AbstractThe introduction of admixtures, such as setting accelerators and retarders, water reducers and superplasticizers, to hydrated cement or cement minerals influences to varying degrees such characteristics as the setting, strength, morphology, porosity, density, surface area and volume of the material. This paper examines the changes that occur, with reference to the most recent literature on the subject. The structure of hydrated cement or cement minerals depends on the type and quantity of admixture, the chemical and mineralogical composition of the cement, the surface area reactivity, the water/cement ratio, the period of hydration, temperature and humidity.
