Abstract:
Through tests of mechanical properties and durability of repaired concrete by carbon fiber cloth,glass fiber cloth and composite waterproof cloth,the effects of these repairing materials on compressive strength,flexural strength ,shear strength,impact resistance,abrasion resistance,frost resistance and permeability resistance of concrete are studied.The results indicate that flexural strength and impact toughness of repaired concrete by carbon fiber cloth and glass fiber cloth is higher than those of the normal concrete;shear strength of repaired concrete by glass fiber cloth and composite waterproof cloth is higher than that of the normal concrete;and abrasion resistance,frost resistance and permeability resistance of repaired concrete by three repairing materials is higher than those of the normal concrete.
