AAC LIGHTWEIGHT BLOCK The Lightweight Block commonly known as AAC is about 1/5 lighter than concrete in volume. The thickness ranges from 50 ~ 400mm. In absence International Standards shall be followed. Lime – 8%. All rights reserved. Under such steam and pressure, sand reacts with calcium hydroxide to form calcium silicate hydrate, which gives high strength to the AAC block. Used in commercial, industrial and residential applications. 3. 2. The leading manufacturer of Precast Autoclaved Aerated Concrete Products. Clay Bricks. C595/C595M Specification for Blended Hydraulic Cements. 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. Hence AAC blocks are a more eco-friendly product for construction. (For structurally reinforced AAC product, steel rebar or mesh is also placed in mould.). The specifications of AAC blocks contains General Size,Thickness Minimum, Compressive Strength, Minimum Dry density, Thermal Resistance, Allowable Shear Stress, Sound Absorption, Fire Resistance, Thermal Conductivity, Drying Shrinkage etc. Title: Data Sheet AAC Final 1 Author: creative1 Created Date: 12/19/2016 1:57:50 PM AAC or autoclaved aerated concrete blocks are lightweight, precast green building materials used in residential, commercial, and industrial construction.This type of concrete contains 80 percent air. AAC Blocks are well suited for urban areas with high rise buildings and those with high-temperature variations. AAC has a very porous structure which is characterized by "macro" pores. C1692 Practice for Construction and Testing of Autoclaved Aerated Concrete (AAC) Masonry There is a decrease of 50% of greenhouse gas emissions. 15 ltrs of potable water. Starken AAC blocks are easy to work with and can be cut to size with a tungsten carbide-tipped handsaw. AAC Block Specifications Properties of AAC Block Specifications General Size 625 mm * 240 mm * (75-300) mm Thickness 50,75,100,125,150,200,225 Minimum Compressive Strength 3 to 4.5 N/mm2 (IS 2185) Minimum Dry density 450 to 650 Kg/m3 Thermal Resistance 0.8-1.25 per inch of thickness Allowable Shear Stress 8-22 psi Sound Absorption Up to 42 De Fire Resistance 4* Hours Thermal … The thickness ranges from 50 ~ 400mm. AAC block is a special type of concrete block made up of fine aggregates, Portland cement, water, and another expansion agent (Aluminum powder). AAC was developed in 1924 by a Swedish architect, who was looking for alternate building material with properties similar to that of wood – good thermal insulation, […] Speedy construction due to its big size, light weight & ease to cut in any size or shape, All kind of fitting and chasing possible, More due to less thickness of walling material, Approx. Each block is equivalent to 7 pieces of common brick. Product Specification. Low weight, high strength, dimensional accuracy. 5% and less. AAC Blocks are generically lightweight due to the aeration process in the concrete during production allowing it to achieve a density of 480kg/m 3. Each block is equivalent to 7 pieces of common brick. They are manufactured with advance machine and technology which uses heat and pressure method known as autoclaving to cure. So it is renamed as aerated. A low density and excellent insulation High density and lower insulation property properties due to high porosity. 50kg of AAC Block Adhesive thin bed morta r with Approx. Aluminum powder – 0.07%. Saving on Steel up to 15%. AAC has passed both the Fire Test and Hose-Stream Test sections of ASTM E119. AAC Block Production Line AAC Block are made of flyash (lime slag or sand) as main raw material,cement and lime as cementing materials,and aluminum powder as foaming agent.The main forming procedures are Material crushing,measuring,mixing,pouring,curing,cutting and steaming.As a new wall body material with the characteristics of light weight, heat preservation,energy saving,waste … As we know, wood has good thermal insulation, solid structure, and easy to work, combustible, decay, and termite damage. Mixing : Use approx. PARTICULAR SPECIFICATIONS MASONRY WORK – CONCRETE BLOCK WORK 1.0 INDIAN STANDARDS: Work shall be carried out to Indian Standards and Code of practices. 3701 CR.

AAC Block Specifications Composition. It has a density of 600kg/m3 and is particularly lightweight. Our AAC range is produced as a block. Follow ANSI Specification AN-3.8 ³Requirements for Expansion Joints ´ or TCA Detail EJ171 ³Expansion Joints ´. Contact Info. Therefore, absorption of water into the AAC material is minimal. The AAC Blocks made by us at Aercon India are manufactured by combining Fly ash, Cement, Lime, Gypsum, Aluminium Powder & Water. 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. Manufacturer of AAC Block - Autoclaved Aerated Concrete Block, Rectangular AAC Block, Infitech AAC Blocks and 4 Inch AAC Block offered by Infitech Group, Pune, Maharashtra. Standard size of AAC block & price in india AAC block size in india:- AAC Block size in India are regular size is 600 mm × 200 mm × 100 mm and in inches is 24″ × 8″ × 4″ (length × height × width).
