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

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