Rebound Hammer Testing Concrete|Surface Hardness Test|Rebound Hammer Test

Rebound Hammer Testing Concrete|Surface Hardness Test|Rebound Hammer Test | Non Destructive Testing | Scoop.it
Whether it is a Surface hardness test using a rebound hammer or testing concrete using rebound hammer. Sigma has many years of experience in both the testing.
ndttestingindia's insight:

Rebound hammer test is conducted to find out the compressive strength of concrete by using rebound hammer. The rebound of an elastic mass depends upon the hardness of the surface when it strikes. When the plunger of rebound hammer is pressed against the surface of the concrete, the pring controlled mass rebounds and the extent of such a rebound depends upon the surface hardness of the concrete.SIGMA TEST & RESEARCH CENTER performs Rebound Hammer Testing.

Core Cutting Test For Soil Compaction,Concrete|Core Cutter Test|Core Cutting Testing

Core Cutting Test For Soil Compaction,Concrete|Core Cutter Test|Core Cutting Testing | Non Destructive Testing | Scoop.it
Sigma holds a degree in Core cutting test for soil concrete compaction. Sigma Core cutting testing experts are perfectly trained and gives their client fully satisfaction by their testing.
ndttestingindia's insight:

The strength of concrete measured by tests of cores is affected by the amount and distribution of moisture in the specimen at the time of test. There is no standard procedure to condition a specimen that will ensure that, at the time of test, it will be in the identical moisture condition as concrete in the structure.

Ndt Ultrasonic Testing Materials,Welds|Ultrasonic Inspection | Non Destructive Testing | Scoop.it
Ndt Ultrasonic Testing of Materials and Welds, Sigma covers every kind of Ultrasonic Inspection which will result to the honest report of Ultrasonic test.
ndttestingindia's insight:

Sigma Test and Research Centre offer the services for testing concrete where the velocity of ultrasonic pulses is measured and identification of cracks, voids, strength and elasticity is checked determining the areas which can provide the basis for recognizing the defects. The pulse velocity in a material depends on its density and its elastic properties which in turn are related to the quality and the compressive strength of the concrete.

Rebound Hammer Testing Concrete|Surface Hardness Test|Rebound Hammer Test | Non Destructive Testing | Scoop.it
Whether it is a Surface hardness test using a rebound hammer or testing concrete using rebound hammer. Sigma has many years of experience in both the testing.
ndttestingindia's insight:

The rebound hammer can provide an estimate of compressive strength of the concrete according to IS:13311 (Part 2). It is a non destructive testing device, which is used on finished concrete structures, such as precast concrete septic tanks. However strict
procedures must be followed if the test results are to have any validity.

Ndt Visual Testing|Visual Inspection Welds|Visual Testing Ndt | Non Destructive Testing | Scoop.it
Ndt Visual Testing has been done by many Visual Inspection Ndt methods. Sigma deals in visual testing of welds also.
ndttestingindia's insight:


Visual Inspection means the inspection of equipment and structures using a combination of human senses such as vision, hearing, touch and smell. Visual Inspection is sometimes carried out in conjunction with devices such as a low power magnifying glass, boroscopes, fiberscopes, digital video borescopes, camera systems and robotic crawler systems.

Ndt Ultrasonic Testing of Materials and Welds, Sigma covers every kind of Ultrasonic Inspection which will result to the honest report of Ultrasonic test.
ndttestingindia's insight:

Ultrasonic flaw detection is basically a comparative technique. Using appropriate reference standards along with knowledge of sound wave propagation and generally accepted test procedures, a trained operator identifies specific echo patterns corresponding to the echo response from good parts and from representative flaws

Destructive,Nondestructive Testing Concrete|Non Destructive Testing,Inspection,Lab,Companies,Services | Non Destructive Testing | Scoop.it
Non Destructive Testing of Concrete is done here in Non Destructive Testing Lab. Sigma Test cover inspection and gives services of Nondestructive Testing.
ndttestingindia's insight:

Dye penetration is a non-destructive method which is used to detect surface breaking discontinuities in metals, plastics and ceramics. The test is performed by cleaning the test surface thoroughly and then applying the penetrant followed by the application of developer. The developer assists to draw penetrant out from the surface breaking the discontinuities.

Hardness Testing Portable,Rockwell Superficial,Brinell,Vickers,Concrete,Mohs-Hardness Testing

Hardness Testing Portable,Rockwell Superficial,Brinell,Vickers,Concrete,Mohs-Hardness Testing | Non Destructive Testing | Scoop.it
Different Hardness testing methods are Portable,Rockwell Superficial,Brinell,Vickers,Concrete,Mohs. Sigma covers all these Hardness testing with honest and accurate results.
ndttestingindia's insight:

Hardness is a material's resistance to penetration. In general, an indenter is pressed into the surface of the material to be tested under a specific load for a definite time interval, and a measurement is made of the size or depth of the indentation.

Hardness properties include such varied attributes as resistance to abrasives, resistance to plastic deformation, high modulus of elasticity, high yield point, high strength, absence of elastic damping, brittleness or lack of ductility.

Ndt Test For Concret

Ndt Test For Concret | Non Destructive Testing | Scoop.it

Nondestructive techniques are the means by which materials and structures may be inspected without disruption or impairment of serviceability. The science of nondestructive testing incorporates all the technology for detection and measurement of significant properties, including discontinuities, in items ranging from research specimen to finished hardware and products.

Nondestructive testing has become a progressively more fundamental factor in the effective conduct of research, development, design and manufacturing programs. However, the information required for appreciating the broad scope of nondestructive testing is widely scattered in a multitude of publications and reports.

The National Materials Advisory Board (NMAB) Ad Hoc Committee on Nondestructive Evaluation adopted a system that classified methods into six major categories: visual, penetrating radiation, magnetic-electrical, mechanical vibration, thermal and chemical- electrochemical.
