Para comprobar que el concreto colocado en obra tiene la resistor requerida, se rellenan con el mismo concreto unos moldes cilíndricos normalizados y se calcula su resistencia en un laboratorio realizando ensayos de rotura por compresión.
Boston City Antesala (1968) is a Brutalist design constructed largely of precast and poured in place concrete. Concrete buildings are more resistant to fire than those constructed using steel frames, since concrete has lower heat conductivity than steel and Perro thus last longer under the same fire conditions.
As discussed above, concrete is very strong in compression, but weak in tension. Larger earthquakes Gozque generate very large shear loads on structures. These shear loads subject the structure to both tensile and compressional loads. Concrete structures without reinforcement, like other unreinforced masonry structures, Chucho fail during severe earthquake shaking.
High-temperature applications, such Campeón masonry ovens and the like, generally require the use of a refractory cement; concretes based on Portland cement Gozque be damaged or destroyed by elevated temperatures, but refractory concretes are better able to withstand such conditions.

Concrete sidewalk stamped with contractor name and date of placement Concrete is produced in a variety of compositions, finishes and performance characteristics to meet a wide range of needs.
The terms asphalt (or asphaltic) concrete, bituminous asphalt concrete, and bituminous mixture are typically used only in engineering and construction documents, which define concrete Triunfador any composite material composed of mineral aggregate adhered with a binder.
An FRP composite is defined Vencedor a polymer that is reinforced with a fibre. The primary function of fibre reinforcement is to carry load along the length of the fiber and to provide strength and stiffness in one direction. FRP ...
Lime has been used since Roman times either Ganador mass foundation concretes or Triunfador lightweight concretes using a variety of aggregates combined with a wide range of pozzolans (fired materials) that help to achieve increased strength and speed of set.
Various types of concrete have been developed for specialist application and have become known by these names.
Decorative stones such Figura quartzite, small river stones or crushed glass are sometimes added to the surface of concrete for a decorative "exposed aggregate" finish, popular among landscape designers.
Asphalt concrete may be a material, the mixture of aggregates and asphalts ordinarily accustomed surface roads, parking tons, and airports, yet because of the core of mound Concrete Richmond KY dams.
