Abstract

PURPOSE: To easily remove stuck ready mixed concrete by bringing the stuck ready mixed concrete into contact with hydrogen peroxide or a compound, releasing hydrogen peroxide. CONSTITUTION: A washing liquid incorporating 0.1-35 wt.% hydrogen peroxide is brought into contact with the ready mixed concrete stuck to a wall surface. Then a mixer or a pump is rotated to bring them into uniform contact with each other. Thus, a water-soluble high polymer compound is oxidized and decomposed, and the ready mixed concrete can be easily and perfectly washed and removed in a short time and at a low cost.
