Concrete Pumping - Why do you lose air and why does the air come back? (2023 update)
Concrete Pumping is a widely used method for concrete construction. However, pumping is known to change the air content of fresh concrete. This video uses lab and field data to verify that the air is lost and the important air, the small bubbles seem to return to the concrete before it hardens. This is an important finding and a chance to change current specifications that require air content to be measured after a concrete pump. www.tylerley.com www.tylerley.com/giving
