Methods for engineered cellular magmatic geotechnical fill and articles thereof are disclosed. For example, the magmatics may include one or more infiltration materials that are configured not to sinter when a foamed mass is formed. The infiltration materials may be enclosed in cells of the foamed mass and may be floating and/or fixed to the cell walls.

A glass composition includes: greater than or equal to 53 mol % and less than or equal to 70 mol % SiO.sub.2; greater than or equal to 9 mol % and less than or equal to 20 mol % Al.sub.2O.sub.3; greater than or equal to 10 mol % and less than or equal to 17.5 mol % B.sub.2O.sub.3; greater than or equal to 0 mol % Li.sub.2O; greater than or equal to 0 mol % Na.sub.2O; and greater than 0.1 mol % of a nucleating agent. The sum of Li.sub.2O and Na.sub.2O in the glass composition may be greater than or equal to 8 mol % and less than or equal to 30 mol %. The amount of Al.sub.2O.sub.3 minus the sum of R.sub.2O and RO in the glass composition may be greater than or equal to −3 mol %. The glass composition may be phase separable and may have an improved K.sub.Ic fracture toughness.

Porous glass nanoparticles according to an embodiment have a specific surface area of 250 m2/g to 800 m2/g, and a pore volume of 0.1 cm3/g to 1 cm3/g. Since the porous glass nanoparticles have a high specific surface area and pore volume, the porous glass nanoparticles may have improved agilities to remineralize the demineralized dentin and occlude dentinal tubules. In addition, by including the porous glass nanoparticles, a dentin adhesive composition with improved adhesive strength to the dentin surface may be provided.

A glass, glass ceramic, or ceramic bead is described, with an internal porous scaffold microstructure that is surrounded be an amorphous shield. The shield serves to protect the internal porous microstructure of the shield while increasing the overall strength of the porous microstructure and improve the flowability of the beads either by themselves or in devices such as biologically degradable putty that would be used in bone or soft tissue augmentation or regeneration. The open porosity present inside the bead will allow for enhanced degradability in-vivo as compared to solid particles or spheres and also promote the growth of tissues including but not limited to all types of bone, soft tissue, blood vessels and nerves.
