Abstract:Three high molecular weight methacrylate monomer systems were tested to determine their effectiveness in repairing cracked portland cement concrete (PPC). Ultimate strains across repaired cracks, modulus of rupture, and percent of crack filled for slabs repaired with the monomers and stiffnesses of repaired beams were investigated. Tests on small, cracked slabs were also conducted under hot and wet conditions. One hundred thirty-five PCC slabs, 9 PCC beams, and 12 tension specimens were tested. The results varied with respect to the stiffnesses of the polymers. All monomer systems were shown to increase the stiffness of cracked flexural members and to fill cracks as small as 0.1 mm in width. The performance of the systems was affected adversely by moisture and heat. Minimum drying periods after saturation of the cracked concrete with water were determined.
