The invention discloses a carbonized recycled aggregate concrete production system and method.The system comprises a coarse aggregate carbonization device, a fine aggregate carbonization device, an ingredient storage device and a concrete stirring device, and a first carbonization ventilation pipeline of the coarse aggregate carbonization device is used for guiding cement kiln tail gas of a cement plant into a coarse aggregate carbonization bin; a second carbonization ventilation pipeline of the fine aggregate carbonization device is used for guiding cement kiln tail gas of a cement plant into a fine aggregate carbonization bin to produce carbonized and regenerated fine aggregate, and the concrete stirring device stirs the carbonized and regenerated coarse aggregate, the carbonized and regenerated fine aggregate and concrete ingredients. According to the present invention, the recycled coarse aggregate and the recycled fine aggregate are subjected to carbonization treatment to produce the carbonized recycled aggregate concrete, such that the performance indexes of the recycled coarse aggregate and the recycled fine aggregate can be improved through the carbonization treatment so as to obtain the large-batch carbonized recycled aggregate concrete without material selection, such that the production system provided by the present invention is significantly suitable for industrial production.

本发明公开一种碳化再生骨料混凝土生产系统及方法，系统包括粗骨料碳化装置、细骨料碳化装置、配料存储装置和混凝土搅拌装置，粗骨料碳化装置的第一碳化通气管道用于将水泥厂的水泥窑尾气导向粗骨料碳化仓内，以生产碳化再生粗骨料，细骨料碳化装置的第二碳化通气管道用于将水泥厂的水泥窑尾气导向细骨料碳化仓内，以生产碳化再生细骨料，混凝土搅拌装置将碳化再生粗骨料、碳化再生细骨料和混凝土配料进行搅拌，以生产碳化再生骨料混凝土，则通过碳化处理可以改善再生粗骨料和再生细骨料的性能指标，从而无需进行选料，并且最终可以获得大批量的碳化再生骨料混凝土，由此本发明提供的生产系统明显更适用于工业化生产。
