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.

Flash Point and Fire Point Tests of Bitumen

Flash Point and Fire Point Tests of Bitumen

Flash point of bitumen is the temperature at which, its vapour will ignite temporarily during heating when a small flame is brought into contact with the vapour. The knowledge of this point is of interest mainly to the user, since the bitumen must not be heated to this point. The flash point tells the critical temperature at and above which suitable precautions are required to be taken to eliminate the danger of fire during heating. This temperature, however, is well below that at which the bitumen will burn. The latter temperature is called the fire point.

List of Tests for Bitumen as per Indian Standard

Overview Bitumen is the most important binding material for the construction of flexible pavement, which gives more strength than other materials used for flexible pavement. Therefore, a piece of thorough knowledge of the tests on bitumen is a must in the fields of civil engineering. Here, I am trying to give some names of tests …

field density test

Determination of field density of soil by Sand Replacement Method (IS 2720-28)

  Introduction Sand replacement test method is used to determine the field density or in-place density of earth embankments, road fills, sub-grade, sub-base or any of compacted material. This method serves as the base upon which one can accept the density of a compacted material to a specified magnitude or to a percentage of maximum unit dry density …
