A concrete category is a pair (C,U) such that . C is a category, and; U : C → Set (the category of sets and functions) is a faithful functor.; The functor U is to be thought of as a forgetful functor, which assigns to every object of C its "underlying set", and to every morphism in C its "underlying function".

These categories of materials and products are used by architects and construction project managers to specify the materials and methods used for building projects. Some building materials like cold rolled steel framing are considered modern methods of construction , [ by whom? ] [ clarification needed ] over the traditionally slower methods ...
Researchers have tried to sequester CO 2 in concrete by developing advanced materials. One approach is to use magnesium silicate as an alternative to calcium. This lowers the temperature required for the production process and decreases the release of carbon dioxide during firing. During the hardening phase, additional carbon is sequestered.
