The invention relates to an integrated production line for preparing concrete products, which includes a cementitious material preparation system, a concrete mixing system, and a concrete product molding system that are arranged in sequence. At the same time, the system can be used to produce lightweight wall materials, marine engineering products and Different types of products such as municipal parts can realize the multifunctional use of preparing lightweight concrete products and high-strength concrete products. Using this system to prepare concrete products can not only reduce land occupation and investment, reduce production and transportation costs, but also effectively keep materials fresh It can control product quality, and can produce differentiated products with special performance in a targeted manner.
