A new smart concrete aggregate design as a candidate for applications in structural health monitoring (SHM) of critical elements civil infrastructure is proposed. The cement-based stress/strain sensor was developed by utilizing the sensing properties magnetic microwire embedded composite (MMCC). This contact-less type that measures variations resulting from stress variations. Sensors made these materials can be designed to satisfy specific demand an economic way monitor health. For this...
This paper deals with the study of damage produced during freeze-thaw (F-T) cycles using two non-destructive measurement approaches-the first approach devoted to continuous monitoring embedded sensors cycles, and second one, performing ultrasonic imaging before after cycles. Both methodologies have been tested in different types concrete specimens, without air-entraining agents. Using approach, size distribution pores were estimated a thermoporometrical model measurements temperature...
A new versatile and geometrically reconfigurable ultrasonic tomography system (UTS) has been designed to inspect obtain information about the internal structure inner damage of columns in heritage buildings. This nondestructive is considered innovative because it aims overcome common limitations existing systems. Tomographic inspections are typically carried out manually thus limited small portions construction elements. The proposed UTS allows automatization inspection generation numerous...
A new free-form XR Kohler concentrator is presented that combines high geometric concentration, acceptance angle and irradiance uniformity on the solar cell. This achieved by modifying optical surfaces to produce integration. Although (that is, ones including integration) behave optically quite different from do not integrate, but macroscopic point of view they are very similar them. means can be manufactured with same techniques (typically plastic injection molding or glass molding) their...
A new design method of free-form Kohler integrator array optics is presented. Only few solutions to the problem are known, which apply for specific and simple source targets (for instance, flat lenslet arrays when target squares located at infinity). The presented here find more general resulting formed by two optical surfaces (which can be either reflective refractive). contour curves units also obtained from design. Two types Kholer integrators will defined, depending if they integrate...
This study explores the feasibility of using transmission tomographic images based on attenuation measures in to detect and estimate most common materials that are embedded concrete, reinforcements natural artificial voids. A limited set concrete specimens have been made which cylindrical objects such as bars/tubes steel, PVC aluminium analyse effect size material. The methodology scope this is presented numerical simulations carried out optimize emitter-receiver configuration understand...
<ns4:p><ns4:bold>Background:</ns4:bold><ns4:bold> </ns4:bold>The conservation of the built masonry heritage requires a comprehensive understanding its geometrical, structural, and material characteristics. Non-destructive techniques are preferred approach to survey historical buildings, given cultural value their fabric. However, currently available typically operated manually, consuming much time at operational processing level thus hindering use for on-site inspection...
