(57) The invention discloses a concrete prefabricated wallboard as well as a preparation method and application thereof. The concrete prefabricated wallboard comprises a concrete matrix layer, the regenerated gel material layer is arranged on the surface of the concrete matrix layer; a carbon absorbing layer; the adhesive layer is arranged on the surface of the regenerated gel material layer; the preparation raw materials of the regenerated gel material layer comprise silicate stone powder; the preparation raw materials of the carbon absorption layer comprise silicate stone powder and silicate aggregate; the silicate stone powder and the silicate aggregate independently comprise magnesium silicate and/or calcium silicate. The gel material regeneration layer and the porous carbon absorption layer are sequentially arranged on the concrete matrix layer, calcium-rich magnesium silicate powder in the gel regeneration layer has the effect of rapidly absorbing carbon dioxide, meanwhile, the concrete matrix layer is prevented from being corroded by carbonization of the carbon dioxide, and the durability is improved; the porous carbon absorption layer is used for absorbing carbon dioxide during long-term service and providing a decorative surface with natural rock texture, and the prefabricated wallboard can greatly absorb carbon dioxide in air during short-term and long-term service.
