  • Refractories and Classification of Refractories –

    Ramming mixes consist essentially of ground refractory aggregates, with a semi-plastic bonding matrix which can be purchased ready-to-use or prepared by adding water in the mixer at the construction site. Ramming mixes are very similar to plastic refractories, but ramming mixes supply a denser, stronger refractory body than plastic refractories.
