Present paper objective is to assess the seismic hazard and seismic risk and provide an analyses of earthquake scenario for the transboundary area of Ungheni town in Republic of Moldova and Ungheni-Prut in Romania. For the present study as design seismic action (earthquake scenario) was selected the Vrancea earthquake with 475 years return period and magnitude Mw = 7.9. At first it was analyzed specified earthquake scenario using special macro seismic attenuation equation. This allowed the obtaining of probable di...

As natural resources are rapidly depleting and the demand of cement based products in construction industry is continuously increasing, there is a pressing need for finding alternatives without large penalties in terms of mechanical properties. Another issue to be resolved is related to current design guidelines developed for traditional cement based materials (e.g. mortar and concrete). Zeolites, either natural or synthetic, are crystalline alumina silicates with pozzolanic activity in cement based materials that...
