This test represents the horizontal portion of our piling testing. In the press is one of our 18”x18”x30’ Cor-Tuf UHPC pilings equipped with a full suite of embedded sensors prior to the start of testing.
Aerial view of the horizontal portion of our piling testing. Below, you can see a wider view of one of our 18”x18”x30’ Cor-Tuf UHPC pilings equipped with a full suite of embedded sensors prior to the start of testing.
Image above depicts the Cor-Tuf UHPC piling during testing. The center of the piling was deflected 4.5” from level center as can be seen here.
When the piling failed, it failed in one location with no extreme radiating cracking from the center. This was the only failure point on the piling.
In this test, we are installing our 18”x18”x100’ piling into the ground with the first of two hammers we used for the test, the D36. During our testing, we monitored the vertical stresses delivered to the piling during installation with a similar suite of monitoring sensors as we did in the flexural testing.
In this photo, we have just concluded the first phase of installation testing and are getting ready to switch to the larger D62 hammer. This hammer was used throughout phase two of our testing.
Here we have switched hammers to the larger D62 hammer for phase two of our installation testing. In phase two, we were attempting to break the piling by applying as much vertical force as possible to the top of the pile.
This is the top of the pile after all testing concluded. Aside from some discoloration caused by the hammer pad, the piling is otherwise in ideal condition. Regardless of which hammer was used or force exerted, the structural integrity of the piling never dipped below 100 percent.
Pictured above is the first of two pre-tensioned pilings filled with Cor-Tuf UHPC for testing by the Florida Department of Transportation and the University of Florida. Each piling measures 18” x 18” x 30’.
