- What raw materials are needed to produce artificial stone?

b. 42.5# Portland cement;
c. Washed sand or coarse sand with small stones;
d. Water reducing agent; cold northern climate: antifreeze;
e. Pigment: Shanghai Yipin; Germany Bayer;
f. Release agent.
2.About production procedure:
a. First, prepare the mold and raw materials:
Light weighted gravel; cement; sand/stone powder; water reducing agent; pigment;Prepare these raw materials according to a certain proportion, and then stir them evenly;
b. When mixing the raw materials, can add some yellow and orange pigments in it to eliminate the color of the cement and make the concrete better color;
c. Prepare the spray gun, mix the pigment you want to produce evenly, and pour it into the spray gun;

e. To ensure that the color layer is sprayed evenly, then pour the mixed concrete into the mold, place it on the vibrating table, and vibrate for 10-15 seconds until the air bubbles in the concrete are vibrated out, and the mold should be filled and levelled up during the vibration process.
f. Store the vibrated molds in the drying room in turn, keep the room temperature at 65-70 degrees, and steam for 7-8 hours; if there is no drying room, get a room without windows, install an exhaust fan on the wall, and place the 15-18 hours.
