This work shows the results obtained by replacing Type I Portland®, by cementitious geopolymers materials, derived from minerals, in concrete mixtures. Synthesis of both geopolymers through alkaline activation of two alluminosilicates: Bentonite and Pumice with sodium silicate (N...

This paper presents results of a research project related to the development of alkali-activated geopolymers, synthesized from alumina-silicate minerals (fly ash and pumice) which are added to concrete. Alkali sources used in geopolymer synthesis were sodium hydroxide and sodium ...

The title molecular complex, C9H7NOC7H5NO4, owes its formation to an intermolecular hydrogen bond between the OH and NO groups, with an OO distance of 2.514 (2) A . The dihedral angle between the planes of the isoquinoline N-oxide and nitrobenzoic acid rings of the complex is 4...
