Decreasing the Permeability of Concrete through better Chemistry.

Using admixtures and sealants helps reduce the permeability of precast concrete for a better lifecycle. Applications include roads, bridges, buildings, sound walls, retaining walls, utilities, water infrastructure, and wastewater systems. Presentation by professional from Concrete Sealants, Inc. towards 1 PDH with lunch from Chickfila provided.

Objectives:

1. Explain the importance of reducing concrete permeability in all types of infrastructure.
2. Describe how different aspects of concrete admixture design impact concrete permeablity.
3. Differentiate between PRAH's and PRAN's and when to use each type.
4. Explain how PRAH's work to reduce concrete permeablity.
5. List applications for PRAH's.
