A pellet for construction material, a building material panel and an artificial fishing reef block using the pellet and manufacturing methods thereof are provided to save the environment by recycling waste glass, to obtain excellent soundproof performance by introducing waste glass for construction and to save the hydrosphere by replacing for cement and concrete. A pellet for construction material is formed by mixing 80-90% by weight of waste glass powder which has particle size of at most 200 mesh, 3-5% by weight of loess powder which has particle size of at most 200 mesh, 3-5% by weight of sodium silicate and 4-10% by weight of water, followed by kneading until sludge state is obtained and forming spherical shape. A manufacturing method of the pellet comprises steps of: dry-mixing 80-90% by weight of waste glass and 3-5% by weight of loess powder in Hobart Mixer; wet-mixing 3-5% by weight of sodium silicate and 4-10% by weight of water with the dry-mixed waste glass powder; stirring the mixed waste glass powder, loess powder, sodium silicate and water until reaching sludge state; subjecting the mixture to injection molding in a mold having a thickness in a length; cutting the injected material in a size of 2-50mm; and forming the cut material in a spherical form. A building material panel comprises: a pellet layer having the globular pellets laminated in a thickness; a lower hard layer which is formed with 60-75% by weight of waste glass powder, 4-6% by weight of loess powder, 6-10% by weight of sodium silicate, 2-3% by weight of lime, 2-3% by weight of calcium carbonate, 3-5% by weight of sodium hydroxide, 3-5% by weight of perlite and 5-8% by weight of water in a thickness beneath the pellet layer; and an upper hard layer which is formed with waste glass powder, loess powder, sodium silicate, lime, calcium carbonate, sodium hydroxide, perlite and water in a thickness on the pellet layer. A manufacturing method of the building material panel comprises steps of: mixing 60-75% by weight of waste glass powder, 4-6% by weight of loess powder, 6-10% by weight of sodium silicate, 2-3% by weight of lime, 2-3% by weight of calcium carbonate, 3-5% by weight of sodium hydroxide, 3-5% by weight of perlite and 5-8% by weight of water; stirring the mixed material; drying the stirred material for the hard layer; laminating the dried material hard layer and the pellet for construction material which is separately prepared in a thickness in a mold; placing the mold in a furnace of high temperature for calcination; and unmolding the material from the mold. An artificial fishing reef block is formed by placing the spherical pellet in a mold after kneading a mixture comprising 80-90% by weight of waste glass powder, 3-5% by weight of loess powder, 3-5% by weight of sodium silicate and 4-10% by weight of water until reaching sludge state, followed by subjecting the mold to calcination. A manufacturing method of the artificial fishing reef block comprises steps of: forming spherical pellets with a mixture comprising 80-90% by weight of waste glass powder, 3-5% by weight of loess powder, 3-5% by weight of sodium silicate, and 4-10% by weight of water; laminating the pellet by placing the pellet in a mold for manufacturing the block; subjecting the mold having laminated pellet to a furnace for calcination; and unmolding a calcinated block from the mold.
