Ultra-high performance concrete (UHPC) can be used to create the simple, strong, long-lasting connections needed for successful construction using prefabricated bridge elements. The durability of prefabricated spans, and how quickly they can be constructed relies on the connections between the elements.
Q: What is concrete?
A: Concrete is a composite material made from coarse aggregate (rocks), fine aggregate (sand), portland cement, and water. When mixed, the portland cement and water combine together in a chemical reaction to create the glue that holds together the...

Title no. 110-M17
INTRODUCTIONSustained postcracking tensile resistance is a fundamental mechanical characteristic of ultra-high-performance fiber-reinforced concrete (UHPFRC). This research program developed a simple, reliable direct tension test (DTT) method that can generate the...
Title no. 105-M68
Accurate determination of the compressive strength of very high strength concrete is currently a difficult proposition due to large testing machine capacity requirements and the need for cylinder end preparation. An experimental program was conducted to determine whether...
