Read This Before Choosing AAC Blocks as Your House Foundation!


Planning on your own house construction allows you to tailor your home to your specific needs. You'll not only have a unique experience from start to finish, but you'll be left with the home you've always dreamed of. Choosing the right type of blocks is crucial for the safety and comfort of the occupants in the future. One of the best choices is Autoclaved Aerated Concrete (AAC) Block.



What is an Autoclaved Aerated Concrete Block (AAC)?

Autoclaved aerated concrete (bata ringan / hebel) is made by a combination of the conventional concrete mixture of Portland cement, aggregate, water and a small amount of aluminium powder, acting as an expansion agent that causes the fresh mixture to rise like bread dough. Therefore, this type of concrete contains 80 percent air. To make blocks, the material is moulded and cut into precisely dimensioned units.



The advantage of using Autoclaved Aerated Concrete block

A lot of buildings, big or small, very much prefer AAC instead of concrete brick or red brick. The porous structure gives superior fire resistance. Not only that, improved thermal efficiency reduces the heating and cooling load in buildings, so the energy can be used more efficiently since less will be needed for cooling systems like air conditioners. Also when you enclose the blocks in a room for a period of time, they will suck up sound waves. This means that the room will have a nice, soothing sound coming from it. And it means that if you live in an area with loud construction or traffic noise, your home will be a nice little haven.


Despite being 80 percent air, it has great durability and dimensional stability. A cement-based material, Units are precisely shaped and conform to tight tolerances. The material is different from concrete blocks, as the blocks are made aerated. This means that air pockets are trapped in the concrete, creating a porous material that allows it to withstand much higher levels of compression and shear forces, making AAC blocks much more durable.



The disadvantage of Autoclaved Aerated Concrete block


However, with mostly empty space in each of the blocks making them similar to a sponge, their water absorption is super high. Therefore, AAC blocks installed in a high humidity environment (e.g. Indonesia with 80 to 90 percent humidity level) and in direct contact with rain will weaken its structural strength, making it more brittle, causing it to easily form cracks through the wall.



The Importance of Waterproofing Your AAC Block


When you decide to invest in your house, it makes the most sense to use AAC Block. After all, home is where the heart lives. To get the best result, you need to make your blocks waterproof. Yes, with the right waterproofing, the problems with this type of porous material is that it can be so easily absorb water will be easily solved.
