We have a complete 3D video as a reference for the entire process of paver tiles production, covering almost all links.
(1) Select raw materials, 42.5 Portland cement, coarse river sand (preferably washed sand), stones with a particle size of 5-10mm are preferred.
(2) The proportions of the above concrete and color layers are all based on the standard above C30, Cement: sand: gravel: water=1:1.49:2.59:0.49;
(3) Mix the first layer of color layer and the second layer of concrete layer according to the ratio of the above guidance, keep stirring for 10-15 minutes, do not stop stirring, the stirred material should be kept neither thin nor thick.
(4) It is best to choose the best quality brand of pigments, such as Yipin, because the content of iron oxide is high and the coloring is good, the paver tiles made are not
fades easily and is produced with less than normal quality quantities; also available with our own high percentage pigments.
The total amount of water reducer and brightener can be kept at 0.3%, and it should be noted that the colored concrete (first layer) must not put too much water, because the more water there is, the stronger the alkali return will be, and the color of the floor tiles will be greatly affected in the end.
(5) Stir the prepared materials according to the ratio for more than 10 minutes, and pour the first color layer into the plastic mold, keep the uniform thickness of the material above 10mm, vibrate in time for 10-15 seconds until the air bubbles in the concrete are vibrated, and then place the second layer of concrete is poured into the plastic mold and vibrated and smoothed again for 5-10S.
(6) Transport the plastic mold filled with concrete material to the drying room and keep the indoor temperature at 50 degrees) (Need to be installed in the drying room
One heater) for 10-15 hours to release;
If there is no drying room, it can be dried under the stone shed (2-5 days).
7.After demolding, the paver tiles should be stored in the warehouse for more than 7 days, can be sprayed with water, and can be packaged and sold when the time is up.
