Asked Questions


  • No.AAC construction provides a solid, monolithic wall system with an enclosed,non-connected cellular structure. Exterior finishes are designed to complementthis structure, providing a healthy balance between moisture resistance andvapor diffusion. The positive pressure of the air conditioning system pusheswater vapor out through the walls, while preventing moisture penetration fromthe outside.
  • Dueto it's dimensional accuracy and light weight, AAC Blocks require littletraining to an unskilled worker and thus give returns by saving in labour timeas well as ease of construction.
  • Easily.There are standard methods for installing wiring in autoclaved aerated concretewalls. Many installers use a combination. Routing: Build the walls first. Theelectrician draws directly on the block to indicate where the wires will go.The AAC installer uses a manual or electric router to cut channels on theinside of the walls. After the electrician installs the wiring, the wall isplastered or filled with our special E-Repair mix which allows a clean crackfree smooth finish to wall. Requires no pre-planning, and changes are easilymade. Conduit usually required. Extra switches and receptacles can still beadded by the routing method.
  • Non-pollutingManufacture- Autoclaved aerated concrete manufacturers use a closed-loopmanufacturing process, so that nothing is ever released other than clean steam.Product trimmings, slurry and water are reprocessed, and steam is reusedwhenever possible. Resource Efficiency- The end product is approximately 80%entrained air and 20% mass. Thus 5 parts AAC are produced from just 1 part rawmaterials. Low Energy Consumption throughout Lifecycle- The total energyconsumption to produce AAC is 1/3 to 1/2 that of comparable building materials.When installed, AAC results in tremendous energy savings for heating andcooling the building. Healthier Indoor Air Quality- AAC products are anexcellent choice for the chemically sensitive because autoclaved aeratedconcrete does not offgas. bozulanadoes not promote the growth of mildew and mold, and cannot be infested bytermites. Rats and other pests find no home, since there is no cavity in an AACwall. Pestacides can be reduced, and the occupants can breathe easier.
  • Bozlulanamaterials are environmentally-friendly, and LEED does recognize this. Pleasenote however, that LEED certification is based on the construction project, nota single material. LEED recognizes autoclaved aerated concrete products in thefollowing manner: Recycled content (applicable to buzlana blocks containing fly ash); Reduced energyconsumption; locally sourced products (if applicable to project), and locallysourced raw materials.
  • Althoughthe mix of buzlana Blocks and concrete blocks or bricks is not required in mostcases, there is no technical restriction to prohibit the use of both products.Also, there's no technical issue raised, if you decide to change the materialto Citadel bozula Blocks, even if not planned initially.
  • R-Valueis measure of apparent thermal conductivity and thus describes the rate thatheat energy is transferred through a material of assembly regardless of itsoriginal source. R value is a measure of the resistance of building materialsand structures to the flow of heat; the higher the R-value the better thesubstance is as thermal insulation. The thermal performance of AAC isequivalent to R-20 insulation. AAC combines the advantage of low thermalconductivity and low air-infiltration with high thermal mass. This product isused in every climatic region of the world, from humid South America , tothe dry heat of the Middle East and the severe cold of Finland. Insulationis rarely added; the walls are simply thicker. A 200mm thick AAC wall gives anR-Value rating of 0,95 for bozulanawith 5% moisture content by weight.
  • Manyof the conventional exterior finishing systems such as one coat plastering(sometimes referred to as a hard coat system) and two coat systems can be usedover bozulana Blocks as an exterior finish. Otheroptions such as our RTU Eco Render pre mixed wet rendering adhesive, brickveneer, stone and siding can be used and have been used inmany residential/commercial & industrial projects.
  • Yes.Gypsum board or sheetrock may be attached directly to bozulana walls withconstruction adhesive and screws, or it can be attached to furring strips. TheAAC should be dry before the sheetrock is applied
  • Thefirst course of blocks are always laid in thick bed mortar mix made of 1:4 (byvolume) cement: sand added to it as a bonding agent @ 10% of water. This servesas a leveling pad for the first course of blocks. Care must be taken at thisstage to ensure the blocks are plumb and level so further construction up toceiling height will be fast and accurate. The second and successive bed jointsmay use thin-bed mortar, which is a pre ploymerised & is a non cement-basedproduct and inorganic fillers such as flyash etc. Head joints always usethin-bed mortar. When thin-bed mortar is used, a joint thickness of 1/16-1/8inch is realized.
  • Thin-bedmortars marketed exclusively by Citadel, is designed especially for AAC &is used to install the AAC blocks and lintels. It is sold in ready-to-use premixed wet form. Bozulana Binder/mortaris pre-polymerised using flyash as filler & is specifically designed tobond AAC blocks or panels for interior and exterior wall construction. Just 1/8inch mortar bed is needed to adhere the products. This extremely thin jointprevents heat loss and speeds installation. For best results, apply thin-bedmortar with a notched trowel. For AAC block installation, choose a trowel thesame width as the block. The unique property of the RTU- Mortar is that u donot need to pre wet the blocks or post cure the mortar as is required by allconventional mortars. The product is eco friendly & qualifies as a GreenProduct and has near to Zero VOC. There is NO cement used in the mortar &has a bonding strength almost 5 times as that of conventional mortar.
  • ThinBed Mortar namely AAC Binder/Mortar, is a specially developed thin jointinsulating mortar for Autoclaved Aerated Concrete Blocks. It ensures that jointwidth is kept to a minimum hence eliminating the cause of thermal bridgingassociated with the use of traditional mortars. So, it is important that AACblocks for external walls should be laid using thin bed mortar recommended bythe manufacturer of AAC Blocks and this mortar should be used for bothhorizontal and vertical joints of approx. 3 mm thick to prevent any thermalbridging through non-filled joints. Also the same should be used for theinternal block walls to prevent any effects of the performance of wall's soundinsulation through the non-filled joints.
