Concrete innovation is often evaluated as a collection of isolated technologies: a low-clinker binder, a self-healing agent, a conductive filler, or a robotic deposition process. This paper develops an integrated design framework in which these functions are selected together against strength, durability, carbon, cost, constructability, and monitoring requirements. The proposed platform combines limestone-calcined clay cement (LC3), limited biochar and recycled-mineral fractions, moisture-activated mineral or microbial healing, and a percolating carbon-based sensing network. A structured evidence review is coupled with a transparent computational scenario study. Six candidate mixtures are compared using mass-balance embodied-carbon calculations, crack-closure kinetics, resistive sensing relationships, service-life logic, and multi-objective ranking. The scenario analysis indicates that a fully integrated candidate can lower cradle-to-gate global-warming potential by approximately 38–47% relative to the reference mixture while preserving a 28-day compressive-strength class suitable for common structural applications. Healing functionality is most valuable when it delays transport-controlled corrosion rather than when surface closure alone is treated as success. Sensing functionality is shown to require moisture and temperature compensation, four-probe measurement, and calibration after cracking and healing. The paper contributes: (i) a systems architecture for multifunctional concrete; (ii) equations and decision variables suitable for optimization; (iii) a staged verification protocol spanning fresh properties, mechanical response, transport, healing, sensing, and life-cycle assessment; and (iv) an implementation roadmap for Indian infrastructure. All numerical results in the scenario section are illustrative model outputs, not claimed laboratory measurements. The framework is intended to guide subsequent experimental validation and field demonstration.
