WATER-PERMEABLE PAVING MATERIALS USING ENVIRONMENTALLY FRIENDLY INORGANIC BINDERS AND ITS CONSTRUCTING METHOD THEREOF

摘要

PURPOSE: A water permeable paving material, and a construction method of a water permeable paving material are provided to prevent the secondary environmental pollution due to the waste construction material by using an environmentally friendly inorganic binder. CONSTITUTION: A water permeable paving material comprises 15~25 parts by weight of an environmentally friendly inorganic binder; 3~8 parts by weight of mixing water; and 100 parts by weight of aggregate, wherein the aggregate is the washed aggregate of 6~10 mm and the washed aggregate of 1~3 mm. The environmentally friendly inorganic binder comprises 5~20wt% of calcium sulfoaluminate, 0.5~10wt% of waste gypsum, 60~80wt% of ultramicro-granulated blast furnace slag, 0.5~5wt% of ethyl-vinyl acetate-based redispersible powder resin, and 5~20wt% of natural lime.
