Concrete Cylinder Break

Alex Gandy & Jordan Littlepage filled the concrete test cylinders on the first pour day, April 10th, 2012. The cylinders were placed in a curing tank of water where they rested for 7 days until the first break. The next and final break will be at 14 days. The cylinder partially out of the water was the actual cylinder that Carmichael Construction Testing broke.


The Break Card below shows the date received and age of the break, the slump of the mixture prior to adding water on site, the psi of the concrete made, and what the concrete was used for.


The concrete cylinder took 4,754 psi to break the cylinder into a type three break. This is the most common break with the type of concrete we used.
