Based on the results in Table 3 and Figure 3 and Figure 4 , the key findings are summarized and discussed below: The pore properties of CD-based biochar products indicated an increasing trend as the microwave output power increased from 300 to 800 W at a holding time of 5 min, suggesting an increase in the surface area and pore volume due to more pore development.
Excerpts
The results showed that with the increase in GP replacing FA, the fluidity of the alkali-activated materials gradually decreased, the shear stress and the equivalent plastic viscosity both showed an increasing trend, and the paste gradually changed from shear thinning to shear thickening.
Unlike water curing, the development of compressive strength of the air-cured samples showed an increasing trend, and the strength of samples added with Nes was higher than that of #1 samples with pure MgO.
The stiffness of the three girders showed a decreasing trend due to the continuous development of concrete cracking in the whole working stage with cracks.
However, as the water-binder ratio increased, the compressive strength of mortar samples showed a trend of rapid decline.
a clear trendgold
A clear trend is the fabrication of multifunctional coatings that require the combination of different properties in the same material.
A significant drop in current densities is observed in the first 2 h of testing, after which currents are relatively stable but still show a decreasing trend.
AE activity shows an increasing trend; this occurs because microcracks begin to form, nucleation and convergence occur, and, finally, the microcracks propagate stably [ 51 ].
Strength and Deformation Properties As shown in Figure 6 and Figure 7 , with the increase in the applied static axial pressure, the dynamic strength showed an increasing trend and then a decreasing trend, reaching its maximum at an axial pressure of 14 MPa (10% UCS).
an overall trendgold
The peak strain shows an overall trend that increases and then decreases with the increase in axial pressure.
In addition, there is an increasing trend in their consumption.
This study indicates that the slump of concrete is reduced by the inclusion of recycled steel fibers and shows a decreasing trend with an increase in the fiber content.
The influence of the depth from which specimens are sampled from the joint may be significant [ 30 , 42 , 43 ].
After the peak load, the curve shows a decreasing trend; the load of the RC columns showed a rapid reduction of 5–10% followed by a more gradual reduction, and ductile failures occurred in the specimens.
In dry friction conditions, a decreasing trend of the COF with increasing contact pressure was observed.
Additionally, PI and T 800 also showed an increasing trend as the filler-asphalt ratio was increased.
The complex shear modulus G* of asphalt mortars showed a decreasing trend, while the phase angle showed a rising tendency with increase of temperature.
From Figure 12 a–d, it can be seen that with the increase in time, the thickness of the repair material added with three different diluents showed a trend of rapid decrease followed by a slow decrease during the curing process.
Contrastingly, as the cement substitution rate increases, effective w/b decreases and the Ss of mortar blends shows a decreasing trend.
The peaks of progressing loops were connected as the number of cycles proceeded in Figure 11 , resulting in a decreasing trend with nearly the same pace for all models.
Additionally, the specific surface areas of the aerogels obtained by different treatment techniques showed a decreasing trend (S SCD > S FD > S APD ), corresponding to the values of 248.7–267.4 m 2 /g, 241.7 m 2 /g, and 218.5 m 2 /g, respectively.
The thickness of both layers showed a decreasing trend with the increase in temperature.
With the extension of the test cycles, the thickness of the two layers displays an increasing trend.
After high-temperature treatment (40 and 60 °C), the cubic compressive strength, axial compressive strength, and elastic modulus of HDC show an increasing trend, and the rate of increase in performance indicators is greater with higher temperatures.
When the content of SiC nanoparticles is 0–4%, the shrinkage rate shows an increasing trend in the length, width, and height directions.
