<p><P>PROBLEM TO BE SOLVED: To provide a concrete processing composition which can be applied right after the injection of concrete, can form a film on the surface of the concrete, can reduce the delay of a construction in this manner, and increases the strength of the concrete slab. <P>SOLUTION: On the exposed surface before hardening of a concrete layer which is formed by injecting concrete, (a) a water polymer binder of 5 wt.% to 70 wt.%, and (b) the processing composition containing a liquid selected from a group comprising water and solvents are applied. In this case, the water polymer binder contains at least one kind of an ethylene type unsaturated phosphate monomer or an ethylene type unsaturated phosphonate monomer of 0.2 to 10 wt.%. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
