A very different building system- AAC Block

In building with AAC, most blocks are solid and uniform, but some are typically ordered with round cores approximately 3.5 inches in diameter. By aligning these cores at the corners of a building and at window and door openings, continuous vertical channels are created into which steel re-bar is placed and concrete grout is poured. At the top of a wall, specialized U-shaped blocks are used that create a continuous channel or trough into which re-bar is placed and concrete is poured—creating a structural bond beam.

Building with AAC blocks is quite different from building with standard hollow-core concrete blocks. Starting with a level footing, a thin-set mortar is laid down using a specialized toothed trowel that holds a scoop of mortar. The end of the adjoining block is also buttered with the mortar. The block is then set down and tapped into place with a rubber mallet.  It is so different from concrete block installation. It’s much easier to work with AAC 。In addition to standard-dimension blocks, AAC is available in a wide range of precast panels that are produced with steel reinforcement to meet specific needs.
