High Precision Autoclaved AeratedConcreate Blocks

Autoclaved Aerated Concrete High Precision Blocks (HACB Blocks) are made of siliceous and calcareous materials as the main raw materials, mixed with aerating agent and other regulating materials, and made by casting, moulding, cutting, autoclaved maintenance and other crafts with a complete appearance, precise size and excellent performance. Porous silicate rectangular blocks.
Product Details

Autoclaved aerated concrete products are lightweight, high strength, with thermal insulation, sound insulation, fire-resistant, durable, anti-freezing, seepage resistance, seismic performance, high softening coefficient, environmentally friendly and energy-saving, convenient construction at a low cost, and the surface quality is good, good load-bearing, and the hanging object does not crack, it's a new type of energy-saving building materials with good performance.

Autoclaved aerated concrete products have a wide range of uses: they can be used for internal and external walls, floor slabs, roof panels of concrete structures, steel structure houses, office buildings, factories, firewalls, blast-unloading walls, fire prevention and maintenance of beams and columns of steel structures, soundproof walls, and renovation of old buildings with additional floors.
