Manuf. Red Bricks & Roof Tiles

Man's Use of Earthen Bricks and Tiles

Red Bricks and Tiles are the materials resulted from mud, which man had known since a long time and used in building his home and making pottery plates. The archeological excavations discovered some potteries dated to thousands years ago, however, they still preserve their quality and are not affected by the environmental factors. Additionally, pottery material resists salts existed in soil and salty water. It is considered also one of the favorite materials used in construction in salty soils and beaches areas, because it resists humidity, especially in mountainous areas. This is why tiles and red bricks are widely spread in Europe and other countries which have high cold and humidity. They are used also in the hot areas due to the fact that they insulate temperature and have little thermal conductivity.

Since tiles and red bricks resist salts and humidity, the buildings of the Italian city Venice are constructed of tiles and red bricks, and they are not affected by environmental factors, even Venice locates in the sea. Today, there are many existed landmarks built of tiles and red bricks around the world. The main features of tiles and red bricks, which are the solidity, light weight, humidity resistance, thermal and sound’s insulation, ease of construction, and quality maintenance for years, have put them in the first place in construction, and promoted their manufacturing development with the existed technologies.

1. Extraction and Manipulation of Raw Materials Process
A

The mud used in the tiles and red bricks industry is extracted from Al – A’aqool Valley in Al Madeena El Monawara next to the factory. The mud is collected in large yard; fine sand is added and mixed till being homogenous.

B

The mixture then pushed to large basins, a certain percent of water added and then the mixture is left for 3 – 10 days. This process is called fermentation.

C

After fermentation period, the raw materials are fed in the feeding box and moved to the breaker, where they are broken down and grinded to less than 1 millimeter in size. Then they moved to the moistening and softening grinder. After that, the mixture is moved to the final grinder where we have the final fine powder.

2. Tiles and Bricks Shaping Process

The mixture pushed to the shaping compressor according to the required molds and the tiles and bricks column will be divided according to these molds. Then, the tiles and bricks are kept in divided carts to be moved to the dryers.

3. Drying Process

The carts of tiles and bricks are moved inside the dryers, where they are exposed gradually to hot air for three days, after which the tiles and bricks are being completely dry.

4. Burning Process

After the drying process, the tiles and bricks are loaded to the oven’s carts and burned gradually and directly by diesel, under temperature arrives at 900 C. Consequently, tiles and bricks will have red color resulted from the chemical interactions of the mud.

5. Wrapping Process

After burning, tiles and bricks are moved to cooling warehouses, then to automated wrapping and storing. Finally, they will be loaded and transported to sites and enterprises’ locations.
