The research described in this paper is dedicated to the use of continuous fibers as reinforcement for additive manufacturing, particularly using Shotcrete. Composites and particular fiber reinforced polymers (FRP) are increasingly present concrete reinforcement. Their corrosion resistance, high tensile strength, low weight, flexibility offer an interesting alternative conventional steel reinfo...

Relentless cost declines in solar photovoltaic (PV) modules have radically reduced system costs, but the result is that racking costs become more important. In this study a new open source method using earth and shotcrete-based ground mounts investigated two geographic regions: (1) Boa Vista, Brazil, where PV rows an optimized shallow tilt angle can be close-packed (2) Kingston, Canada, racks m...

Pumice quarried by LAVA MINING AND QUARRYING SA from Yali Island, Dodecanese, is used in domestic and foreign markets mainly as concrete lightweight aggregate, masonry unit constituents, road substrate, loose soil stabilization. It a porous natural volcanic rock with low density, thermal noise transmission, the highest strength among all or artificial materials of mineral origin. Nowadays, pumi...

nowadays, distinctive methods are used in evaluation of the criteria in order to making decision. among them the analytic hierarchy process (ahp) is one of the most efficient. due to the seismicity of the vast majority part of the country and also the existence of the large number of the unreinforced masonry buildings, the application of the ahp method in order to reach to the best alternative ...
