Probe penetration test

Your email address will not be published. Cone probes are used for gels or viscous materials, needle probes for silicone pharmaceutical stoppers, and broader probes for penetrometers as used in cements and concretes. Penetration testing is very similar to compression testing with one key difference: However, no such relationship was apparent when analysing the data. Materials for Repair of the Concrete Structure. But it is preferable to express the coefficient of variation in terms of depth of penetration as the fundamental relation is between concrete strength and penetration depth. Penetration resistance values from the two tests are often taken as equivalent for design purposes, as the same drive energy is used in both.

IMPACT AND PENETRATION TESTS OF PORTLAND CEMENT CONCRETE

Table 4 summarises the range of COV values for all strata at each site and gives the average. Dynamic probing involves driving a steel cone vertically into the ground using a sliding hammer and recording the number of blows for each mm of penetration. Rebound Hammer Test Procedure. Finally, the probe penetration test was considered. The Windsor Probe test has been approved by federal, state and municipal agencies as well as a number of foreign countries. This is an economical alternative for many concrete test environments. It is used to drive pointed hardened steel pin of 3.

Non-destructive tests used to assess the structure Several non-destructive tests are applicable in the evaluation of concrete structures, [1,2], including the pullout test, the probe penetration test, the maturity method, the rebound hammer test, ultrasound, and impact-echo. An extractor is supplied to facilitate probe removal after the test. For sites where probing was over a large area, N and N 30SB profiles were separated into subsites with similar soil profiles based on borehole logs. A comparison was then made between the relative density assigned by N values and N 30SB values. The Windsor HP results correlate well with the concrete strength determinations obtained by conventional means.

The parameter that characterises the method is called the penetration index and is represented by the length of the part of probe that has not penetrated the concrete. To reduce possible errors caused by the operator, all tests were performed by the same, properly qualified individual. The probe has a diameter of 0. In light of the observations made during the tests and the results presented here, the following conclusions were obtained. Due to the variation in the thickness of the concrete plates resulting from the process of producing the same in the tunnel, the height of the core samples ranged from
