Concrete

Chemical admixtures are materials in the form of powder or fluids that are added to the concrete to give it certain characteristics not obtainable with plain concrete mix In normal use, admixture dosages are less than 5% by mass of cement and are added to the concrete at the time of batching/mixing [37] (Admixtures are additions to a concrete mix that can help control the set time and other aspects of fresh concrete Common admixtures include accelerating admixtures, retarding admixtures, fly ash, air entraining admixtures, and water-reducing admixtur.
