Lightweight Concrete is concrete with a density that is lighter than concrete in general. Lightweight concrete can be referred to as aerated lightweight concrete (ALC) or called (Autoclaved Aerated Concrete / AAC), which has the primary raw material consisting of silica sand, lime, cement, water, plus a developer material which is then treated with water vapour pressure. Unlike ordinary concrete, the weight of lightweight concrete can be adjusted as needed. In general, the weight of lightweight concrete ranges from 600 – 1600 kg/m3. Therefore, the main advantage of lightweight concrete is its weight, so if it is used in high-rise building projects, it will be able to significantly reduce the building’s weight, which in turn impacts foundation calculations.
There are several advantages of lightweight concrete or Autoclaved Aerated Concrete (AAC), namely:
• AAC blocks are easy to shape. So it can be quickly and accurately cut or shaped to meet the demands of building decoration. The tools used are simple, just use carpentry tools. Find out more about light weight concrete selangor.
• Because the size is accurate but easy to shape, it can minimise the remnants of unused building materials.
• AAC can simplify the construction process. To build a building, the products that will be used can be minimised. For example, there is no need for stones or gravel to fill a concrete floor.
• Its light weight reduces transportation costs. Moreover, the AAC factory was built close to its consumers.
• Because it’s light, builders don’t get tired quickly. So fast in the process.
• The special cement is only 3 mm long.
In addition to the advantages, AAC Concrete also has several disadvantages:
• Due to its large size, it will consume a large amount of waste for a moderate size. Therefore, additional expertise is needed …
