Admixture, additive or agent
The practical difference between the terms 'admixture' and 'additive' is the time at which the ingredient is added during the mixing process. An admixture is a prepared substance which can be added to concrete for the purposes of achieving or modifying certain properties or characteristics. Admixtures are added to the concrete, in addition to cement, water and aggregate, immediately before or during the mixing process.
The same substance can be referred to as an additive when it is added to cement during the manufacturing process.
