Many precast concrete producers have introduced supplementary cementitious materials (SCMs) as a partial portland cement replacement in their mix designs. Many are considering using fly ash or slag cement or switching from one to another. Whether you are a current SCM user or are thinking about becoming one, it’s important to know which material works best with specific product types, product exposure and current mix designs. When used in the right way, the benefits of SCMs can be significant. How can fly ash affect air entrainment? How do different grades of slag affect set times? During this webinar, we will explore these topics and many more to aid precast manufacturers in making an informed decision on the use of SCMs.
At the conclusion of this webinar, you will be able to:
- Describe how fly ash and slag cement work to contribute to hardened concrete properties.
- Explain other effects SCMs can have on plastic and hardened concrete
- Describe precautions that should be taken when combining SCMs with admixtures
