METHOD OF PRODUCING MOSS-INHABITING RETAINING WALL SLAB FOR EARTH

摘要

PURPOSE: To inhabit moss, by placing concrete after charging a cement mixture including vegetable chips, among natural stones on sand spread on a form and removing the form after curing and scraping the surface of the mixture. ;CONSTITUTION: A dry non-cured material 1 like natural sand is spread in a basic form A with the bottom plate. Natural stones 2 are arranged to make a plane. A mixture 3 composed of vegetable chips, coarse sand, and cement is charged in the void of the stones 2. And reinforcements are arranged thereon and concrete 4 is placed. After curing, the form is removed. The surface of the mixture 3 among the stones 2 is lightly scraped by a metallic brush to form a ragged surface. In this way, moss can inhabit naturally on the surface of mixture. And the alkaline concrete surface can be neutralized owing to the sap of the vegetable chips. And this slab can be easily and inexpensively produced and the strength and the durability can be secured.;COPYRIGHT: (C)1995,JPO
