Meet Hebel Size, the material chosen for your construction needs
Hebel is a modern building material that is increasingly used today. Since its introduction in the 1920s, hebel has become the material of choice for building and housing construction, including in Indonesia. Hebel has various advantages that ordinary conventional bricks do not have.
For those of you who need building materials and plan to use Hebel, here is an explanation of the advantages, disadvantages and sizes of Hebel.
Hebel at first glance
In some parts of Indonesia, light brick is known as hebel. The name is a trademark of the party that first introduced lightweight bricks in Indonesia, PT Hebel Indonesia (1995-2015).
The very name Hebel is the surname of the German construction engineer Josef Hebel, who in 1945 had the idea to give reinforcement or bone to a light brick mortar, producing more diverse end products such as floor slabs, walls and so on. These products helped build Germany so that it quickly recovered from the devastation caused by World War II.
Meanwhile, the light brick itself was made by a Swedish architect, Dr. Johan Axel Erikson. However, the findings are the result of chance findings. Since you want to dry quickly, Dr. Eriksson autoclaves his lightweight brick mortar (autoclave, a high-pressure steam heat sterilizer) in his laboratory. The result is the lightweight brick we see today.
Light or hebel dough consists of quartzite sand, water, lime, cement and gypsum. What distinguishes it from ordinary cement or concrete mixtures is the addition of a developer that makes the concrete air-porous (ventilated) like a sponge, so it is light in weight. The added developing material is aluminum powder. All ingredients are then cooked (cured) in the autoclave. Therefore, Hebel is also called AAC lightweight brick (Autoclaved aerated concretei.e. air-porous concrete that has been sterilized in an autoclave).
In addition to the lightweight AAC type brick, there is also the lightweight CLC brick (Cellular lightweight concrete). The two main things that differentiate AAC lightweight bricks from CLC are the construction materials and the drying process. CLC lightweight bricks use a protein-based or synthetic developer. The drying process also takes place naturally. In terms of weight, CLC lightweight bricks are heavier than AAC. In addition, the color of CLC is gray, while AAC is white.
Advantages of hebel
Due to its porous structure, hebel is much lighter than classic concrete. Its weight is about 5 times lighter than ordinary concrete. Although it is light, its strength is still on par with concrete. In addition, hebel is a building material that is soundproof and resistant to earthquakes, water and fire.
Since it is easy to cut and has a standard and precise size, the installation of the hebel can also be done quickly and neatly. The flat surface makes the hebel suitable for an open look or exposed. However, if you want to re-smooth it with acyan, you don’t need a thick layer of coating, just about 2 millimeters. In terms of plastering material, compared to conventional bricks, you only need half the plastering material.
Lack of hebel
With all its advantages, Hebel also has disadvantages. First, the price of hebel is more expensive than the price of conventional bricks for the price per square meter. Second, hebel installation requires a special cement in the form of instant cement. Even during installation, the hebel should not be exposed to water so that it dries easily. Therefore, its installation requires a professional craftsman.
In addition, since hebel-sized pieces are quite large, the risk of leaving a piece is also high if it is placed against a medium-sized wall.
Hebel size type
There are 2 types of hebel sizes or light bricks, namely standard and jumbo sizes. The standard size of the hebel has a length and width of 60×20 cm. Hebel jumbo size has a length and width of 60 × 40 cm. Meanwhile, the thickness options are the same, namely 7.5cm, 10cm, 12.5cm or 20cm. Hebel sizes 7.5 cm and 10 cm thick are the most commonly used types.
Usually hebel is sold based on hebel size per square meter or per cubic meter. The number of hebel sizes per cube for standard hebel sizes of 7.5 cm thickness is 111 pieces. Meanwhile, the number for a thickness of 10 cm is 83 pieces. Since the only difference is the thickness, the two types of hebel sizes per square meter are the same, which is 8.3 hebels.
