Abstract

Architectural structures including an inorganic material carrier including cement and particles or fibers of a glass including a plurality of Cu¹⁺ ions. In aspects, the glass may have a glass phase and a cuprite phase. In aspects, the glasses may include a plurality of Cu¹⁺ ions, a degradable phase including B₂O₃, P₂O₅ and K₂O and a durable phase including SiO₂. In other aspects, the glass can have a plurality of Cu¹⁺ ions disposed on the surface of the glass and in the glass network and/or the glass matrix. The glasses and articles disclosed herein can exhibit a 2 log reduction or greater in a concentration of at least one of Staphylococcus aureus, Enterobacter aerogenes, Pseudomonas aeruginosa bacteria, Methicillin Resistant Staphylococcus aureus, and E. coli, under the EPA Test Method for Efficacy of Copper Alloy as a Sanitizer testing condition and under Modified JIS Z 2801 for Bacteria testing conditions.
