A repair process developed by a Japanese cement company that utilizes polymer cement mortar and organic paint film is described. The Asana Refresh (AR) process is a concrete body modification process that improves the durability of existing concrete structures by protecting the concrete against further invasion by harmful substances. It can also be applied to new concrete strucures to prevent future degradation. The repairs have high adhesivity, and protection against permeation and diffusion of carbondioxide, oxygen, and water, and against neutralization. It protects against chloride and salt damage, and eases rust removal and rust preventive work. The procedure gives stable performance of inorganic materials and specially formulated styrene-butadiene rubber latex which are mixed under strict quality control. The procedure is econmical compared with resin repair processes.
