The design begins by determining the requirements of the concrete.These requirements take into consideration the weather conditions that the concrete will be exposed to in service, and the required design strength.Properly designed SCC can save time and labor without sacrificing performance.Two important properties specific to SCC in its plastic state are its flowability and stability.Concrete mixes can also be designed using software programs.SCC looks very different from conventional concrete while mixing.Several factors must be considered when selecting a waterstop.
The earliest large-scale users of concrete technology were the ancient Romans, and concrete was widely used in the Roman Empire.
The high flowability of SCC is generally attained by using high-range water-reducing (HRWR) admixtures and not by adding extra mixing water.
The stability or resistance to segregation of the plastic concrete mixture is attained by increasing the total quantity of fines in the concrete and/or by using admixtures that modify the viscosity of the mixture.
This allows a user of the concrete to be confident that the structure will perform properly.
Various types of concrete have been developed for specialist application and have become known by these names.
