AbstractCement board reinforced with basalt fibers were prepared by using polymer compounds, 5% of water-based of isocyanate-polyester polyol prepolymer blend was used as a fixed percentage, and the rates of basalt fiber used were 5%, 7.5%, 10%, 12.5%, an... see more

La resistencia a las heladas es una de las características más importantes que describen un elemento estructural de hormigón. En condiciones de procesos de congelación/descongelación frecuentes y repetidos, la estructura se debilita significativamente. Lo... see more

Thermophysical, physical-mechanical and acoustic characteristics of a rough continuous basalt fiber under the influence of operating factors and a corrosive environment are studied. It is shown that the production of protective materials with high thermop... see more

ResumenEn el estudio se utilizó un método de flexión de tres puntos para determinar la tenacidad de la fractura de los hormigones con fibras de basalto. Las propiedades de fractura y el comportamiento posterior al agrietamiento del hormigón, se analizaron... see more

The paper presents the history, current state and possible future protection, and development of the open-cast mining heritage. An example is the abandoned basalt quarry in Strzegom known under official name ”The Zólkiewka Quarry” although local community... see more

Lava flows are a common hazard at basaltic to intermediate volcanoes in general and have posed a significant threat to La Reunion Island specifically over the past centuries. In sustained flow units, the efficiency of lava transport away from the vent is ... see more

The basaltic lava flows located in the southeast of Payenia Volcanic Province, Argentina, show lengths between 40 and 181 km. These flows have transversal sections characterized by external vesicular crusts that surround a massive core hosting vesiculated... see more
