During the last decades, the concrete industry has been widely developing in many ways such as the methods of pouring concrete in order to achieve high quality concrete and low cost. Some new concretes have been produced which is completely defer from the conventional concrete in the method of mixing, pouring and no need for the normal compaction methods that require more labors, tools and cost more. This paper presents two special types of concrete; Two-Stage Concrete and Rock Filled Concrete and presents the advantages and special requirement ....etc

Underwater Welding

Welding is an unavoidable process of modern engineering ? civil, electrical, mechanical, automobiles, marine aeronautical ? in all branches. It is used in fabrications and erections in infrastructures and installations. It joins metals or thermoplastics. Forming a pool of molten mass ? the weld puddle ? and allowing it to cool to become a strong joint is the basis of the process of welding. For repairing to be carried out underwater, there is a separate process. That is called un ....etc

Abstract

Acoustic emission testing technique is a dynamic testing technology. In this paper, the relationship between the cumulative energy of acoustic emission and lower cycle reversal loads is studied based on results of the experiments on underwater concrete columns, and waveform acoustic emission signal of different destruction states is picked up. Spectrum analysis is carried out, the results of which are compared with those of parametric analysis. The comparison shows that the waveform ac ....etc
