AAC Block Quality verification on construction site

1.    Stacking ought to be done only on even as well as leveled ground surface over the 100 -200 mm for Ground Surface.
2.    Dealing with Beam with 2 number of 8 diameter reinforcement bar subsequent to 1.2 to 1.4 m height from the beginning level.
3.    Readymade jointing chemical by way of 3 to 4 mm thickness or with usual cement mortar (1:6 )

How do you maintain AAC blocks from cracking?

Some of the reasons following such cracking are deflection of beams, not level placing of blocks, structural movement because of Thermal expansion or change in damp content. One way to stay away from this is to delay the employment of the blocks till equilibrium humidity content is reached.

Is there any standard for AAC blocks?

0.3. 2 Autoclaved cellular (aerated) concrete blocks are utilized for both load bearing as well as co-ordination of requirements of a variety of types of concrete masonry units, covered under different Indian Standards.

Does AAC blocks need plastering?

The buildings constructed through AAC blocks are also acknowledged as environmentally friendly buildings as well as these buildings don't need curing and plastering.

Is curing required for aac blocks?

No curing is compulsory neither for AAC blocks or adhesive. Soaring tensile strength is accomplished in less time. Since the thickness of the adhesive is very thin, it gets rid of the shrinkage cracks in joints.

Where are AAC blocks used?

As an effect of its excellent properties, AAC is utilized in various building constructions, for instance in residential homes, commercial as well as industrial buildings, hospitals, schools, hotels and many other applications. These blocks contain 60% to 85% air by volume.
