PDH UNITS: 8

Concrete admixtures are essential components in modern concrete technology. They are chemical or mineral substances added to concrete during mixing to enhance its properties and performance. This course provides an in-depth exploration of concrete admixtures, beginning with a clear understanding of their definition and purpose. Additionally, admixture mix design parameters such as: properties, setting time, benefits and applications, dosages and testing, compatibilities, and interactivefunctions and mechanisms are discussed where they apply. List of topics:

Definition, Advantages and Purpose of Admixtures
Historical Overview and Evolution of Admixture Usage
Importance of Proper Admixture Selection
Classification of Concrete Admixtures
Types of Water-Reducing Admixtures
Types of Retarding Admixtures
Types of Accelerating Admixtures
Types of Air-Entraining Admixtures
Corrosion and Alkali-Silica Reaction Inhibitors
Natural Pozzolanic Minerals
Coloring, Shrinkage-Reducing Admixtures
Type of Superplastizing Admixtures
Types of Set Controlling Admixtures
Dosage, Selection and Testing Recommendations
Recommendations for Increasing Durability and Strength

Learning Objectives

At the successful conclusion of this course, you’ll be able to identify and discuss:

how to select the appropriate admixture for the intended application.
the various types and classifications of concrete admixtures and their purpose.
how to achieve better strength and durability from their concrete mix.
The proper dosages, applications, and testing of their new concrete mix design.

Intended Audience: This course is general in nature, and would apply as suitable continuing education for: structural, civil, geotechnical, transportation, water resources, and other engineering professionals whose job description may require a generalized knowledge in achieving better concrete mix design through the proper use of admixture constituents.
