Civil Engineering / KIT PULL-OUT STD


Hydraulic system for extraction tests compliant with UNI EN12504: 3

The PULL-OUT STD KIT is a complete and reliable solution to perform incredibly reliable structural investigations.
The Pull-Out extraction test is classified among the semi-destructive investigation methods and consists in the measurement of the force necessary to extract a plug (pre-inserted or post-inserted) with controlled expansion in a special hole made specifically in the concrete as established by the reference standard (UNI EN12504: 3). In this way it is possible to make an estimate of the strength of the concrete directly on site and the evaluation of the mechanical characteristics of the material.
The system can be adapted for carrying out pull tests on threaded bars, anchors and anchors of various kinds.

This product can be rented.

The mechanical properties of concrete can be determined on site by measuring the force needed to pull a metal anchor pre or post inserted.
The test is performed using a manual hydraulic pump unit with a pressure gauge that drives a hydraulic jack connected to the anchor.

The value of the force produced by the test is used later to determine parameters of concrete strength by calibration curves and/or correlating the test with other methods of non-destructive investigation.
