The human cardiovascular system, which conducts blood throughout the body, and the plant vascular tissue system, which transports food, water, and minerals via xylem and phloem networks, are examples of vascular network systems. Similarly, vascular networks in concrete may transport liquid healing chemicals to damaged areas.
A living building material (LBM) is a material used in construction or industrial design that behaves in a way resembling a living organism.Examples include: self-mending biocement, [1] self-replicating concrete replacement, [2] and mycelium-based composites for construction and packaging.
A single concrete block, as used for construction. Concrete is a composite material composed of aggregate bonded together with a fluid cement that cures to a solid over time. . Concrete is the second-most-used substance in the world after water, [1] and is the most widely used building material
Some skin secretions are associated with body hair. Skin secretions originate from glands that in dermal layer of the epidermis.

They function as dispersants to minimize particles segregation in fresh concrete (separation of the cement slurry and water from the coarse and fine aggregates such as gravels and sand respectively). The negatively charged polymer backbone adsorbs onto the positively charged colloidal particles of unreacted cement, especially onto the ...
In order to avoid frequent cleanings of new church's concrete "sails", new development was used - white self-cleaning coating of the walls. [3] However, back then it wasn't known that this colouring plaster containing titanium dioxide and white pigment absorbs exhaust gases and other elements of city fog.
