CERAMIC COMPOSITION USEFUL AS ARTIFICIAL REEF TO IMPROVE GATHERING OF OCEANIC LIVES IN FLOCKS, DURABILITY AND ADSORBING PROPERTIES OF POLLUTANTS

摘要

PURPOSE: A ceramic composition useful as an artificial reef is provided to improve gathering of oceanic lives in flocks due to porous surface, durability due to high strength and density and adsorbing properties of water pollutants, thereby improving the water quality. CONSTITUTION: The ceramic composition useful as an artificial reef comprises 5-30wt% of loess, 5-20wt% of calcined loess, 5-30wt% of clay, 40-60wt% of schamotte, 1-10wt% of agalmatolite and pottery stone and 1-10wt% of shell powder. The ceramic composition is produced by: mixing 5-30wt% of loess, 5-20wt% of calcined loess, 5-30wt% of clay, 40-60wt% of schamotte, 1-10wt% of agalmatolite and pottery stone and 1-10wt% of shell powder with water while stirring; dry-molding the resultant having the water content of 2-6%; drying the molded product for 2-3 days at ambient temperature with air, and then at 40-140deg.C; and calcining the resultant at 1200-1300deg.C.
