Manufacturing method for soil blocks to be used for environmetal artificial fish selters

摘要

A method for manufacturing environment-friendly soil block for artificial fish reef is provided to show target intensity within one day after installation at a room temperature and improve productivity with reduced costs. A method for manufacturing environment-friendly soil block for artificial fish reef comprises the following steps of: pulverizing 50-70wt% of granulated blast furnace slag, 5-15wt% of CSA-based high intensity blending material, 5-20wt% of calcium hydroxide or quicklime, 10-20wt% of nature II type anhydrous gypsum and 1-5wt% of alum with fineness of 4,000cm^2/g or greater to prepare inorganic binder; mixing 1 part of granite soil or a mixed material of granite soil and yellow soil to the 0.15-0.25 part of inorganic binder and adding 0.1-0.15 part of water to therein by weight to prepare a mixture; inputting the mixture in a mold and compressing the mixture under the condition of pressure of 7-15 tones; and curing the produced mixture as the soil block.
