Mixing Water for Concrete

Almost any natural water that is drinkable can be used as mixing water for making concrete. Excessive impurities in mixing water not only may affect setting time and concrete strength, but also may cause efflorescence, staining, corrosion of reinforcement, volume instability, and reduced durability. This webinar will detail the impact of mixing water on concrete properties.

At the end of this course, participants will have the ability to:

• identify the ASTM standards for concrete mixing water


• recognize the sources of mixing water


• discuss mixing water impurities and their effects on concrete properties

Upon completion of the webinar, registered participants will be emailed a copy of the presentation slides, a certificate for 0.1 CEU credit, and a PDF of “Mixing Water for Concrete”, Chapter 4 of PCA’s Design and Control of Concrete Mixtures, 14th edition, EB001.

The cost of this one-hour Webinar is $60.
$30 for PCA members; government officials (.gov); students and educators(.edu).
