| Push Pull Testing For Building Industry With Calibrated Measuring Instruments. Mechanical Load Testing Procedures For On Site Proof To Testing Demands. |

Push pull testing is normally performed to measure the strength of the material bonding is between a typical bolt and concrete. Push pull testing procedures are performed according to BS5080 Part 1 demands. Even though materials used for bonding may be different, it is important to note that testing for bonding strength is an universal principle. Push pull testing and tensile strength testing is normally performed because many factors which impinge upon proper bonding of the fixings. The greatest concern is that some of these factors may not be noticed especially when inspection is only carried out visually. Among these are damage caused to the bonding material resulting from low temperature, frost, or when water infiltrates into the joint. Another reason for poor surface bonding strength is as a result of smooth side walls. The entire integrity of the whole structure lose in strength so as to loose the integral strength of the structure due to the essential bonding materials fail. Ultimately, this may result in construction failures leading to disastrous consequences. Push pull testing enables early diagnosis of such faults and defects. Because of this, constructors are able to rectify faults. Early fault finding mitigates future problems. It also helps to add to the assurance of any structure's integrity. Push pull testing is conducted either on large scale or a smaller intensive scale. Testing always entails duplication of the design maximum stress levels anticipated in construction as required by the standards of the industry. This is not destructive testing so the maximum loads applied as well as the sample scale of the tests are determined by the on-site engineers. Push Pull Testing is a sampling as a quality assurance measure. Should problems be found then the Pull Out Testing can be used to quickly find out the extent of any problem. Quicker Pull out testing (larger sample testing) may be applied under the circumstances where the costs of the large scale is far reaching and problems have been detected. Pull Out Tests can quickly test more fixings and will only show the pass or fail of maximum loads being tested. The test procedure are the same as Push Pull Tests but only the pass or failure is recorded. While the Push Pull Tests can find problems the quicker Pull Out Tests will find out the extent of such problems. |
