Title:
WATER RETAINING MATERIAL COMPOSITION FOR PAVING AND METHOD FOR APPLYING WATER RETAINING PAVING
Document Type and Number:
WIPO Patent Application WO/2007/023570
Kind Code:
A1
Abstract:
This invention provides a water retaining material composition for paving,
which can be produced without the need to use any special production apparatus
and does not substantially cause a deterioration in properties even after the
elapse of one year or longer after use in the application of paving, and a method
for applying water retaining paving that uses the water retaining material composition
for paving, can efficiently absorb rain water even in the case of short-time severe
rainfall, and has a road surface cooling capability high enough to prevent a heat
island phenomenon. The water retaining material composition for paving is characterized
by comprising 100 parts by mass of a mixture and 1 to 35 parts by mass of cement, the
mixture comprising 70 to 99.95% by mass of an inorganic powder having such a particle
size distribution that not less than 60% by mass of the powder is accounted for
by particles having a diameter of not more than 425 μm, and containing not
less than 50% by mass of any one of SiO2 and CaCO3 or not less
than 50% by mass in total of SiO2 and CaCO3, and 0.05 to 30%
by mass of a granulated blastfurnace slag. The inorganic powder may be a silt-based
powder.
