Develop a Cost Efficient and Effective Method for Cast-In-Place Ultra High Performance Concrete (UHPC)
BOT proposes project codenamed DTRAcrete an innovative FR UHPC that is industrial-scalable for low-cost, locally-sourced, fast production, cast-in-situ, deployable for various regions/countries with US military presence. These are the showcased features: Economized materials DTRAcrete will re-introduce coarse aggregates. DTRAcrete will use less steel fibers. Total material cost savings will be at least $248 per cubic yard. Efficient production Mixing involves both physical and chemical enhancements. DTRAcrete is mixed at 5 minutes per batch, using a conventional concrete plant. Transporting, Placing, Curing are all improved. Production of DTRAcrete is fast and consistent, employing existing large- scale concrete batch mixing plant and concrete transport/pumping infrastructure. large scale, cast-in-situ DTRAcrete can be demolded approximately 24 h after casting, and then cured at a temperature of 684 degrees F (20 2 degrees C) and no less than 95% relative humidity, easily achieved by simply placing a tarp over the surface. Ultra high performance and beyond DTRAcrete can easily reach 26.5ksi and beyond. It can easily have a post-cracking tensile strength of 3ksi with the new fiber strategy. Excellent weather and corrosion resistance Expected 100+ years of zero maintenance in all varieties of climates and exposures.
