Advantages
- AAC has been produced for more than 70 years, and it offers several advantages over other cement construction materials, one of the most important being its lower environmental impact.
- Improved thermal efficiency reduces the heating and cooling load in buildings.
- Porous structure gives superior fire resistance.
- Workability allows accurate cutting, which minimizes the generation of solid waste during use.
- Resource efficiency gives it lower environmental impact in all phases of its life cycle, from the processing of raw materials to the disposal of waste.
- Lightweight saves cost and energy in transportation, labour expenses, and increases chances of survival during seismic activity.
- Larger size blocks leads to faster masonry work.
- Reduces project cost for large constructions.
- Environmentally friendly: It produces at least 30% less solid waste than traditional concrete. There is a decrease of 50% of greenhouse gas emissions.
- Fire resistant: As with regular concrete, AAC is fire resistant.
- Great ventilation: This material is very airy and allows diffusion of water. This reduces the humidity inside the building. AAC will absorb moisture and release humidity. This helps to prevent condensation and other problems that are related to mildew.
- Non-toxic: There are no toxic gases or other toxic substances in autoclaved aerated concrete. It neither attracts rodents or other pests nor can it be damaged by such.
- Accuracy: The panels and blocks made of autoclaved aerated concrete are produced to the exact sizes needed before leaving the factory. There is less need for on-site trimming. Since the blocks and panels fit so well together, there is less use of finishing materials such as mortar.
- Long lasting: The life of this material is extended because it is not affected by harsh climates or extreme weather changes. It will not degrade under normal climate changes.
Disadvantages
1.AAC has been produced for more than 70 years, however, some disadvantages were found when it was introduced in the UK (where cavity wall with clay brick two-skin construction has been the norm).
2.Installation during rainy weather: AAC is known to crack after installation, which can be avoided by reducing the strength of the mortar and ensuring the blocks are dry during and after installation.
3.Brittle nature: they need to be handled more carefully than clay bricks to avoid breakage.
4.Attachments: the brittle nature of the blocks requires longer, thinner screws when fitting cabinets and wall hangings and wood-suitable drill bits or hammering in. Special, large diameter wall plugs (anchors) are available at a higher cost than common wall plugs.
5.Insulation requirements in newer building codes of northern European countries would require very thick walls when using AAC alone. Thus many builders choose to use traditional building methods installing an extra layer of insulation around the entire building.
Autoclaved Aerated Concrete (AAC) Block is a light weight, multi-cell new construction material; the features include lower density, heat insulation, possibility, fire and acoustical resistant properties. AAC is made from silicon material(silica sand, or recycled fly ash) and calcium material (lime, cement), mixing with foaming additive (aluminum powder),batching with, the reaction between aluminum and concrete causes microscopic hydrogen bubbles to from, expanding the concrete to about five times its original volume. It is made into the multi-cell silicate product by the processes of molding, pre-curing, cutting, evaporating and curing.
