AbstractThe number of products that have to be inspected in pre-service and/or in service is increasing. Not only inspection for flaws are required increasingly, using the ordinary non-destructive testing, but also inspection of material characteristics, such as material strength evaluation and/or damage detection. For such inspection, X-ray diffraction has great possibilities as one of the most promising techniques, because it is (a) noncontact, (b) very sensitive to changes in parameters of the crystalline structure, and (c) suitable for surface observation.In this paper, three topics are introduced which will be useful in the field of material strength evaluation and damage detection using X-ray diffraction.

This paper outlines the standardisation process for the XRPD method that is currently being considered by a Working Group (WG10) of Technical Committee 138 "Non-destructive Testing" of the European Committee for Standardisation CEN. Several Standard Documents are on the verge of being released. These documents concern the general principles of (X-ray) diffraction, its terminology, and the basic procedures applied. Another document concerns the instruments used and it offers procedures to characterise and control the performance of an X-ray diffractometer properly. It is intended to issue Standard Documents on specific methods, e.g. determination of residual stresses. In fact work is in progress on this subject. The Standard Documents can be used by industry, government organisations, and research centres with activities related to safety, health and the environment, as well as for educational purposes.

Today, only a very small portion of plastic waste is recycled, while huge quantities remain untreated and are becoming increasingly worrying. The search for other alternatives is still an urgent necessity so that these wastes can be reduced to the maximum; their valorization may be the best solution. This study concerns a new technique for the valorization of polyethylene terephthalate (PET) plastic bottle wastes, in order to design a composite material, i.e. siliceous sand-PET, which then gives a Waste Plastic Lightweight Aggregate “WPLA”. Our hope is to provide solutions to specific and general applications in the field of construction. Some observations are noted on the effects of this composite on destructive and non-destructive testing, such as the physical properties and mechanical behaviors of an industrial composite screed, by substituting 0, 25, 50, 75 and 100% by weight of natural aggregate by this composite. Scanning electron microscope (SEM), FT-IR and X-ray diffraction analyses were used to better understand the cement hydration products of the composite mortars. Some possible uses of this screed, or even of the composite itself, can subsequently be recommended. Encouraging results were obtained regarding the usage of this composite aggregate as an eco-material in the field of construction for sustainable development. In addition, it provides environmental-friendly and cost-effective solutions in using recycled materials for concrete construction applications.
