The stone industry is one of the most essential industries in the Alpine region. This research aims to evaluate the possibility of reusing secondary waste materials produced by the quarry sector as aggregates in Ultra-High-Performance Fiber Reinforced Concrete (UHPFRC). The secondary materials involved were Diabase Sand, Diabase Powder, Dolomite Sand and Dolomite Gravel from crushed stone quarries from the regions of Carinthia and Tyrol in Austria, as well as Limestone Powder from the preparation and production of...

Models for resource and environmental management should be as specific as possible, but complex, regional environments are highly variable and not readily compared, as would be desired for decision support. This paper presents selected tools to improve the transparency and quantitative character of modelling procedures and databases are presented. These methods are largely related to existing procedures for regional relative risk ranking, but also include system structural analysis and risk classification. Several...

The aim of this work is the optimization of sinter-crystallization regime of a glassceramic from a municipal solid waste incineratior (MSWI) bottom ash. The parent waste was melted at 1400oC, milled below 75 $\mu$m and the obtained glass powders were pressed at 100 MPa. The optimal temperature for sinter-crystallization was estimated by DTA, dilatometry and XRD. Subsequently, the degrees of sintering, obtained at different heating rates (between 2 and 40oC/min) and 1 h step at 950oC were estimated by the linear sh...
