Aerated concrete block regeneration and preparation method

The present invention provides a reproducing aerated concrete block, the concrete powder to regenerated by treatment with 25 ~ 50% (wt) ratio of alternative renewable alternative abrasive prepared aerated concrete blocks, aerated concrete block reproduction control containing silicon in an amount of 51.9 ~ 71.6% (wt), by compressive strength, drying shrinkage and dry density tests prove reproducing are aerated concrete block matching "autoclaved aerated concrete block" (GB11968-2006) B06A3.5 B06A5.0 quality products and technical standards, water absorption is also within the normal range. Application of the production of recycled waste concrete autoclaved aerated concrete is feasible. The use of recycled aerated concrete can effectively reduce the mountain of sand or river sand mining, reduce production costs, compared with shale brick, more price advantage and environmental significance.
