Title:Develop a Cost Efficient and Effective Method for Cast-In-Place Ultra High Performance Concrete (UHPC)
Abstract: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 68±4 °F (20 ±2 °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.

Title:The Characterization and Mitigation of Radiation Effects on Nano-technology Microelectronics
Abstract:Defense Electronics Corporation (DEC) proposes an innovative radiation hardened by design (RHBD) and reliability improvement solution for silicon, III-V compounds (e.g. SiGe, SiC, GaN, InP, GaAs,), carbon nanotubes (CNT), and graphene. The method is based on analyzing chip-partitioned quiescent current signatures associated with failure modes common to these process technologies. Furthermore, the method leverages unique process properties for a novel recovery architecture. Quiescent current and chip level integrated recovery (CLIR) satisfy defect detection and diagnosis, fault analysis and/or fault propagation, and recovery. This method is designed to work efficiently in a radiation environment, although it is designed to work equally well with process technologies exhibiting failure modes unrelated to radiation. This method is similar to Concurrent Error Detection (CED) but possesses very distinct differences. In addition, the CLIR technique can be configured to detect IDDQ current signatures related to total ionizing dose (TID) as well as single event upsets (SEU). Candidate architectures include analog, digital, mixed signal, high power and radio frequency (RF) designs. Built In Current Sensor (BICS) and CLIR techniques for a RHBD solution mitigate radiation effects in scaled processes using SiGe, SiC, GaN, InP, GaAs, carbon nanotubes, and graphene.

Title:Radiation Effects Characterization Tool for SiGe Processes
Abstract:Ridgetop Group will develop a low-cost reliability and radiation effects characterization tool for state-of-the art silicon-germanium (SiGe) fabrication processes. The significance of this innovation is that SiGe bipolar complementary metal oxide semiconductor (BiCMOS) integrated circuits (ICs) have demonstrated extremely high performance for critical DOD applications, and SiGe has also been shown to have low susceptibility to total dose and displacement damage radiation effects, making SiGe a strong candidate for space applications. Ridgetop’s ProChek™ characterization tool will support the wider application of SiGe circuits in advanced spacecraft and missile systems, which can improve production yield and help reduce costs. SiGe BiCMOS circuits offer many benefits compared to their silicon CMOS counterparts for space microelectronics engineering. SiGe implementations have an advantage in terms of higher circuit speed, better transistor matching, and better noise performance. They also operate significantly better in extreme temperatures and are very robust against total ionizing dose (TID) radiation effects. The work will concentrate on IBM’s newest SiGe BiCMOS offering, the 9HP process, which provides ultra-fast SiGe hetero bipolar transistors (HBTs) to 300GHz fT and 385 GHz fMAX, as well as 90 nm CMOS devices. The result will be a more comprehensive reliability and performance characterization that can be incorporated into more precise design models having more accuracy.

Title:Develop a Cost Efficient and Effective Method for Cast-In-Place Ultra High Performance Concrete (UHPC)
Abstract:Fiber Reinforced Ultra High Performance Concrete (FRUHPC) offers enormous advantages to the United States as an advanced material to revitalize the nation’s infrastructure and in the building of new infrastructure that is sustainable, cost-effective and long lasting. In addition, the material has applications in defense of the nation that must be exploited. Adoption of UHPC in the U.S. has been slow and suffers from various logistical and economic headwinds. The proposers intend to investigate the methods of achieving high compressive strength and post-cracking hardening concrete and extend those methods into field applications where successful, laboratory-quality large cast-in-place pours can be made with optimized equipment on military and civil projects. Packing density optimization, sequenced high-shear on-site mixing, self-compacting and good flow-ability characteristics and protected curing methods will be the main focus of the work.

Title:Develop a Cost Efficient and Effective Method for Cast-In-Place Ultra High Performance Concrete (UHPC)
Abstract:Hipertex Armor Group, LLC proposes the development and validation of a fiber reinforced Cementitious product capable of being cast in the field while meeting the customer strength requirements without the need of steam curing. Specifically, Hipertex will utilize a new carbon macro-fiber technology developed for blast resistance combined with a family of mortar and concrete products based on tri-mix designs that can meet the compressive strength requirements of 25 ksi. Tri-mix cements are based on blends of portland cement, coal ash, and ground granulated blast furnace slag. Unique to the tri-mix formulation is the ability to increase the reactivity of the coal ash through in-furnace modification. The Phase I effort will validate the strength requirements put forth by the customer, while the Phase II effort will demonstrate the scalability of the product for in field casting, pumping and placement for cast-in place, tilt-up, and precast applications.

Title:Simple, Low Cost, Rapidly Deployable System for Forming Ultra High Performance Concrete (UHPC) in the Field.
Abstract:We propose the development of a simple, low cost technology for the field placement of ultra- high performance concrete (UHPC) that consists of a modified Gunite system and an improved UHPC formulation. The Gunite system includes modifications that overcome a number of problems related to the delivery of UHPC via gunnite including dust suppression and nozzle plugging associated with rapid setting fiber reinforced cementitious materials. An atomized water mist is produced that is much more effective at wetting very fine particles essential to making UHPC, improving uniformity, eliminating rebound, and producing a very dense concrete with greatly improved strength. The new system autogenously cured needing no external source of heat. The improved UHPC formulation is based on a calcium sulfoaluminate (CSA)--Portland (OPC) blended cement, anhydrite, ultra-fine fly ash (UFA), Polyvinyl alcohol (PVA) fibers, steel fibers, a proprietary accelerator and graded quartz river sand. This formulation results in a much higher rate of strength development, as well as the prerequisite total strength. The UFA provides a strong pozzolanic component and contributes to the overall density and long term strength of the final UHPC. The UHPC gunnite formulation also has superior adhesion and bonding to a range of fibers and preexisting surfaces.
