UHPC

COD’s mobile concrete plants deliver UHPC (ultra-high performance concrete), now used on the most demanding infrastructure including bridges and roads, creative architecture, and cost-effective public and private buildings. UHPC delivers superior strength and resistance to compression and flex with improved longevity, efficiency, and aesthetics.

Bridges, tunnels, and roads

Strength and durability make UHPC the ideal solution, due in part to its resistance to freeze & thaw as well as impact or abrasion. High ductility provides superior resistance to joint flex from heavy truck traffic, increasing structural stability, and it is a lighter option than steel — allowing thinner, longer spans. Portland cement, supplementary cementitious materials, reactive powders, limestone and/or quartz flour, fine sand, high-range water reducers, and water are the building blocks of this remarkable product. The American Society for Testing and Materials has established ASTM C1856/1856M Standard Practice for fabricating and testing UHPC specimens. When combined with metal, synthetic, or organic fibers it can achieve flexural strengths up to 7,000 psi (48 MPa) or greater. With your specifications, we can set up the formulation ahead of time and mix your exact requirements on the spot.

Rapid Set Cement (CSA)

COD’s mobile concrete plants are uniquely designed, making us the cost-effective solution for working with Rapid Set Cement, also known as CSA (calcium sulfoaluminate cement). We deliver exact proportions of the raw materials used to manufacture CSA, yielding the highest performance, durable and long-lasting materials available.

Features of our Rapid Set CSA

• Low shrink – ensures virtually no cracks
• Ready to drive on or build on in 1 hour
• Reaches final strength in 1 day
• Low drying shrinkage (70% less than ready-mix)
• Chemical resistant
• Zero reaction to alkali-silica reaction (ASR)
• Extended lifetime – up to 80 years before replacement

When you can’t stop a job and wait for regular cement to cure, COD has your back: buildings, stairs, streets, sidewalks, bridge deck overlays, runways, footings.
