Aluminum powder – 0.07%. Thin-bed or Thin-joint mortar is applied at a thickness of 2 ~ 3 to the entire area of the joint surface using a notched trowel to … Cement (usually OPC grade 53) -33%. Cost. Starken AAC blocks are easy to work with and can be cut to size with a tungsten carbide-tipped handsaw. The low density is achieved by the formation The concrete so formed has a high density and of air voids to produce a cellular structure. Low weight, high strength, dimensional accuracy. Lime – 8%. Installation during rainy season leads to crack after installation. 2 to 6 (Depending on Thickness) 2: Thermal Conductivity “K” The AAC products not only include AAC block, but they also include wall panels, floor and roof panels, lintels, etc. 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. The Lightweight Block commonly known as AAC is about 1/5 lighter than concrete in volume. After mixing, this concrete is poured into the mould of standard size. … AAC ranges in density from 25 to 50 lb/ft3with compressive strengths ranging from 290 psi to 1090 psi, and is well suited for both loadbearing and non-loadbearing walls. Resistant to termite attacks: Autoclaved Aerated Concrete (AAC) Block consist of the inorganic material in its constitution which helps to avoid termites attacks that happen in the case of clay bricks. AAC blocks are precast, lightweight autoclaved aerated concrete and is a concrete building material which is used for producing concrete masonry units like blocks & under heat and pressure, AAC products are cured and composed of quartz sand, lime, water, cement, aluminum powder and calcined gypsum. Zero Saving. They are normally 9-12 kg in weight depending upon moisture conditions. Product Specification. But AAC blocks minimize the disadvantage of using timber as a construction material. (For structurally reinforced AAC product, steel rebar or mesh is also placed in mould.). However, labor costs for AAC can be lower because its lighter weight makes it easier to handle and install. List given hereunder is not to be considered as conclusive and is for reference and guidance only. AAC block is a special type of concrete block made up of fine aggregates, Portland cement, water, and another expansion agent (Aluminum powder). Then, the hydrogen gas escape by leaving voids in between concrete, and this mould is removed and cut into small pieces (Waste during cut can be recycled). Advanced Audio Coding (AAC) is an audio coding standard for lossy digital audio compression.Designed to be the successor of the MP3 format, AAC generally achieves higher sound quality than MP3 at the same bit rate.. AAC has been standardized by ISO and IEC as part of the MPEG-2 and MPEG-4 specifications. Requires less due to flat, even surfaces & less number of joints. 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. ASTM C1660 Standard Specification for Thin-bed Mortar for Autoclaved Aerated Concrete (AAC) Masonry ASTM C1691 Standard Specification for Unreinforced Autoclaved Aerated Concrete (AAC) Masonry Units 2. The AAC Blocks made by us at Aercon India are manufactured by combining Fly ash, Cement, Lime, Gypsum, Aluminium Powder & Water. Starken AAC blocks are easy to work with and can be cut to size with a tungsten carbide-tipped handsaw. C1692 Practice for Construction and Testing of Autoclaved Aerated Concrete (AAC) Masonry 1. 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 … 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, […] significantly reduced heating and cooling cost. C150 Specification for Portland Cement. Easy laying and workability. We manufacture the AAC blocks in a variety of sizes. 3. On … Reduces a dead load of building on the foundation. Copyright © 2013 Eco Green. When we mix the aluminum powder with silica or other material containing silica, there is the formation of hydrogen gas. The temperature of autoclave has reached about 190° Celsius and pressure about 8 bars to 12 bars. Let us start from the introduction of AAC blocks. 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.

Take water in the container and slowly add the powder into the water while mixing by hand or slow speed mixing machine. They are manufactured with advance machine and technology which uses heat and pressure method known as autoclaving to cure. The combustible, decay, and termite damage can be totally removed using this block. 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. AAC LIGHTWEIGHT BLOCK The Lightweight Block commonly known as AAC is about 1/5 lighter than concrete in volume. When the foaming agent is diluted with water and air, further it is mixed into the cement slurry. 4. Sound Proof: AAC blocks have been an ideal material for the construction of walls in the auditorium, hotels, hospitals, studios, etc. What Is AAC Block? Follow ANSI Specification AN-3.8 ³Requirements for Expansion Joints ´ or TCA Detail EJ171 ³Expansion Joints ´. Suitable for use in areas with extreme temperatures. So it is renamed as aerated. What are Biltech ACE blocks/panels made of? Download Brochure here. In the factory where it is produced, the concrete is molded and cut into precisely dimensioned masonry blocks or formed as larger planks and panels. Brikolite Sizes. Each block is equivalent to 7 pieces of common brick. 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. AAC blocks are made by Fly ash or Pond Ash or Sand via a non-polluting process of steam curing comprising of non¬toxic elements. Thin-bed or Thin-joint mortar is applied … Continue reading "AAC Lightweight Block" Do not cover expansion joints with mortar. AAC is well suited for high-rise buildings and those with high-temperature variations. Product Specification. Mixing : Use approx. Breakage. Therefore, absorption of water into the AAC material is minimal. specification for concrete masonry units part 3 autoclaved cellular (aerated ) concrete blocks ( first revision ) first reprint december 1989 udc 693.5:692,327.332-437 i .
