In Admixtures for Concrete , you'll learn ...
- The reasons admixtures are used and the desired results of the admixtures
- The most common admixtures and specific comments about their use, their relative strengths and weaknesses
- ASTM Standard C494, "Standard Specification for Chemical Admixtures for Concrete
- Corrosion inhibiting admixtures and why they may be worth their relatively high cost
Overview
To meet the Ohio Board's intent that online courses be "paced" by the provider, a timer will be used to record your study time. You will be unable to access the quiz until the required study time of 50 minutes has been met.

An admixture is a material added to the batch of concrete before or during its mixing to modify its freshly mixed, setting or hardened properties. About 80% of concrete produced in North America has one or more admixtures. And 70% of the concrete produced contains a water-reducer admixture. You can easily see the importance of these products for today’s engineers.
One very common admixture is used in about 40% of ready-mix products. This course will reveal the substance, its source, and the reason it is such a predominant admixture. It will also discuss the two main groups of admixtures and the effects of many of the most common of these substances.
Even if you work with concrete on only an occasional basis, the information contained in the course will help you to better understand the product and its use.
