PURPOSE: Provided is a production method of artificial rock with strength and material like natural rock by forming rock-shaped silicon rubber mold and filling GRC mortar on the mold with a cement paste. The artificial rock is used for preventing destruction of nature and restoring damaged nature. CONSTITUTION: The artificial rock is produced by the following steps: preparing a GRC mortar by mixing 80kg of cement, 56kg of sand, 24-30kg of water, 2.4kg of glass fiber, 0.8kg of water-reducing agent, 2.4kg of polymer, 0.8kg of an agent for controlling whitening, and 2.4kg of pigment; preparing a cement paste by mixing 15kg of cement, 3kg of fine sand, 4.5-5.5kg of water, and 0.45 kg of pigment; reproducing rock by coating the rock with wax, and using silicon rubber; covering silicon rubber with fiber reinforced plastic(FRP); plastering the cement paste on the silicon rubber mold; filling the GRC mortar on the paste with removing foams; curing and de-molding the GRC mortar from the silicon rubber mold modifying holes on the GRC mortar with cement paste; spreading water on the GRC mortar to increase strength, and curing. The above pigment comprises Fe2O3, H2SiO4, Al2O3, CaCO3, and C for coloring dark brown, and Fe2O3, H2SiO4, Al2O3, and CaCO3 for coloring pale red.
