What’s Changed in ASTM C90 and TMS 602 Since 2000, and Why It Matters
While updates to ASTM C90 and TMS 602 have been in place for years, they still influence how modern masonry assemblies are specified and reviewed. Knowing where those changes occurred can help streamline plan review and inspection. 

Masonry has a long history of durable performance, but the standards that govern concrete masonry unit (CMU) construction have continued to change. As a result, ASTM C90 and the TMS…

Increased Pipe Gradient: Is it a Practical Response to Reduced Flush Volumes?
The results obtained in the research demonstrate that increasing pipe gradient can effectively compensate for the reduced hydraulic energy of modern water-efficient WC flushes.

In response to global water conservation initiatives introduced over the past few decades, the volume of water used by water closets (WCs) has significantly reduced.   In Australia, since 1990, the standard…
