Admixtures for Concrete

This PDH online course is a part of the Civil Engineering course category. This course gives guidance on using of concrete admixtures to ensure quality and appropriate concrete properties are achieved during design and placing of concrete mixes. Admixtures are those ingredients in concrete, other than portland cement, water, and aggregates that are added to the mixture immediately before or during mixing. Concrete should be workable, finishable, strong, durable, watertight, and wear resistant. These qualities can often be obtained easily and economically by the selection of suitable materials rather than by resorting to admixtures (except air‐entraining admixtures when needed).

Major reasons for using admixtures are:

  1. To reduce the cost of concrete construction
  2. To achieve certain properties in concrete more effectively than by other means
  3. To maintain the quality of concrete during the stages of mixing, transporting, placing, and curing in adverse weather conditions
  4. To overcome certain emergencies during concreting operations

This course is intended for use by civil engineers, materials scientists / engineers, chemical engineers, construction professionals and others interested in learning about concrete admixtures.
