cement tile is a kind of roof decoration material. It has the advantages of high density, high strength, light weight, reasonable cement tile type and so on. It has completely changed the traditional cement tile formed by rolling with dry concrete, which is rough, low strength, monotonous tile type and so on. Next, the editor will introduce the specifications of cement tiles and the key points of choosing cement tiles

specification of cement tile

cement tile has the advantages of high compactness, high strength, light weight and reasonable tile type, which completely changes the shortcomings of the traditional cement tile formed by rolling with dry concrete, such as roughness, low strength and monotonous tile type. It has a unique waterproof structure, ultra-high strength, beautiful appearance and so on. Characteristics of cement tile: size: 420mm× long; 330mm wide; Laying: 9 pieces/m2; Single piece weight: 4kg/piece; Applicable gradient: 0o-90o; Specific gravity: 2.2; Water absorption: ≤ 8% ; Bending strength: 2000 Newton, service life of 100 years. The price of cement tiles is generally 1— About 3 yuan a piece, the price difference between different brands is not big

key points for selecting and purchasing cement tiles

1. Appearance

high quality cement tiles have regular appearance, flat and undistorted, and there are no defects and cracks on the front and back sides. When shopping, you can put the tile on a flat place and press it with your hand to know whether it is warped and flat, or take an eye at the side edges on both sides to see whether it is straight

2. Coloring layer

first judge whether the coloring layer is cement or paint. The cement tiles sprayed with paint are bright in color and will not change color or peel off for a long time. When shopping, the former looks at the color layer from the side and the end to have a certain thickness, while the latter is very thin and can see the spray point of the paint

3. Compactness

the compactness index of cement tile determines the strength, water seepage resistance, frost resistance and service life of the tile. The cement tiles with poor density cannot bear large pressure, and there are large and many internal voids, so the impermeability is very poor. In rainy days, rainwater will seep into the back of the tile and drip, and then seep into the roof

4. Impermeability

when purchasing, you can put the tile upside down and add water in the groove for observation. If the water line is straight and neat, it means that the compactness is good and the material is uniform. Otherwise, it means that the impermeability is poor. Then look at the back of the cement tile. If water drops appear on the back of the tile after 24 hours, it indicates that the impermeability of the tile is poor, and the roof will leak in continuous rainy days

scope of application of cement tiles

1. It is mainly used in multi-storey and low-rise buildings, and villas are more suitable

2. It is applicable to roof waterproofing of grade II (one to two waterproof fortifications, with waterproof cushion), grade III (one waterproof fortification, with waterproof cushion), and grade IV (one waterproof fortification, without waterproof cushion). The waterproof cushion is laid under the waterproof layer, which can also be used as a waterproof layer to protect the roof and prolong the service life of the roof. Waterproof coating should not be used as waterproof layer or waterproof cushion

editor's summary: that's all about the specifications of cement tiles and the key points of cement tile purchase. I hope it will be helpful to you. If you want to know more, you can pay attention to information
