The invention provides a method and system for the autonomous management of fresh concrete properties via an autonomous processing core (APC) functioning as an extended production line. The system utilises multi-modal data comprising a visual primary signal and auxiliary electronic signals. By normalising data against rotational speed and volume, the APC identifies a stabilisation event representing the conclusion of at least one chemical or physical change occurring in the concrete from the onset of production and throughout its transportation, such as aggregate absorption, contaminant saturation, and initial hydration reactions, thereby completing the production of the concrete mix initiated at a stationary batching plant. A control interlock is executed for a delay interval defined by a dynamic saturation index (DSI) to prevent premature admixture sequestration. Following the delay, the APC directs a staged dosing protocol of incremental doses adjusted based on deviations from a target material property. Homogenisation is verified through a coefficient of variation (CoV) protocol. The system further facilitates networked fleet management, the production of both regular and special concrete mixes, 3D printing, geopolymer mixtures, cement-reduction protocols, and continuous manual remote operation of the system.
