Steel Bar Pull Out Test

The tensile test of steel bar is the field test of the anchoring force.

Steel bar pull out test. Such strength relationships are affected by the configuration of the embedded insert bearing ring dimensions depth of embedment and the type of aggregate lightweight or normal weight. In fact the most common test for steel bar reinforcement is the tensile test bending test and chemical analysis. Perform the pull out test on 100 kn universal testing machine using pull out test attachment at 28 days age. The pull off test as a means of projecting the compressive strength of concrete and other materials involves bonding a circular steel disk to the surface by means of an epoxy resin adhesive.

5 1 for a given concrete and a given test apparatus pullout strengths can be related to compressive strength test results. A controlled tensile force is then applied to the disk and as the strength of the bond becomes greater than that of the material under stress it will. It is equally put under testing to identify its numerous specific uses. The lok test system is used to obtain a reliable estimate of the in place strength of concrete in newly cast structures in accordance with the pullout test method described in astm c900 bs 1881 207 or en 12504 3.

Capo test cut and pull out test lok test. This video shows a laboratory experiment for a pullout test on a reinforced concrete. We would like to show you a description here but the site won t allow us. Maybe you are not too familiar with chemical analysis.

The main test parameters of this investigation include embedment length surface type of reinforcing bars and bar. After 48 72 hours of rebar planting the tension meter jack can be used to carry out the drawing test of the reinforced bar. Steel bar reinforcement is not an exception. Record observations in the table as given below.

Note the load at 0 125 mm slip and at bond failure. To evaluate the bond behavior between the reinforcing bar and surrounding concrete a total of six group pullout specimens with plain steel bars and two group specimens with deformed steel bars serving as a reference are experimentally investigated and presented in this study.
