Compressive strength most significant effect

Calcium chloride increases compressive strength of cement pastes especially at earlier times. The most significant effect on compressive strength occurs with portland blast furnace cement and marginally with portland-pozzolan cement. The compressive strength of cement pastes in the presence of 2% CaCl2 improves by about 50,41,11,9, and 8% overthe reference at 6 hours, 1, 3, 7, and 28 days, respectively.P" ]... 

The Bauschinger effect is most pronounced at room temperature plastic deformation (1 to 5% tensile elongation) at room temperature always introduces a significant loss in compressive yield strength (see Fig. 1), regardless of the initial heat treatment or strength of the alloys. At 2% tensile strain, for example, the compressive yield strength of Ti-6A1-4V drops to less than one-half the value for...
