October 13, 2022

The two most common tests of new concrete include the strength of a sample of concrete tested usually at 28 days and testing the air content of the fresh concrete on-site as the construction is progressing. But which one of these tests is more important? Which one should we pay more attention to?

Concrete and Rain
August 8, 2022

We get it, weather in Michigan can have a mind of its own. This can be a real struggle when dealing the ever-changing conditions.
