Experimental and computational characterization of glass microsphere-cementitious composites

Mechanical characterization of Portland cement with hollow glass microspheres of two different crushing strengths, 500 (FM) and 10,000 psi (3 M), was carried out to determine both quasi-static and dynamic responses of the cementitious composites. In the dynamic tests, the time resolved high speed camera photos of the deforming specimens revealed the stress levels at which incipient damage occurred. The dynamic split-Hopkinson pressure bar...
