Advanced manufacturing and new energy systems are presenting a wide variety of challenges for nondestructive testing and evaluation (NDT/NDE). This paper discusses the state of the art, needs and opportunities for NDE to provide reliable, effective and economic inspection and monitoring for energy systems. It introduces issues of materials, defects and allowables, the evolution of advanced NDT ...

The concrete industry is under increasing pressure to reduce greenhouse gas emissions. An immediate solution minimize the amount of Portland cement used by partially substituting other supplementary cementitious materials. This article presents results an experimental campaign on influence replacing with both calcined and uncalcined diatomites from filtration beer wine in production elements ma...

Several million cubic meters of concrete are pumped daily, as this technique permits fast placement. Fundamental research has been performed and practical guidelines have developed to increase the knowledge behavior in pipes. However, pumping process not fully understood. This paper gives an overview current pumping. At first, known physics governing flow pipes introduced. A series experimental...

Earth-moist concrete mixes are the starting substance for the mass production of concrete products like pipes, slabs, pavement stones and curb stones. The working properties of earth-moist concrete (EMC), caused by its dry consistency, are advantageous. So, in comparison to normal-weight concrete, the consistency of EMC allows for direct stripping of concrete products after filling and vibratin...
