concretere

Concretere is a term used in speculative design and early materials research to describe a class of concrete-like composites that integrate engineered microstructures to influence mechanical behavior. The concept envisions a cementitious matrix augmented by internal architectures or inclusions that can modify stiffness, damping, or crack propagation, potentially even in response to loading conditions.

Origin and scope: The name and idea emerged in design-science discussions about programmable matter and smart infrastructure. Concretere is not a standardized material with universal specifications; rather, it functions as a conceptual framework for exploring how concrete properties might be tunable through internal design rather than solely through mix proportions.

Typical characteristics: In imagined implementations, concretere combines a cementitious matrix with structured reinforcements, microchannels, or lattice networks. Such features could enable adjustable stiffness, improved fracture resistance, and localized self-healing through encapsulated healing agents or autonomous repair mechanisms. The goal is a concrete that can adapt its behavior to different service conditions or repair demands.

Manufacturing considerations: Prototypes are described as feasible through advanced mixing techniques, additive manufacturing of lattice scaffolds, or the integration of pre-formed microstructures with cement paste. Realizing consistent performance would require new testing standards to account for anisotropy and non-uniform internal architectures.

Applications and outlook: Proposed uses include adaptive civil infrastructure, retrofit solutions, and performance-based design. Challenges include higher material costs, establishing reliable performance metrics, durability questions, and regulatory acceptance, all of which would shape future development and adoption.
