<p>PURPOSE: A water-permeable concrete composition is provided to form a chemically and physically stable water-permeable concrete structure by replacing cement with a binding material mixed with a polymer and a filler. CONSTITUTION: A water-permeable concrete composition with the flexibility contains the following: aggregate which contains less than 30% of aggregate particle smaller than 5 millimeters with the soild volume rate of 60~70%, or fine aggregate with the size of 2.5~5 millimeters; 3~15% of polymer for the total weight of the aggregate; 3~30% of filler selected from the group consisting of blast furnace slag powder, fly ash, heavy calcium carbonate, or their compound for the total weight of the aggregate; and 1~5wt% of pigment for the polymer and the filler.</p> |
