COMPOSITION FOR ARTIFICIAL STRUCTURE AT THE SEA BEDS, THE ARTIFICIAL STRUCTURE PRODUCED BY THE COMPOSITION, AND METHOD FOR PRODUCING THE ARTIFICIAL STRUCTURE

摘要

A composition for artificial sea-bed structures and a manufacture method for artificial sea-bed structures are provided to realize the manufacture of lightweight and high-intensity artificial reefs, thereby improving workability in the field. A method for manufacturing artificial sea-bed structures comprises the following steps of: preparing a composition for artificial sea-bed structures containing 45-70wt% of perlite, 10-20wt% of dolomite and 20-35wt% of cement; mixing 40-50 parts of water and 25-50 parts of admixture with 100 parts of the composition to obtain a liquid composition; mixing 80-200 parts of fine aggregate with 100 parts of the composition for the artificial sea-bed structures to obtain a aggregate mixture; adding the aggregate mixture to the liquid composition and stirring the mixture; and pouring the mixture into a molding frame.
