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
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.
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.

The addition of SP in the truck during transit is a fairly modern development within the industry. Admixtures added in transit through automated slump management system, [4] allow to maintain fresh concrete slump until discharge without reducing concrete quality.
The most common use for portland cement is in the production of concrete. [17] Concrete is a composite material consisting of aggregate (gravel and sand), cement, and water. As a construction material, concrete can be cast in almost any shape desired, and once hardened, can become a structural (load bearing) element.
The ECC material family is expanding. The development of an individual mix design of ECC requires special efforts by systematically engineering of the material at nano-, micro-, macro- and composite scales. ECC looks similar to ordinary Portland cement-based concrete, except that it can deform (or bend) under strain. [1]
Another approach involves the development of bioreceptive lightweight concrete which can be used to create living walls resisting dessiccation. Researchers at the Bartlett School of Architecture are developing materials aimed to support the growth of poikilohydric plants such as algae , mosses and lichens (organisms having no mechanism to ...
