POROUS LIGHT WEIGHT MATERIAL AND METHOD OF MANUFACTURING THE SAME
The artificial pumice stone which has strength with them, and the sintering foam which utilized the mixture of the waste glass.
The invention can be applicable to a soil amendment material, water quality purification materials, the artificial culture medium for revegetation, a dehumidifying material, etc.
Construction material
PROBLEM TO BE SOLVED: To provide an artificial soil material or artificial pumice stone by manufacturing a porous lightweight sintered foamed body using waste glass, clay and waste material-utilized woody charcoal as raw materials.SOLUTION: A method of manufacturing the porous lightweight material is carried out by kneading the waste glass powder, clay powder, the woody charcoal powder and a foaming agent with water, granulating the kneaded product and then firing the granule. A layered nearly spherical body is formed because the energy transfer of each material occurs by heat of firing in foaming step occurs and then the clay useful for the growth of plant gathers to the outside, the glass gathers in the middle and the woody charcoal gathers in the center to form layer distribution.
