Global warming is one of the main problems that facing modern civilization. As buildings consume 40% total energy, heating in cities a primary concern. Therefore, it seeks to improve sustainable construction materials with better thermal and reflective properties, reducing consumption heat islands. In this work, mineral engineered feldspars have been used as partial substitution white cement, w...

Abstract. The success of luminescence dating as a chronological tool in Quaternary science builds upon innovative methodological approaches, providing new insights into past landscapes. Infrared radiofluorescence (IR-RF) on K-feldspar is such an method that was already introduced two decades ago. IR-RF promises considerable extended temporal range and simple measurement protocol, with more appl...

Biotechnological treatment of non-metallics is based on bacterial leaching raw material and dissolution Fe. Bacterial iron ability dependent various physicochemical factors as temperature, acidity solutions, redox potential, rapidity water circulation presence organic sources. The Fe content in the quartz sands feldspar samples by biological decreased much 60% subsequent using electromagnetic s...
