High-Strain-Rate behavior of Hydrated Cement Paste.

Abstract

Two distinct trends in the stress-strain behavior of cement pastes hydrated for 28 days were noted. At low strain rates (< 250/sec) the ultimate stress increases almost linearly, whereas at higher rate (> 250/sec) it reaches a somewhat limiting value. Porosity of the pastes appears to be the dominant factor in determining the strain-rate response. Fractures and cracks under loading are seen to go through the C-S-H phase of the paste.
