Foundation.All concrete block walls must rest on a sturdy foundation of poured concrete. RFIA will be raised to the Engineer to check the work before concreting of tiffener/bonding columns. These allow the insulating properties of AAC blocks to be continuous across the wall face and can facilitate the placing of subsequent door and window fasteners. 3.10 ‘Solid Block — A block which has solid material not less than 75 percent of the total volume of-the block calculated from the overall dimensions. 2.0 Scope This work procedure covers AAC masonry work to be executed in the substructures/super structures of different buildings as specified in the approved drawings. Autoclaved Aerated Concrete is a Lightweight, Load-bearing, High-insulating, Durable building product, which is produced in a wide range of sizes and strengths. This mortar does not require any curing post application. ECO PANEL (AAC) are also steel reinforced AAC … Speed Dry Mix - AAC BLOCK JOINTING MORTAR is a high quality Premixed mortar suitable for fixing AAC/ALC/CLC blocks. AERO BLOCK AAC Blocks Grade A. AAC consist 80% air by volume, making it lightest available walling material (Weight 1/3rd that of clay bricks).Formed as a result of reaction of Aluminum on a proportionate blend of lime, cement & Flyash, the hydrogen gas that escapes creates millions of tiny air cells giving it a strong Honeycomblike structure. Opening and odd angles should be cut with a handsaw. • Aerocon block is extremely light, just one-third the weight of clay bricks or one-fourth the density of R.C.C. AAC Block laying process is almost similar to brick masonry only a few differences are there . Step by step working guide line for AAC Blocks. The inner & outer walls are interconnected by means of … Openings. The Autoclaved Aerated Concrete (AAC) material was developed in 1924 in Sweden. AAC Bricks Installation, AAC Blocks Installation, aac block work procedure read more AAC was developed in 1924 by a Swedish architect, who was looking for an alternate building material with properties similar to that of wood – good thermal insulation, solid structure and easy to work with – but without the disadvantage of combustibility, decay and termite damage. Since all brick/block work is waterproofed plastered externally you should not be worried about the dampening of internal walls. Application Procedure. We are the only Autoclaved Aerated Concrete (AAC) provider that manufactures their product in the United States! 3.3.AAC block is laid in running bond and set out to 1.8. Ensure to read the brickwork construction procedure provided by the client ; Cement mortar ratio should be 1:6 for 9” Brickwork and 1:4 41/2” brickwork ; Mortar thickness should not be more than 10 mm between the courses and sides of the bricks; Ensure you are … 2) Smoothing over the block work: Before placing mixed mortar, apply a bonding layer of 1 to 2mm thick AAC Block Adhesive mortar using a trowel pressing down on the block work.
