Ultra High Performance Concrete (UHPC): 

Ultra High Performance Concrete (UHPC) Kelly Grahmann MEEN 3344 Texas A&M University - Kingsville

What is UHPC: 

What is UHPC It is also known as Reactive Powder Concrete (RPC) It is a high strength, ductile material formulated by combining portland cement, silica fume, quartz flour, fine silica sand, high-range water reducer, water, and steel or organic fibers

Comparing Properties: 

Comparing Properties Properties of UHPC Compressive strengths up to 200 Mpa Flexural Strengths up to 50 Mpa Modulus of Elasticity 45 to 50 GPa Ductile strong Durable High bending tensile strength Low capillary porosity (high endurance) High resistance to deicing salt Greatly reduced permeability to moisture, chlorides and chemical attack Increased resistance to abrasion, erosion and corrosion Speedy construction Properties of Concrete Compressive Strength 25 to 35 Mpa Relatively Weak Extremely Brittle Almost no tensile strength High thermal expansion and contraction with temperature fluctuations

Applications of UHCP: 

Applications of UHCP Scraper paths in treatment plants Architecture Bridges Narrow supports Filigree beams Thin or slab-like components Buttresses for high pressures
