Probe penetration test

The mechanical averaging device consists of two triangular plates. How to cite this article. A major requirement of geotechnical engineering is an understanding of the soil and rock profile below a proposed development. Although efforts are continuing to improve non-destructive testing methods and the tests themselves are not difficult to perform, test data are not always easy to interpret because concrete is a most complex material. Link to Active This link will always route to the current Active version of the standard. The penetration of steel pin creates conical facture and a small hole indentation on the surface of the concrete.

Windsor Probe

As a result of the above-mentioned factors, a greater number of tests is necessary to detect significant variations in the concrete strength when comparing, for example, the probe penetration test with the rebound hammer test. One of the probe penetration tests reported in the literature is that proposed by Al-Manaseer and Nasser, [11], the test relies on a spring-loaded hammer similar to the one used in the rebound hammer test. This is a simple commun The system features an electronic measuring device for accuracy and efficiency. Thus, the possibility of using a non-destructive test was considered.

CBD Non-Destructive Testing of Concrete - NRC-IRC

Using the values for the slope and intercept from the correlation graph for the combined data, the correction function, Equation 3, could now be fully defined: This relationship depends on the strength of the aggregates. The shape of aggregates and nature of equipment influences the scatter of individual probe reading. A depth gauge measures the exposed lengths of the individual probes. However, a few anomalies did exist. This variability results from factors associated with errors caused by both the operator and the equipment due to the heterogeneous character of concrete.

The regression statistics showed that the linear model fits the data well, albeit with a relatively large standard error in y. Such trend was expected once the shotcrete at the entrance of the tunnel is older than that projected onto the final stretch of the tunnel. The papers written by these authors provided a description of the statistical method used and hence it was easy to adopt and change the method as necessary. His interests are the interactions between the various soil states and how these relate to strength and stability. Measure the exposed probe lengths and average the three results.
