Figure 1
shows the frequency distribution of the elasticity modulus ( ) of the
standard UHPdC specimens. The values were determined according to
BS1881: Part 121 (1983) using cylinder specimen with 100 mm diameter and 200 mm
height under force control rate of 20 MPa/min. The strains were capture using
electrical strain gauges. The tested UHPdC shows to have average
values of about 45 GPa and standard deviation of 1.45
GPa. The Poisson’s ratio also determine to be between 0.18 to 0.2.
