These mortar samples showed an increasing trend of shrinkage over time.

a clear trendgold
In previous studies, a clear trend was identified where the compressive strength and tensile strength decrease and chloride penetration increases with increasing number of recycling, which is consistent with the results of the C-100 and E-100 concretes in this study.
The most probable aperture and critical aperture of the pure paste show an increasing trend as the freeze–thaw cycles increase, as shown in Figure 13 a.
With an increasing number of freeze–thaw cycles, there is a decreasing trend in the relative dynamic elastic modulus of the HD–MPCC.
Moreover, upon examination of Figure 12 a,b and comparison of the peak impact load of SFRC beams, it was noted that the peak load exhibited an insignificant effect on the stiffness of SFRC beams as the steel fiber content increased during the impact test, while the peak deflection at mid-span showed a decreasing trend.
Furthermore, the density of the specimens exhibited a decreasing trend as the storage time increased, indicating an increase in porosity.
In the viscoelastic continuum damage (VECD) model, the cumulative damage was related to the modulus, while with the increase of asphaltene and resins, the fatigue life showed a trend of first increasing and then decreasing.
A decreasing trend of both widths of built tracks and their depth of penetration was observed at low volume fractions of 5% and 10% and at high volume fractions of 25% and 30%.
As seen in Figure 10 a, it is evident that with the increase in vibration compaction passes, the TAV amplitude of the mortar shows a decreasing trend and finally tends to be stable.
Beyond 60 cycles, a decreasing trend in mass change led to mass loss ( Figure 4 ) associated with a decreasing trend of RDME values ( Figure 5 ) exhibiting freeze–thaw deterioration, which was supported by the decreasing trend of UPV ( Table 6 ).
It is interesting that the cross-link density of the materials with CBS showed an increasing trend with an increasing ratio of EPDM in rubber combinations.
Generally, compressive strength and elastic modulus followed a decreasing trend with increasing porosity.
The conductivity of the films exhibited an increasing trend with increasing temperature, reaching a peak value of 1.12 S/cm at 80 °C.
a notable trendgold
As the NaAlH 4 content increased, a notable trend was observed in the curve depicting the ratio of hydrogen release at the temperature peak to the increase in temperature.
As the three parameters increased, the cross-sectional area of the fiber bundles generally showed a trend of first increasing and then decreasing.
a clear trendgold
This demonstrated a clear trend showing that the HE susceptibility increased with longer aging periods and larger sizes of k-carbides, as evidenced by the significant reduction in elongation. 3.3.
In this process, the dominant effect of air content on thermal conductivity results in an increasing trend with the rising water–cement ratio.
As the water content increases, the amount of moisture that can be lost during the same preservation process also rises, causing a decreasing trend in the wet density of the material with the increasing water–cement ratio.
a clear trendgold
However, a clear trend was not reported.
When the statistic F j < F 0.05 ( 4 , 17 ) , it is considered that the statistic corresponds to a factor with insignificant influence and low sensitivity; when the statistic F 0.05 ( 4 , 17 ) ≤ F j ≤ F 0.01 ( 4 , 17 ) , it is considered that the statistic corresponds to a factor with average significance and medium sensitivity on the measured test indicator; and when F 0.01 ( 4 , 17 ) < F j , it is considered that the statistic corresponds to a factor with highly significant influence on the measured test indicator and high sensitivity.
The complementary reinforcing effect provided by adding a small amount of SZMO NTE ceramics was highly significant.
Except for the area affected by cavitation, the temperature profiles exhibit a decreasing trend along the direction of positive pressure differential of mediums.
The same changing tendency in F and q could be observed at the three temperature gradients: there is a critical speed for performance change, which shows an increasing trend before the critical speed and a decreasing trend after the critical speed.
Subsequently, an increase in the amount of binder resulted in an increasing trend in electrical resistance values.
The density of the material with an equal volume share of magnetite aggregate (CM1-2 ÷ CM8-16), shows quite significant fluctuations, with a clear increase with the grain size of the aggregate.
