The density of each block calculated as follows: Density in kg/m 3 = Mass of block in kg/Mass of block in cm 2 * 10 6. Origins. 3. Follow the checkout process, ensuring you attach your company logo in a high resolution JPEG format for inclusion in the online safe work method statement/job safety analysis. The Autoclaved Aerated Concrete (AAC) material was developed in 1924 in Sweden. Autoclaved aerated concrete (AAC) is a lightweight, precast, foam concrete building material suitable for producing concrete masonry unit (CMU) like blocks. Dry density of AAC block varies from 451 kg/m 3 to 1000 kg/m 3. Step by step working guide line for AAC Blocks. Thin joint concrete common block work shall be manufactured in accordance with BS EN 771: Part 3 and tested in accordance with BS EN 772. ECO PANEL (AAC) are also steel reinforced AAC … Basic AAC block in the standard size of 8 x 8 x 24 inches costs about $2.20 to $2.50 per square foot as of July 2018, slightly more than standard concrete block, which costs about $2.00 per square foot. However, labor costs for AAC can be lower because its lighter weight makes it easier to handle and install. Although the ASTM C426 procedure permits top and bottom gauges, they are not used very often for concrete blocks. This mortar does not require any curing post application. The width of AAC Block joints to be approximately 3mm with the mortars (as per required by the engineer). FEATURES AND BENEFITS Formulated to comply with Hence, few experiments with this kind of reading have been reported. Testing assures the quality of AAC block… Mtr: Area of the Wall : Sq.

AAC Bricks Installation, AAC Blocks Installation, aac block work procedure read more WORK PROCEDURE FOR AAC BLOCK MASONRY Work Procedure No. If multiple courses of U-Block are used, notching is required to allow concrete to get to the lowest course. Speed Dry Mix - AAC BLOCK JOINTING MORTAR is a high quality Premixed mortar suitable for fixing AAC/ALC/CLC blocks. 3.3.AAC block is laid in running bond and set out to Because of reduction in self-weight, AAC block construction attracts less earthquake load. The nominal dimensions of the units are so designed that taking AAC Block vs Brick (m²/ worker/ day) Thermal Control Built using Bricks Built using AAC Products 25% less foundation required Save up to 25% of Foundation Cost Brick vs AAC Block 1 2 3 5 Heat insulation 6 times superior than clay brick Note : Building uses approximately 30% less energy for cooling and heating the interior air space. Scope: The intention of this document is to describe the various steps involved to be carried out to execute the Block works to meet the requirements of Specifications. The depth and size of the foundation will vary depending on the size of the concrete block wall and the weight it must support, but a typical freestanding wall requires a foundation that is about twice as wide as the wall itself and which extends about 1 foot down below the frost line. 3.11 Webs — The solid sections of the hollow concrete blocks which connect the face shells. AAC blocks need to be tested in a certified lab before you construct a house. Height of the stack should not be more than one and half meter. 1. Safety and Protection Blocks shall be stacked properly near the place of work (Do not stack too large quantity near the work area thereby causing safety hazard). AERCON AAC is the leading manufacturer of Precast Autoclaved Aerated Concrete Products and prides itself on maintaining the highest level of customer service and support. It is a specially formulated mortar that replaces conventional site mixed Cement - Sand mortar. 4. Although AAC blocks are porous, the pores are not interconnected so the water absorption is relatively less as compared to clay bricks. Bond beams should be placed at the top of the wall and we can use it for heavy-duty fixture attachment. Manufacturing Process of AAC Block. 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. 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. How to Do AAC Blockwork 3. Scaffolding to be braced adequately. The inner & outer walls are interconnected by means of … First a fall, autoclaved aerated concrete is produced by mixing silica or sand or fly ash with cement, lime, water, and expansion agents such as aluminum powder. 3.2.1 The nominal dimensions of the concrete block shall be as follows: I,ength 400,5000r600mm Height 200,250 or 360 mm Width 100,150,200 or 250 mm In addition, block shall be manufactured in half lengths of 200,250 or 300 mm to corresponcl to the full lengths. The width of cavity is constant with a suitable value between 40 to 100 mm & cavity is continuous in vertical direction expect at lintel on openings. Foundation.All concrete block walls must rest on a sturdy foundation of poured concrete. Then apply AAC Block Adhesive at a thickness of 8 to 10mm and smoothen usi ng a sponge or rubber / wooden float. PROCEDURE Constructed in two leaves- inner & outer with a hollow space in between them. The low dry density of AAC blocks reduce the load on the foundation and other structural components in a structure leading to 55% reduction in weight of walls. Autoclaved Aerated Concrete is an eco-friendly and certified green building material which is lightweight, load-bearing, high-insulating, durable building blocks and 3 times lighter when compared to red bricks. Always pre-wet the u-block before pouring the grout. RFIA will be raised to the Engineer to check the work before concreting of tiffener/bonding columns. 2. could be easily used to cut and align the AAC. Application Procedure. 3.2.Adhesive is applied to AAC blocks to maintain full joints at specified thickness in accordance with manufacturer specifications. Add the safe work method statement, job safety analysis or safe operating procedure and any additional swms's, jsa's or sop's you require to the shopping cart. • Aerocon block is extremely light, just one-third the weight of clay bricks or one-fourth the density of R.C.C. 3. 3) As Adhesive to install tiles: • They are easy to install and can complete the construction procedure in a shorter span in case of scarcity of labour and in the usage of mortars. Method Statement for Block Works in a Quality Management System are given below: 1. Autoclaved Aerated Concrete is a Lightweight, Load-bearing, High-insulating, Durable building product, which is produced in a wide range of sizes and strengths. Mtr: Number of Blocks : Nos. 1.8. This pictuorial guide line easy to understand and you will get whole idea about its working. Autoclaved Aerated Concrete (AAC) is a lightweight, concrete-like material with many small, closed internal voids. As the AAC block is very easy to handle, manipulate and use ordinary tools for cutting the wood such as the drill, band saws, etc. Restraint Posts:-All restraint post around windows shall be provided as per approved shop drawings, during the AAC block work construction. The placed mixed mortar on the block work in 3mm (As per required by consultant or Engineer) using trowel and place the next layer of blocks on the mortar. We are the only Autoclaved Aerated Concrete (AAC) provider that manufactures their product in the United States! Lay AAC blockwork. AAC Block laying process is almost similar to brick masonry only a few differences are there . AAC typically weighs one-sixth to one-third as much as conventional concrete, and is … Typical block work details will be resubmitted for the Engineer approval. Since all brick/block work is waterproofed plastered externally you should not be worried about the dampening of internal walls. Openings. 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. 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. The blocks shall then be weighted in kilograms to the nearest 10 gm. Presenting 2. Aluminum powder – 0.07%.
