Description This paper deals with investigation of nanomodified Rapid hardening concretes with ultrafine mineral additives, polycarboxylate type superplasticizer at elevated temperature. 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.
