A water retention test was conducted on No. 12). In this water retention test, first, 1 liter of each green sprayed vegetation material was packed in a 1 liter cylinder in a loosened state, and the weight W1 of each green sprayed vegetation material was measured. Next, after each of the above-mentioned greening sprayed vegetation materials is immersed in water for 24 hours to absorb water sufficiently, each greened sprayed vegetation material is taken out of the water and hung so that water falls by gravity into the room for 24 hours. After the lapse of time, the weight W2 was measured. And 48 in a dryer at 80 ℃
After allowing to dry for a period of time, the absolute dry weight W3 was measured.

It can be understood that the No. 8 greening sprayed vegetation material has both a larger water absorption amount and a greater water retention capacity than the No. 9 to No. 11 greening sprayed vegetation materials and is extremely excellent in water retention. In addition, the greening sprayed vegetation material (No 1
Compared to 2), in No9 to No11 greening sprayed vegetation material, the water absorption amount and water retention amount are small in any case of the mixing ratio of pearlite, whereas in No6 to No8 greening sprayed vegetation material, the above No. 12 was used. The water absorption amount and the water retention amount are both larger than those of the above-mentioned greening sprayed vegetation material, and it can be understood that the water retention property is remarkably enhanced by mixing the perlite.
