Hydrogen defects in feldspars: defect properties and implications for water solubility in feldspar

Behrens, Harald (Berlin ; Heidelberg : Springer, 2021)

Hydrogen defects can strongly affect mechanical and chemical properties of feldspars. To get insight into the behavior of such defects, alkali feldspar and plagioclase of igneous origin were studied combining IR spectroscopy ...
Microstructure and mechanical, physical and structural properties of sustainable lightweight metakaolin-based geopolymer cements and mortars employing rice husk

Riyap, H.I.; Bewa, C.N.; Banenzoué, C.; Tchakouté, H.K.; Rüscher, C.H.; Kamseu, E.; Bignozzi, M.C.; Leonelli, C. (Abingdon : Taylor and Francis Ltd., 2019)

This work focuses on an in-depth investigation of the formation of pores in the structure of lightweight geopolymer cements and mortars using rice husk as a foaming agent. The hardener used in this study was sodium waterglass. ...
Water resistance and thermal behavior of metakaolin-phosphate-based geopolymer cements

Nobouassia Bewa, Christelle; Tchakouté, Hervé K.; Fotio, Daniel; Rüscher, Claus H.; Kamseu, Elie; Leonelli, Cristina (Abingdon : Taylor and Francis Ltd., 2018)

The main target of this work was to investigate the thermal behavior and water resistance of geopolymer cement made from metakaolin as an aluminosilicate source using phosphoric acid solution (10 M) as a hardener. The ...
