Cement color brick is the collective name of all road bricks, environmental brick is one of them is the use of fly ash .Cinder.Coal gangue.Tailings.Chemical slag or natural sand.It is a new type of wall material made by using fly ash, coal slag, coal gangue, tailing slag, chemical slag or natural sand.Hotel.Clubs.Sidewalk.Small district road.Parking lot.Pedestrian street.Open-air recreation ground, etc.

Cement color brick making method

1. Mixing time: long mixing time can be mixed evenly.Dry mixing material 20 minutes than 10 minutes of strength increased by 15-23%; wet mixing material time to material does not clump as appropriate.Mixed material storage time to about 2 hours is appropriate, too long or too short, will reduce the compressive strength of the brick. 2. molding pressure: clay cement color brick molding pressure, to 500 kg per square centimeter is best.Under this pressure, its products have high compressive strength and good water resistance.If the pressure is too low, it is not easy to be compacted.3. Maintenance conditions: Clay cement color bricks are generally protected by using solar energy.Sunlight natural maintenance 7 days age strength, equivalent to 28 days age strength of 67-90%; 28 days age strength for a quarter age strength of 80-95%.Therefore, if the maintenance site is small, the clay cement color brick can be shipped after 7 days of natural maintenance.

Cement color brick formula

1. clay: it must contain a certain amount of loose particles to facilitate the mixing of cement.Clay with less sand content can be mixed with sand in the soil.Clay with less sand and harder clay must be ground and then mixed with sand.2. Cement: Mixing 10% of 425# ordinary silicate cement can improve the strength and water resistance of the brick, and it will not crack after being immersed in water.Otherwise, the general brick body will appear cracking phenomenon. 3. admixture: mixed with a small amount of admixture (strengthener), in addition to improve the strength of the brick, but also can effectively reduce the amount of cement, reduce the cost of products. 4. water: water consumption is appropriate, the strength of the brick is high.Forming moisture less, the strength of the brick is poor, the resistance of the material in the mold is large, single-sided pressure, brick bottom surface is not dense; forming moisture more, the bottom surface is wet, easy to touch when out of the mold.When the moisture content of sand and soil is 3-5%, the amount of water used in molding is 10%.If the raw material is too much fine sand, it is reduced to 8%.

Cement color brick price

The factory price of cement color brick is about twenty to thirty yuan per square meter, which will not be very expensive, and the market price is about fifty yuan at most.
