Coating, Layer, and Bulk Material for Extreme Thermal Protection

BACKGROUND High-temperature applications, such as rocket engine combustion output, can reach temperatures as high as 3,315 °C (6,000 °F). Enough heat to fuse a concrete surface, like a launch pad, into glass. Fused concrete has a limited lifetime as structural integrity is compromised in some cases immediately, resulting in potentially dangerous...

Modular Concrete Pavement Expansion Joint

BACKGROUND Concrete pavements, including roads, parking lots, and industrial pavements, are critical to transportation and economic function. Joints are cut into the pavements, allowing for temperature-driven contraction and expansion to prevent further damage. Unfortunately, due in part to elimination of expansion joints and the preference of low-shrinkage...

Measuring workability of slip form concrete using vibrator and accelerometer

BACKGROUND When mixing concrete, vibration helps to consolidate fresh cementitious mix by reducing the volume of voids, air pockets, and entrapped air, increasing density and strength of the resultant material. However, vibrational consolidation can be overdone, pushing out needed water from the mix. Currently, monitoring concrete to ensure proper...

Real Time Measurement of Moisture and Hydration of Concrete

BACKGROUND Concrete derives its strength from calcium silicate hydrate, a product of the hydration reaction that takes place when water is mixed with cement. A process known as curing, which involves providing continuous moisture and maintaining or providing heat to the concrete mixture, promotes the formation of calcium silicate hydrate. Curing conditions...

3D Printing System for Vertical Construction

BACKGROUND Most 3D printing systems sequentially apply their layers from above. Such systems have distinct challenges when creating vertically reinforced concrete structures such as walls or columns. Most vertical reinforced concrete structures contain reinforcing bars that give the structure strength after the concrete has cracked. It is possible...
