Is water curing required for AAC blocks?

This is because there is no requirement of water curing. AAC blocks are extremely resource efficient and environmental friendly material.

Do you need to wet bricks before laying?

One should remember that not all bricks need to be dampened before laying, in actual fact, pressed or extruded bricks of low porosity should never be dampened before the bricklaying process as they naturally have a reduced water uptake that, if dampened, would result in the brick retaining a thin film of water on all …

Why does AAC block float on water?

AAC blocks are somewhere from 450 kg per cum till 850 kg per cum and water is 1000 kg per cum. When we put a AAC block in water, it wont get immersed into it due to its light weight and it starts floating on the water surface, though some part of AAC block get immersed into water.

Why the bricks are soaked in water before its use?

When brick is soaked in water, the brick absorbs water and release air so that when it is used in masonry and placed over the wet mortar, it will no more absorb any water from the wet mortar. Thus, it will fail to make a strong bond between bricks and mortar.

What are AAC bricks?

AAC bricks are in high demand, owing to their high strength, load-bearing and thermal insulation properties. In the early 1920s, Dr Johan Axel Erikkson, along with Professor Henrik Kreuger, developed AAC blocks. After patenting the manufacturing process in 1924, AAC blocks were produced in full swing from 1929 in Sweden.
