Admixtures for Concrete
Admixtures are ingredients other than water, aggregate and Portland cement that are added to a concrete mixture immediately prior to or during mixing. These ingredients can be used to modify the properties of concrete by affecting its workability and set time, compensating for the effects of temperature during curing, ensuring the quality of the concrete during mixing, transport and placing, and even for adding pigment. The use of concrete admixtures is fairly standard for both residential and commercial builds. While admixtures provide benefits and solve problems when properly utilized, they may also contribute to defects if applied improperly.
This course provides an introduction to the various types and uses of admixtures for concrete. It presents the major classes and their general applications in concrete work.
