The QUIKRETE® Companies and the U.S. Department of Energy’s (DOE) Oak Ridge National Laboratory (ORNL)entered a cooperative research and development agreement to design next-generation concrete for use in the production of large-scale structures through a 3D printing process. Using additive manufacturing system developed by ORNL, the collaboration with QUIKRETE® will deliver specially-formulated concrete that establishes new construction capabilities.

In alignment with the DOE’s Advanced Manufacturing Office’s Multi-Year Program Plan, QUIKRETE® and ORNL are developing a concrete mix with the strength, curing time, and durability to construct buildings, energy installations, transportation infrastructures, and other large-scale structures faster, more affordably and with less energy consumption. Designed as a pumpable, low- or zero-slump material that sets quickly and gains strength rapidly, this new concrete will be ideal for printable construction projects. In addition, the one-of-a-kind concrete will meet tensile strength, compressive strength, ductility and other structural performance characteristics required as a viable building material.

The partnership will leverage ORNL’s scientific expertise and its unique facilities along with QUIKRETE®’s robust experience in the plastic and hardened properties of cement-based building materials.
