Idratazione del cemento - Wikipedia

Si evince che a parità di rapporto acqua/cemento la resistenza della pasta di cemento, e quindi del calcestruzzo, aumenta con l'aumentare del grado di idratazione essendo maggiore la percentuale di cemento idratato (e pertanto il tenore dei silicati idrati di calcio) Il grado di idratazione é influenzato dalla temperatura
