<P>PROBLEM TO BE SOLVED: To provide a composition mixture which is easy to execute at a site and excellent in water holding property and water permeability after solidifying, has moderate strength, prevents propagation of pathogenic bacteria for plants, is relatively easy to crush after use and has characteristics allowing to easily put back to soil. <P>SOLUTION: This granular composition for a floor comprises the granular mixture obtained by mixing 5-15 pts.wt. of silt of mountain sand, 1-5 pts wt. of peat moss, 15-30 pts.wt. of portland cement as inorganic solidifier and 0.1-0.5 pt.wt. of a nonionic surface active agent with 100 pts.wt. of Kanuma soil with a diameter of 0.5±0.1 mmψ. It is possible to form a solidified layer having both water holding property and water permeability by laying the granular mixture on a floor and directly sprinkling water onto the surface. <P>COPYRIGHT: (C)2007,JPO&INPIT |
