Abstract
The aim of the research is to enhance the specifications of adhesives used in the treatment of cracks in the walls of buildings and concrete ceilings in addition to the oxide zirconium nanoparticles. Use epoxy resins and added ZrO2 by weight ratio (0, 1, 3, 5, 7, and 9)%and using the in situ method for Preparation nano composites. To make the mechanical tests (tensile and impact), adhesion test (shear bonding and pull off tests), thermal expansion.The results of the mechanical tests and adhesion test showed that all of the above tests improved the specifications of epoxy resin with the addition of zirconium. The strength of the overlapping material was increased by increasing the percentage of zirconium to 5% and then the strength and stiffness of the material decreased by increasing the ratio (7, 9%) due to the phenomenon of aggregation of nanoparticles.
