Hence ...
Admixtures are used in concrete to alter its properties in various ways. Some common uses include improving workability, increasing or decreasing cure time, and increasing concrete strength. Admixtures can also be used for aesthetic reasons, such as to change the color of the cement.
Accelerating Admixture - an admixture that causes an increase in the rate of hydration of the hydraulic cement and thus shortens the time of setting, increases the rate of strength development, or both. Accelerating admixtures are added to concrete either to increase the rate of early strength development or to shorten the time of setting, or both.

Admixtures are natural or manufactured chemicals which are added to the concrete before or during mix- ing. The most often used admixtures are air-entraining agents, water reducers, water-reducing retarders and accelerators.
In order to produce concrete with a lower water-to-cement ratio, chemical admixtures can reduce the required amount of mixing water and still obtain the desired fresh properties to facilitate the placement and consolidation of the concrete. One of the key parameters in producing high-strength concrete is the use of a low w/c ratio.
