can be introduced into the industry as it shows promising results from sample (S5), as no other research or experiments done on this combination. But, it needs further studies and experiments, as the results obtained are not representative of the repair material properties directly.
