Under pressure
Twenty-pound concrete cylinder samples are taken from various construction locations around base are tested to ensure the concrete can withstand the pressure of 6,000 pounds per square inch for flightline uses and 4,500 psi for building foundations Feb. 21 at Balad Air Base, Iraq. These tests confirm aircraft or buildings can be put on concrete surfaces without the concrete cracking or sinking. The cylinders are cured for 24 hours and then placed in a water bath for seven days before putting them though a strength test machine. On Feb. 21, a sample from the new Housing 6 area shoppette was tested and passed the strength test. (U.S. Air Force photo/Senior Airman Julianne Showalter)
