Replication Data for: "Effect of Strain History and Mixture Proportions on Early Age Cement Paste and Mortar Stress Relaxation"

This study focuses on measurements of the relaxation modulus of cement paste and mortars at early ages (1-28 days). The influence of sand particles, aging, and w/c ratio on the viscoelastic behavior were investigated. A sensitivity analysis is used to compare the relaxation modulus obtained approximating the strain state as constant versus one obtained considering the real strain history observed during testing;
