The inherent properties of concrete masonry, including strength, durability, and fire safety, have been well documented, though a perception of high cost persists. However, due to significant changes to codes and standards that have increased the flexibility of concrete masonry systems, these systems offer cost-effective solutions. This course reviews changes to ASTM C90 and the masonry design standard and includes a discussion on the benefits and opportunities these new requirements bring.
Upon completion of this course, the Learner should be able to:
- Review recent changes to ASTM C90 (the product standard for concrete masonry units) for web requirements and compressive strength.
- Summarize research that was conducted to justify changes to the unit strength method for compliance with the specified compressive strength of masonry in Specification for Masonry Structures.
- Evaluate how increasing the base design strength of concrete masonry assemblies can lead to more efficient structural design.
- Discuss recent studies on initial cost comparisons of various construction assemblies.
