Concrete is an indispensable construction material of modern age. The properties of concrete are greatly dependant on the constituents, workmanship, water-cement ratio, compaction, curing etc. Direct assessment of the strength of concrete is not possible because direct tests induces destructive stresses and causes failure of the structure. So the concrete strength is tested using standard specimens made with the same mix as that of the structure. But the test specimens can vary from the actual structure in properties due to difference in compac ....etc

Destructive Examination & Testing
Destructive Examination
 Destructive testing, as the name suggests, involves the physical destruction of the completed metal in order to evaluate its characteristics.
 Destructive testing perform in order to understand a specimen's structural performance or material behaviour under different loads. These tests are generally much easier to get information about any material, and are easier to interpret th ....etc

Abstract
Destructive and non-destructive methods have been used for the determination of micro-traces of antimony in high-purity silicon powder. The destructive method was based on sub-stoichiometric radio-activation analysis with solvent extraction using BPHA and cupferron as organic reagents. The antimony contents in high-purity silicon can be determined by the proposed method.
A new non-destructive method was developed for the detection of refrigerant leakage at an evaporator's inflow. Nitrogen and oxygen gas were suc ....etc

SYNOPSIS

Non- destructive estimation of particle size of finished products is essentially required to judge their suitability for intended applications. For this estimation, a ceramic heating element (SiC rod) of a heat Treatment furnace at 1400 Degree celcius has been chosen. The particle size has been estimated with the proposed method based on counting reflection spots in a back reflection X-Ray pattern. Calibration curve has been drawn on the basis of the data obtained by standard sieve me ....etc

ABSTRACT
Condition monitoring of components and plants are of great importance for safe and reliable operation and for increasing productivity of plants. The challenges towards the condition monitoring can be successfully met by employing non-destructive evaluation (NDE) techniques. Vibration monitoring techniques are applied for periodic / continuous assessment of machinery parts and plants. Acoustic emission technique is used for leak detection and for structural integrity monitoring applications. Inf ....etc

The study of micro cracks in concrete is very important to understand its behavior under loading and to improve this material. The direct observation in a scanning microscope is not a suitable method because the concrete is subject to drying shrinkage. Another indirect and non destructive method of observation by SEM is proposed. With this method using a single replica the micro cracks of concrete can be observed better than 0.5 µm. ....etc

INTRODUCTION
The successful operation of structures / components during their entire life requires the implementation of a dedicated programme for condition assessment through in-service inspection (ISI) of all critical components of the plants / structures. The condition assessment through ISI and life prediction approaches enable uninterrupted operation, avoidance of unplanned shutdowns and taking decision on repair, up-gradation, modernization and replacement of necessary components for extension ....etc
