Ultrafine particles of supplementary cementations material relating to microheterogeneous systems are characterized by high values of specific interfacial area and “excess surface energy” and improved thermal stability of cement-based composites due to its high reactivity and particle packing effect.enelevated temperaturenanomodificationrapid hardening concreteultrafine supplementary materialsuperplasticizercompressive strengthConference Abstract143-144
