Appl. No.:

17/955030

Inventors:

- Richland WA, US
Carlos A. Fernandez - Richland WA, US

Assignee:

BATTELLE MEMORIAL INSTITUTE - Richland WA

International Classification:

C04B 24/26

Abstract:

Examples of new polymer-modified cement formulations with self-healing capability at ambient temperature are described. These polymer-modified cements can be readily mixed with typical fine and coarse aggregates to build new concrete structures. One example of such a formulation includes a concrete comprising a MBA-BDA polymer having bond forming chemical functionality configured to form a bonding matrix between the polymer and at least one component of the concrete at a temperature less than 50 degrees C. wherein the matrix obtains at least 70% recovery of compressive strength after a damage event.

Abstract:

A system and process are disclosed for production of consolidated magnesium metal products and alloys with selected densities from magnesium-containing salts and feedstocks. The system and process employ a dialkyl magnesium compound that decomposes to produce the Mg metal product. Energy requirements and production costs are lower than for conventional processing.

Abstract:

An electrophilic acid gas-reactive fracturing and recovery fluid, proppant, and process are detailed. The fluid expands in volume to provide rapid and controlled increases in pressure that enhances fracturing in subterranean bedrock for recovery of energy-producing materials. Proppants stabilize openings in fractures and fissures following fracturing.
