Relative dynamic elastic modulus is a non-destructive testing indicators，It should be larger than 60%, as follows: (3) In the formula： P—Relative dynamic elastic modulus after n times of Freeze-thaw cycles (%); fn—Transverse fundamental frequency after n times of salt freeze cycles (Hz); f0—Transverse fundamental frequency before the test (Hz); N —the number of Freeze-thaw cycles. 3.3 Test Results Table 8 C40 Concrete Freeze-Thaw Test Data No.
The experimental data show that, with the decreased water, the deicer-frost resistance of concrete increases.
According to the characteristics of bridge engineering, combining with the experimental data presented the recommended values of the composition material parameters based on frost resistance of bridge concrete in the ​​alpine region of Xinjiang.

These billets were then cold rolled to copper sheets with thickness reduction about 10% per pass (Fig. 1(b)).
Final thickness was 4.7 mm and the total thickness reduction ~75%, equivalent true strain ~1.6.
The initial local texture (Fig. 2(d)) represented by calculating {111} pole figure (PF) from XRD data illustrates that it was moderate strong recrystallization texture before ECAP.

Then, the observed peaks of the diffraction patterns were identify by comparing with similar magnesium-aluminum hydrotalcite phases available on JCPDS data bank [20].
From raw data two calculation procedures were made to obtain the specific surface area through the BET model [22] and the pore size distribution in the mesopore and macropore ranges, through the BJH model [23].
Consequently, the band II intensity is lower for samples calcined at 200 ºC, due the reduction in water interlayer amount.
In spite of to have no differentiation between these two anionic species on literature, it seems the nitrate vibration is centered at 1390 cm-1 (band V) due the significant reduction in its intensities if compared to the band centered at 1520 cm-1 (band IV).
