“…The effective immobilization of cesium in Portland cement-based matrices is well known to be challenging, and so the availability of a cementing system that can restrict its movement is highly desirable. There have been important recent investigations of the potential for compatibility of AAM matrices with complex waste streams containing multiple radioisotopes [265,266], with oily wastes [267,268], with ion exchange media [269,270], and with graphitic or metallic wastes [271][272][273]. AAM matrices have also been demonstrated to show generally good stability under irradiation [274][275][276], and a hydrogen radiolytic yield that depends on water content and pore structure [274].…”

The development of low-carbon binders has been recognized as a means of reducing the carbon footprint of the Portland cement industry, in response to growing global concerns over CO2 emissions from the construction sector. This paper reviews recent progress in the three most attractive low-carbon binders: alkali-activated, carbonate, and belite-ye'elimite-based binders. Alkali-activated binders/materials were reviewed at the past two ICCC congresses, so this paper focuses on some key developments of alkali-activated binders/materials since the last keynote paper was published in 2015. Recent progress on carbonate and belite-ye'elimite-based binders are also reviewed and discussed, as they are attracting more and more attention as essential alternative low-carbon cementitious materials. These classes of binders have a clear role to play in providing a sustainable future for global construction, as part of the available toolkit of cements.
