Abstract

PROBLEM TO BE SOLVED: To completely eliminate the elution of salt from seashell and the occurrence of an offensive odor, by mixing an aggregate consisting essentially of ground seashell waste and a cement and water, further adding an inorganic hardening agent and molding. SOLUTION: A seashell waste is ground, mixed with a cement, water and further an inorganic hardening agent to give a fluid. The fluid is placed on a mold and molded into a concrete product, salt components contained in the seashell waste and an organic component to be an offensive odor sauce are effectively fixed by the coexistence of Na<+> , K<+> , Co<+> , Cl<+> , an ammonium salt, etc., contained in the inorganic hardening agent together with the cement. The coexistence can further accelerate coagulation and promote hardening. The elution of Cl and the occurrence of an offensive odor after curing can be reduced even by addition of a large amount of the seashell as an aggregate. Preferably the seashell waste is ground into about 5 mm particle size. Economic effects can be enlarged by increasing the ratio of the seashell waste in the aggregate.
