Penetration resistance test penetration resistance test on concrete
It provides solutions to all problems pertaining to houses right from concept to completion. Nowadays concrete testing experts are using the NDT test like penetration resistance test to determine the relative strength of the concrete in the structure. It estimates the strength of concrete from the depth of penetration of a steel rod. In this method, the steel rod or steel probe is fire on the concrete surface by a sudden explosion. The penetration is inversely proportional to the compressive strength of concrete in the standard test condition.
However, the probe penetration does relate to some property of the concrete below the surface, and, within limits, it has been possible to develop empirical correlations between strength properties and the penetration of the probe. As the device looks like a firearm it may be necessary to obtain official approval for its use in some countries. The probes have a tip diameter of 6. Probes of 7.
