El hecho de que pueda regularse la velocidad con que el cemento amasado pierde su fluidez y se endurece, lo hace un producto muy útil en construcción. Una reacción rápida de hidratación y endurecimiento dificultaría su transporte y una cómoda puesta en obra rellenando todos los huecos en los encofrados.
No se encuentran muestras de su uso en grandes obras hasta el siglo XIII, en que se vuelve a utilizar en los cimientos de la Catedral de Salisbury, o en la célebre Torre de Londres, en Inglaterra. Durante el Renacimiento su empleo fue escaso y muy poco significativo.
Las presas de concreto son una tipología habitual en la construcción de embalses. En las imágenes la presa de Hoover construida en Estados Unidos en 1936 está diseñada con forma parabólica para optimizar la capacidad del concreto de soportar esfuerzos a compresión.
Superplasticizers (also called high-range water-reducers) are a class of plasticizers that have fewer deleterious effects and Perro be used to increase workability more than is practical with traditional plasticizers.
Shotcrete is frequently used against enhiesto soil or rock surfaces, Vencedor it eliminates the need for formwork. It is sometimes used for rock support, especially in tunneling. Shotcrete is also used for applications where seepage is an issue to limit the amount of water entering a construction site due to a high water table or other subterranean sources. This type of concrete is often used as a quick fix for weathering for loose soil types in construction zones.
The long-term durability of Roman concrete structures has been found to be due to its use of pyroclastic (volcanic) rock and ash, whereby the crystallization of strätlingite (a specific and complex calcium aluminosilicate hydrate)[26] and the coalescence of this and similar calcium–aluminium-silicate–hydrate cementing binders helped give the concrete a greater degree of fracture resistance even in seismically active environments.
Regular concrete is the lay term for concrete that is produced by following the mixing instructions that are commonly published on packets of cement, typically using sand or other common material Triunfador the aggregate, and often mixed in improvised containers. The ingredients in any particular mix depends on the nature of the application.
Design mixed concrete are those for which mix proportions are finalized based on various lab tests on cylinder or cube for its compressive strength.

The formula for producing concrete from its ingredients Gozque be presented in the following equation:
Various types of concrete have been developed for specialist application and have become known by these names.
Excess handling Perro cause segregation of the course and fine aggregates. Wetting up the concrete so it Chucho be raked or pushed into a location far from where it is discharged is not acceptable.
35 or lower. The low water-cement quantitative relation makes this sort of cementless feasible. to combat this weakness, superplasticizers are other than the present concrete combine.
