Self-Contained, Expendable, Pyrotechnic Blankets for Heat-Treating Internally Sealed Concrete

摘要

This report presents the analysis, design, and development of a solid pyrotechnic heating blanket system for heat treating Internally Sealed Concrete. Design considerations included: the ability to heat to a required thermal profile; life-cycle costs; ease and safety of manufacturing, shipping, and use; thermal efficiency, reliability; and byproduct production and disposal. Laboratory and field samples of the pyrotechnic blanket were produced and tested. This report will be of specific interest to researchers and operations personnel concerned with pyrotechnic heating formulations, specifically aluminum, iron sulfur compounds, and their characteristics, control, and manufacturing processes to achieve relatively slow heating profiles.
