Pozzolanic cements are produced by grinding together Portland cement clinker and a pozzolan, or by mixing together a hydrated lime and a pozzolan. Pozzolanic cements are particularly suitable for immobilisation since the permeability of the concrete is greatly reduced by the continuous filling of the pore volume during the hydration reaction.
