Concrete admixtures influence the kinetic of cement hydration mainly during the dormant period. The dominant influence of admixtures seems to lie in different bound forces between dissociated ions in the pore water solution.
Concrete Scientific Principles matse1matseillinoisedu. The dormancy period can last from one to three hours During this period the concrete is in a plastic state which allows the concrete to be transported and placed

Chemistry of Hydration - It is assumed that each compound hydrates independently of others in Portland cement. This is not completely true because interaction between hydrating compounds will affect the mix.
