High performance fiber reinforced concretes (UHPFRC) have a considerable environmental impact because they contain high quantities of cement, the production of which is associated with significant CO2 emissions. The present paper presents the results of the MATERSOS Project funded by the Emilia Romagna Region, in relation to the development of UHPFRC containing secondary raw materials. In a first phase of the project, various waste materials available at regional level were analyzed in order to identify those most suited for being used as secondary raw materials in concrete. The most promising materials, based on chemical and mineralogical analyses, were used to develop high-strength concrete mixtures. The present paper presents the developed concrete admixtures and their main mechanical characteristics
I calcestruzzi fibrorinforzati ad alte o altissime prestazioni (Ultra High Performance Fiber Reinforced Concretes – UHPFRC) sono caratterizzati da un notevole impatto ambientale perché contengono notevoli quantità di cemento, la cui produzione è associata a significative emissioni di CO2. La presente memoria presenta i risultati ottenuti nell’ambito del progetto di ricerca MATERSOS finanziato dalla Regione Emilia Romagna, in relazione allo sviluppo di UHPFRC contenenti materie prime seconde. In una prima fase del progetto sono stati analizzati gli scarti ed i rifiuti disponibili a livello regionale che potessero prestarsi a tale utilizzo. Successivamente i materiali risultati più promettenti sulla base di analisi chimiche e mineralogiche, sono stati impiegati per sviluppare miscele di calcestruzzo ad altissima resistenza. La memoria presenta le miscele sviluppate e le principali caratteristiche meccaniche dei materiali ottenuti.

High performance fiber reinforced concretes (UHPFRC) have a considerable environmental impact because they contain high quantities of cement, the production of which is associated with significant CO2 emissions. The present paper presents the results of the MATERSOS Project funded by the Emilia Romagna Region, in relation to the development of UHPFRC containing secondary raw materials. In a first phase of the project, various waste materials available at regional level were analyzed in order to identify those most suited for being used as secondary raw materials in concrete. The most promising materials, based on chemical and mineralogical analyses, were used to develop high-strength concrete mixtures.
