Characterization and Performance Optimization of a Cementitious Composite for Quasi-Static and Dynamic Loads

Abstract

The U.S. Army Engineer Research and Development Center conducted multi-scale material research directed towards enhancing the response of a rapid-set, high-strength geopolymer cement under quasi-static and dynamic loads. Four unique tensile experiments were conducted to characterize and optimize material response of the fiber, matrix, and interface. Single-fiber direct tension and single-fiber pull-out experiments were conducted with quasi-static and dynamic loads. Flexure from third-point loading and direct uniaxial tension of the fiber reinforced composite experiments was conducted with quasi-static loads. Initial results are presented for the ongoing research.
