Ultra-high performance concrete (UHPC) is commonly defined as a cementitious material, reinforced by fiber, which has compressive and sustained post-cracking tensile strength of more than 21.7 ksi (150 MPa) and 0.72 ksi (5 MPa), respectively. The outstanding mechanical behavior of UHPC is owed to its particular mixture.

Applying thin ultra-high-performance concrete overlays over normal concrete bridge decks can improve bridge deck durability by increasing the

concrete with very high durability and very low permeability is consid-ered to have high-performance properties. Bickley and Fung (2001) demonstrated that 40 MPa (6,000 psi) high-performance concrete for bridges could be eco-Fig. 17-1. High-performance concrete is often nomically made while used in bridges (left) and tall buildings (right

ExoLeaf® Ultra High Performance Fibre Reinforced Concrete. The redevelopment of 9-11 Elmer Approach in Southend-on-Sea required two additional floors to be added to the existing 10-storey building as part of its transformation into a 108 room hotel. To facilitate the load of the new levels, columns throughout the building required strengthening.

Concrete homes are known for their durability and cost-saving features. In today's construction revolution, there is great demand to build high-performance homes. With ICF construction, homeowners can design a concrete home to look just like a wood-frame house, but they garner many other added benefits by choosing to build with concrete.
