[19] Its widespread use in many Roman buildings, a essential function inside the history of architecture termed the Roman architectural revolution, freed Roman construction with the limits of stone and brick elements. It enabled innovative new layouts when it comes to equally structural complexity and dimension.[twenty] The Colosseum in Rome was developed mostly of concrete, and also the Pantheon has the whole world's most significant unreinforced concrete dome.[21]

For increased-strength apps, accelerated curing methods may very well be applied to the concrete. A standard procedure requires heating the poured concrete with steam, which serves to both hold it damp and lift the temperature so which the hydration course of action proceeds a lot more rapidly plus much more completely.
Concrete formwork is usually geared up Concrete in many methods, such as slip forming and metal plate design. Alternatively, concrete could be blended into dryer, non-fluid types and Utilized in factory options to manufacture precast concrete products and solutions.
