Cement and Concrete Mineral Admixtures

Preference :

An admixture is broadly defined as something that is mixed together. Many of the additional materials that are being used in cement and concrete may be considered as admixtures according to this broad definition since they are mixed together either with cement or concrete. However, more explicit terms are being used in cement and concrete terminology. An admixture, as defined by the ACI Committee 116, is a material other than water, aggregates, hydraulic cement, and fibre reinforcement, used as an ingredient of a cementitious mixture to modify its freshly mixed, setting or hardened properties and that is added to the batch before or during mixing’. Materials of similar nature are called additions if they are incorporated into hydraulic cement during manufacture either by intergrinding or blending (ACI 116, 2005). Both of these terms embody a very wide range of materials some of which are commonly used while others have only limited applications.
