Aircrete is not as strong as concrete. It . Unlike concrete, which contains materials that make it dense, Aircrete infuses air bubbles or styrofoam beads to make the concrete less compact and lighter.This guide will help you determine whether aircrete comprises versatile features that could eventually replace concrete in building construction projects. So read on.
How Strong Is Aircrete?Autoclaved Aerated Concrete, which is also known as or Aircrete, is a conventional concrete that includes a mixture of sand, fly ash, lime, gypsum, cement, aluminum powder, and water. The goal of aerated concrete is to displace concrete with air. In the mid-1990s, Aircrete was regarded as weak, non-durable, and contained high shrinkage characteristics. The reason is the unstable foam bubbles that occurred when producing very low-density foam concrete, which was less than 300kg/m3. Conversely, the proper development of Aircrete must ensure that the air entrained into the formed concrete is very tiny, even and has consistent bubbles. The mixture must also remain intact and isolated so as not to increase the permeability of the cement paste between the voids. The density of the foam is crucial in making high-quality Aircete. The foam must be long-lasting, firm, and should not dissolve too quickly; otherwise, it would collapse. Commercial protein-based foaming agents produce better quality foams for making Aircrete. The foam is agitated by a foaming agent with compressed air to make Aircrete. Synthetic-enzyme based foaming agents and foam stability have added significant value in the stability of Aircrete. Further, specialized foam generating, mixing, and pumping equipment used in the production of foam concrete have improved the product making it possible to manufacture 75 kg/m3 density blocks. Conversely, dry densities of 400 to 1600 kg/m3 (about 25 lb/ft3 to 100lb/ft3) make foam concrete. However, Aircrete varies in density depending on the application from 12.5 lb/ft3 to 100 lb/ft3.
Why Aircrete Is Not As Strong as ConcreteLighter density foam concrete cuts into different sizes with a hand saw to desired proportions. Also, unlike standard concrete, Aircrete is easy to drill and carve, making it easy and fast for a construction worker to handle. Prefabricated foam concrete structures have a smooth finishing, which reduces plastering and labor costs. Aircrete features thermal and acoustical insulation properties that make it very different in application than standard concrete. These properties make it ideal for various purposes like insulating floors, roofs, and trench reinstatement. It also eliminates the thermal bridge, which allows the flow of outside air in a regular concrete structure. Aircrete is less dense than concrete and lightweight, making it less tiring to work with when building. Conversely, Aircrete blocks are fire-resistant and waterproof and cannot rot or decompose in water. As the world continues in its commitment to replace harmful building materials with more eco-friendly ones, Aircrete features a low environmental impact making it an excellent non-toxic building material.
Recommended Projects for AircreteToday, prefabricated aerated concrete is used extensively in commercial buildings, schools, apartments, highways, and industrial projects in the USA, a few European countries, India, Malaysia, Mexico, and several African countries. Here are a few building projects that can utilize Aircrete:
- Prefabricated insulation boards
- Bridge embankments
- Precast blocks
- Insulating compensation laying
- Sunken portion filling
- Insulation roof floor screeds
- Pipeline abandonment
- Trench reinstatement
- Sub-base in highways
- Insulation floor screeds
- Precast wall elements
- Cast-in-place walls
- Filling of hollow blocks, etc.
