Abstract

A large region of glass formation was found in the system SrO-MgO-ZrO2-SiO2 and some properties have already been reported. Detailed studies have shown that glasses with only 40 wt% silica unusually durable in 1 M NaOH and also in model cement extract solutions. Glasses with higher silica contents are more easily attacked; zirconia and magnesia are the constituents giving the best durability. These results suggest that these glasses could be of interest for reinforcement of cement and concrete. (C) 2000 Elsevier Science Ltd. All rights reserved.
