Manufacturing method of building material using stone waste
The present invention relates to a method for manufacturing materials for civil engineering and construction using stone waste, in which stone sludge and stone waste for fine aggregates are used to manufacture materials such as bricks, sidewalk blocks, sidewalk and driveway boundary blocks, retaining wall blocks, slab stones and the like for civil engineering and construction. According to the present invention, the stone sludge and stone waste for fine aggregates are freely separated and sorted out in an efficient way, waste heat discharged and spent in a high-temperature firing kiln is used to enhance productivity and save costs, and at the same time, strength is improved through combination of a given mineral admixture. The method for manufacturing materials for civil engineering and construction using stone waste comprises: a first step (S10) of grinding and sorting out stone waste into stone sludge and stone waste for fine aggregates; a second step (S20) of generating a mineral admixture through combination, which will be mixed with the stone sludge and the stone waste for fine aggregates generated through the first step wherein the mineral admixture includes 30-40 parts by weight of calcium carbonate, 15-20 parts by weight of silicon dioxide, 15-20 parts by weight of kaolin, 10-15 parts by weight of calcium sulfate, 10-15 parts by weight of aluminum oxide, 5-10 parts by weight of magnesium oxide, and 1-2 parts by weight of sodium silicate; a third step (S30) of mixing 70-90 parts by weight of the stone sludge and the stone waste for fine aggregates with 10-30 parts by weight of the mineral admixture and 10 parts by weight of water to generate a mixture of raw materials; and a fourth step (S40) of forming a mixture of raw materials produced through the third step into a molded body having a uniform size to perform firing on the molded body at constant temperature, thereby completing a product.
