AAC Block Production Line

Lontto have 20000~250000 m3 per year Light Weight AAC Blocks Making Automatic Concrete AAC Block Production Line

  • First, dose and match measured raw materials;
  • After distributing, feed raw material into pouring mixer to make slurry.
  • Through thoroughly mixing, the slurry is poured to mould;,

AAC block production line is produced out of a mix of cement, lime, fly ash, gangue, river sand and aluminium powder ect., through batching, mixing, casting ,cuttimg and autoclaving. AAC has the advantages of extremely light weight, high compressive strength, excellent thermal insulation, great scousitc insulation and high fire resistance. AAC can be produced in a large variety of sizes, from stand blocks to large reinforced panels, and it can be cut, sawn ,drilled ,nailed and milled like wood, making it an extremely workable product, AAC is environment-friendly and new building material.

ADVANTAGES of AAC Block Production Line:

  • Main Material: coal ash sand waste mine material coal stones tone dust and other silicon materials.
  • Lightweight: Porosity achieve 70% to 85%, volume density is generally 500 ~ 900kg/m3, as 1/5 of general concrete the 1/4of clay, the 1/3 of hollow brick, and similar with wood can float in water. It can reduce building weight, reduction in the cost of integrated building.
  • Fireproof: Most of the major raw materials is inorganic materials, so it has good fire resistance, and do not emit harmful gases when meet fire. Fire 650 degrees, as a refractory material, the thick up of 90mm walls can reach to 245 minutes fire resistance, 300mm thick up wall can reach to 520 minutes fire resistance.
  • Sound insulation: Due to a unique porous structure, so it has a sound absorption capacity. The sound absorption capacity can reach of 10mm thick wall up to 41 db.
  • Insulation: As the material inside has a large numbers of the pores and porous, which has a good thermal insulation properties. The Thermal conductivity is 0.11-0.16W/MK, as 1/4-1/5 of brick. Typically, the insulation effect of 20cm thick aerated concrete wall is equivalent to 49cm thick solid brick walls ordinary.
  • Permeability: Result of material by the composition of many independent small pores, the moisture absorption is slow, in the volume of absorbent is 5 times of clay saturation do. When used in the bathroom, the wall can be treated to interface directly paste tiles.
  • Anti-seismic: The same building structure, improve the two seismic than the brick level.
  • Green: Manufacturing, transportation, all use the process of pollution, to protect arable land, saving energy, is one kind of a green building material.
  • Durability: material strength is stability, in the specimens tested after one year of atmospheric exposure; the intensity increased by 25%, and remained stable after ten years.
  • Shortcut: it has good machinability, can be sawed, planed, drilled, nailed, and available appropriate as bonding of adhesive material, so create favorable conditions for building construction.
  • Economies: An integrated lower cost than using more than 5% of solid clay bricks, and can increase the usable area, greatly enhance the utilization of floor space.
