Resumo

This chapter is an overview of the knowledge of ultrahigh performance concrete (UHPC) manufactured using inert residues as replacement of the different size of its composition. The feasibility of using different types of waste as supplemental cementitious materials is also described. First, the materials and composition of the UHPC are analyzed. The different types of waste used in the different studies consulted are described later. The manufacturing process and curing of the UHPC are also reviewed. Likewise, an analysis of the values corresponding to the most relevant mechanical properties of the UHPC obtained in the different studies is conducted. Finally, the durability of this type of concrete is analyzed. Permeability, porosity, carbonation, chloride ion penetration, the free thaw cycles resistance, and the fire resistance have been assessed.
