<p>PURPOSE: A simple manufacturing method of artificial stones which give the same feeling as natural stones, replace high cost raw materials like cement, and save manufacturing cost. CONSTITUTION: The manufacturing method of artificial stones comprises the steps of: mixing 70-85wt.% of waste stone powder(0.5-4mm) as a filler, 6-10wt.% of cement and 0.6-1.0wt.% of sand; adding 0.08-1.12wt.% of mineral flocculant such as zeolite or bentonite, 0.8-1.2wt.% of water and 0.3-0.5wt.% of lignin sulfonate; adding 0.3-0.5wt.% of hardening accelerator such as triethanol amine, calcium chloride or natrium; adding 0.8-1.2wt.% of pigments based on oxides; pouring prepared slurry into a mold and discharging air; hardening it by curing at 25-35deg.C for 4hrs; de-molding; and packing. The amount of each component used in mixing is based on the slurry of artificial stone.</p> |
