Abstract:
The patching techniques developed for architectural concrete on the Saudi National Guard Head-quarters Complex Project in Saudi Arabia are de-scribed. Experimental investigations were conducted to determine the best mix coloring, texturing procedure, and placement method for a variety of con-crete defects. The three principal finishes requiring patching were the light abrasive blasted, heavy abrasive blasted, and hammered ribbed form surface. It is concluded that with exacting care and time a patching procedure can be developed which renders the color and texture of the patch very near that of the parent concrete. [Authors]
