Determination of gas porosity and gas permeability of hydraulic binders containing embedded radioactive waste Ingestion-build-59651 Ultimately1 Scope This International Standard describes the principles and methodologies of measuring both gas open porosity and permeability of hydraulic binder based matrices used for immobilization of radioactive waste. The measurements can be carried out by using different apparatus designed and constructed on the basis of a few recommended characteristics. The measurements can be performed on samples prepared in a laboratory or taken from industrial
