Magnetic Crack Detector as NDT Test of Concrete

Magnetic Crack Detector as NDT Test of Concrete

Electroflux Magnetic Crack Detector equipment is designed for non-destructive testing (NDT Test) of ferrous iron and steel parts. Electroflux equipment will locate cracks and other defects in parts which can be magnetized. When properly used, Electroflux will locate such defects as fatigue cracks, heat cracks, grinding checks, forgings laps, shrinks and tears in castings, improper welds and inherent defects in metal such as seams and inclusions as well as cracks due to over stressing of parts. These defects may not be visible to the naked eye but can be located rapidly and accurately with this equipment.

Compaction Factor Test

Compacting Factor Test to Determine it’s Workability

The compacting factor is defined as the ratio of the weight of partially compacted concrete to the weight of fully compacted concrete. It shall be stated to the nearest second decimal place. Compacting factor test is adopted to determine the workability of concrete where the nominal size of the aggregate does not exceed 40 mm. It is based on the definition, that workability is that property of concrete, which determines the amount of work required to produce full compaction. The test consists essentially of applying a standard amount of work to a standard quantity of concrete and measuring the resulting compaction.
