The test results regarding concrete uniformity by using the Schmidt rebound hammer is shown in Fig.2, taken from the port deck surface. The hammer readings are between 20 to 45 on the hammer scale, with an average of about 33 and a deviation of ± 6.9 which shows that the concrete quality on the deck surface is very non-uniform.

BASIC METHODS FOR NDT OF CONCRETE STRUCTURES

The following methods are commonly used for NDT of concrete structures. The typical applications of those methods are briefed. 1. Visual inspection of concrete structure is carried out before any intended non-destructive test. Visual inspections provides information on type of concrete damage, their possible causes and type of NDT test suitable for further investigation.

Nondestructive test (NDT) methods are used to determine hardened concrete properties and to evaluate the condition of concrete in deep foundations, bridges, buildings, pavements, dams and other concrete construction. For this report, nonde-structive testing is defined as testing that causes no structur-ally significant damage to concrete.

Introduction to Nondestructive Testing

What Is Nondestructive Testing? Nondestructive testing (NDT) is the process of inspecting, testing, or evaluating materials, components or assemblies for discontinuities, or differences in characteristics without destroying the serviceability of the part or system. In other words, when the inspection or test is completed the part can still be used.

Nondestructive Strength Testing| Concrete Construction ...

Q: Is there a way to determine the compressive strength of concrete in-place, without removing samples for laboratory testing? A: There are several nondestructive tests (NDT) that can be used to evaluate the strength of hardened concrete. Two of the most common NDT methods are the Schmidt rebound hammer and the Windsor probe, both of which measure the surface hardness of concrete as a quick ...

Non-Destructive Testing of Concrete and its Methods

Non-destructive testing of concrete is a method to obtain the compressive strength and other properties of concrete from the existing structures. This test provides immediate results and actual strength and properties of concrete structure.

Non-Destructive Evaluation of Concrete using Ultrasonic ...

The UPV and the compressive strength of concrete increase with age, but the growth rate varies with mixture proportion. A relationship curve is drawn between UPV and compressive strength for concrete having different w/c from 0.35 to 0.7. Key words:Compressive strength, concrete properties, non-destructive evaluation, testing concrete,

Non-Destructive Testing of Concrete

Non-Destructive Testing of Concrete The standard method of evaluating the quality of concrete in buildings or structures is to test specimens cast simultaneously for compressive, flexural and tensile strengths. The main disadvantages are that results are not obtained immediately; that concrete in specimens may differ from that in the actual
