Autoclaved aerated concrete (AAC) is a building material which consists of various sized elements that form a complete building system. In most cases, every portion of the structural and insulation requirements of a building are satisfied with the one material.
There is a benefit in cost of around 2.5% for AAC based systems over conventional systems purely on savings on account of structural costs.
AAC based systems shall provide a time benefit of over 20% vis-à-vis conventional construction due to reduction in number of joints.
AAC based systems shall provide a major 30% saving in energy costs, AAC based systems provide high insulation properties.
As AAC offers reduced environmental impact during manufacturing, construction and renovation, it is fast emerging as a Green Building Material.
Storage of Material:
The blocks shall be stored on the site on a level ground and to be protected against rain fall and snow fall.
Mix Proportions of Mortar:
Use of strong mortar with light weight concrete blocks is not advisable, use of compatible mortar is advisable. Lean mortars distribute and accommodate more readily the strains arising from thermal, moisture and chemical changes.
Soaking and Wetting Of Blocks:
These blocks should never be soaked prior to laying in the wall. Only slight wetting is required.
Laying of Mortar:
The mortar shall not be spread so much ahead of the actual laying of the units that it tends to stiffen and lose its plasticity there by resulting in poor bond.
Laying Block Masonry :
Laying of AAC Block masonry shall be in accordance with the recommendations of IS 6041 of 1985 and IS 1905 OF 1987 .The joint thickness shall be 10 mm.
Design of AAC block masonry is based on the same parameters as that of brick masonry, as Indian Standard BIS:1905 (masonry code) applicable to brick masonry is also applicable with the same provisions to AAC block masonry. Therefore slenderness ratio of AAC masonry walls shall be as per guide lines of Indian Standard for masonry walls.
Guide lines for chases is masonry walls as per Indian Standard BIS:1905 need to be followed. The cutting of chases, recesses etc. should be done with out damage to the surrounding masonry.

AAC Masonry Useful Tips:
The mortar shall not be spread so much ahead of the actual laying of the units that it tends to stiffen and lose its plasticity there by resulting in poor bond. Consistency as per requirement of site must be maintained at the point of laying over bed. Ensure all the surfaces of the block which come in contact with cement mortar are wet to have proper bonding.
