Cement tile is a kind of roof decoration material. It has the advantages of high density, high strength, light weight, and reasonable type of cement tile. It completely changed the traditional cemented tile with dry-hard concrete through roller compaction and has rough and low strength. Monotonous and so on. Next, Xiaobian will introduce cement tile specifications and cement tile selection points.
Cement tile specifications
Cement tiles have the advantages of high compactness, high strength, light weight, and reasonable tile type, which completely change the traditional shortcomings of dry cemented concrete, such as rough cement tile, low strength and monotonous tile type. It has a unique waterproof structure, high strength, beautiful appearance and so on. Cement tile features: Size: 420mm long x 330mm wide; laying: 9 pieces/m2; single piece weight: 4Kg/piece; applicable slope: 0o-90o; specific gravity: 2.2; water absorption: 8%; flexural strength: 2000 Newtons, with a service life of 100 years. The price of cement tiles is generally about 1-3 yuan, and the price difference between brands is not big.
Cement tile purchase points
1, appearance
The high-quality cement tiles are regular, flat and untwisted, with no cracks on the front and back. When you buy, you can place the tile in a flat place, press the hand to see if it is warped, or use your eyes to look at the side edges to see if it is straight.
2, color layer
First determine whether the coloring layer is cement or paint. Cement tiles painted with paint are colorful and do not discolor or peel off. When purchasing the former, the former looks from the side and ends to a certain thickness of the color layer, the latter is very thin, and can see the paint spray point.
3, density
The compactness index of the cement tile determines the tile strength, water permeability, frost resistance and service life. Cement tiles with poor density cannot withstand large pressures, and the internal voids are large and numerous, so the impermeability is poor. In the rainy days, rain will seep into the back of the tile, and then seep into the roof.
4, impermeability
When you buy, you can put the tile back and put water in the groove to observe. If the water line is straight and tidy, it shows that the density is good and the material is uniform. Otherwise, the anti-leakage is poor. Look at the back of the cement tile. If there is a bead on the back of the tile after 24 hours, it means that the tile has poor impermeability, and the roof will leak during continuous rainy days.
Application of cement tile
1, mainly used for multi-storey and low-rise buildings, more suitable for villas.
2. Suitable for waterproof grade II (one to two waterproof and waterproof cushion), Class III (waterproof and waterproof, and waterproof cushion), IV (waterproof, no waterproof cushion) Waterproof roof. The waterproof cushion is laid under the waterproof layer and can also be used as a waterproof layer to protect the roof and prolong the service life of the roof. Waterproof coatings should not be used as a waterproof or waterproof mat.
