QUALITY CONTROL: A VERY RELEVANT QUESTION OF THE DAY

Human race is so quality conscious that they will not accept anything unless the quality ofcommodities and services is convincingly high. It is equally applicable to the field ofprofessional civil engineering as it is the field of petroleum and allied products.Firms and organization appoint quality engineers to examine test and assure the quality of commodities and services. Their timely intervention is unavoidable to find out the defects of products.He is the key personnel to say whether a product, service is ready for launching. As adecision maker in respect of quality, a quality engineer has much scope and power.

NDT ANALYSIS TECHNIQUES

Non-Destructive Testing (NDT) is a wide group of analysis techniques used in Science and Industries to evaluate the properties of a material component on system without any damage.

The term Non Destructive Examination (NDE), Non-Destructive Inspection (NDI) and Non-Destructive Evaluation (NDE) are also commonly used to describe this technology NDTdoes not permanently alter the article being inspected. It is a highly valuable technique thatwe can save money, efforts and time in product evaluation.

One of the major sectors providing job opportunity is engineering. Many companies in India and abroad look forward to the product from well known varieties well refined with extra qualifications in quality control (NDT).The QUALITY CONTROL ENGINEERING is a certification cum training program for engineers. In addition to quality control we are also offering training in NON DESTRUCTIVE

TESTING (NDT)

Nondestructive testing of concrete can be defined as the test method used to examine the

properties of concrete used in the actual structure. These test methods can also be said as in-

situ tests or in-place tests. Traditionally these tests are said to be as the non-destructive test

although some minor damage to the structure may be involved. An important feature of non-

destructive test is that the place where test is done can be used for re-testing. The use of non-

destructive tests has increased the safety level of construction and also helps in improving the

scheduling of construction. All this increases the speed of construction besides keeping the

economy of construction in considerable limits.

Definition:

These tests can be categorized in two parts:

1. Tests used to determine the strength of concrete

2. Tests used to determine the other characteristics of concrete like voids, cracks etc,

Nondestructive tests are the representation of relation between the property of structure which

is being tested and the strength of test specimen. These tests are usually done in case of

disputes between the parties which are involved in construction of any type of structure. Clients

usually ask to conduct the test of strength of concrete which is being used in the structure.

The most common tests which are usually conducted are:

Rebound Hammer Test

It is one of the oldest nondestructive test. This test is widely used because of its economical

procedure

Penetration Resistance Test

In this test resistance to the penetration of steel rod in the concrete is used as the strength

value

Ultrasonic Pulse Velocity Test

This test has automatic program apparatus. Apparatus is just placed on specimen. The waves

pass through the specimen. Time taken by waves to reach from one end of specimen to other

is considered to be the strength of specimen. Less the time taken, weaker will be the specimen

and vice versa)

Pull out Test

This test measure the strength of specimen by means of special tension jacks that are usually

used to be inserted in test specimen
