Structure and density of the parent glasses and the hydrated gels (before and after aging). a Time-dependence of the number of bridging oxygen per Si atom (BO/Si) during the accelerated aging of the hydrated gels. b BO/(Si + B) molar ratio in the parent glasses and in the hydrated gels (before and after aging) as a function of the B2O3 molar fraction in the parent glass. c Density of the parent glasses and hydrated gels (before and after aging) as a function of the B2O3 molar fraction in the parent glass
