A well-executed Quality Control program is vital to the success of any precast operation. This Quality Control course will present a number of topics that will build on the National Precast Concrete Association’s Quality Control Manual. Attendees will examine concrete on a microscopic level to learn about the different kinds of pores and the hydration process. Coursework covers aggregate gradation analysis, aggregate moistures, hot and cold temperature concreting, testing for mechanical properties and durability, and analyzing trends in test data. Attendees will learn why water-cement ratio is so critical to concrete properties and the need for frequent testing to assess water absorption and movement in concrete. The Maturity Method will be presented in layman’s terms so that a precaster can accurately assess strength development and timing of manufacturing operations. A scientific calculator is needed for this course.
At the conclusion of this course, you will be able to:
- Explain concepts of porosity and permeability and how they relate to water-cement ratio
- Describe the influence of proper aggregate gradation on the long-term durability of concrete
- Define variability and decrease it by closely monitoring and evaluating trends in material test data
- Explain concepts behind hardened concrete testing methods such as compressive strength testing
- Describe potential durability issues such as carbonation, corrosion of reinforcing and freeze-thaw damage, and explain ways to mitigate these issues
