Excerpts

Among the different strength grades, the C60 and C80 concretes exhibited a notable trend in the change in the PA values.

In the axial direction, the PEEQ showed a trend of high in the middle and low on both sides, and in the radial direction, it showed a trend of high in the middle of the two ends.

As the aggregate density increases, a corresponding increase in the parameters d and h is observed, while parameters b , c , and i exhibit a decreasing trend.

From Figure 4 and Figure 8 , it can be found that the predicted curves of the modified J-C model only show a decreasing trend.

Additionally, there appears to be a decreasing trend in crack formation after exposure to ASR, and an increase in immersion depth of the solution results in fewer cracks.

The data provided in Figure 3 on the standard frequency bands indicated an increasing trend in Category I for the sound absorption coefficient values at 250 Hz, 500 Hz and 4000 Hz, beginning with the composition of cement, then plaster, hydrated lime and clay.

When these results were viewed in terms of material density, there was a clear trend that higher density correlated with higher compressive strength.

Figure 3 d indicates that as the initial distance increases, the voltage and current signals generated by the proximity sensor show a decreasing trend, dropping from 60 V and 45 nA at a distance of 2 mm to 28 V and 16 nA at 16 mm.

It is evident from the figure that the matrix performance exhibits a decreasing trend with increasing immersion time.

As shown in Figure 7 , no matter what the adsorption level of Cd was, as the water content increased, RES remained relatively stable, FMO, CAB, and ORB showed a downward trend, and EX showed an increasing trend.

The data in Table 4 reveal a highly significant negative correlation between pH and EX contents.

Refining the electrochemical synthesis method for obtaining nanoparticles is highly significant, as improved control over the synthesis process—including the ability to regulate nanoparticle shape and size—directly impacts their application potential.

Despite the fact that there is not much of it in the friction material, the difference in the price of the final product may be significant.

Introduction In recent years, the pursuit of lightweight materials has emerged as a significant trend in the development of metal structural materials.

A clear trend of powder refinement with increasing Y 2 O 3 concentration is observed, further confirmed by the scanning electron microscope images in Figure 2 .

Tensile Property Analysis As the temperature increases, both the ultimate tensile strength and yield strength of the materials show a decreasing trend, while the elongation after fracture exhibits an increasing trend.

Figure 8 b shows a decreasing trend in the tensile elastic modulus of RM with the increase in VAE content.

While the particle size is decreasing, the phenomenon of agglomeration is quite significant, as indicated by the green dashed box in the figure.

Interestingly, water absorption exhibited an increasing trend with increasing AcB content across both curing environments.

The selection of these metrics is based on both their statistical robustness and their applicability to real-world scenarios, guaranteeing that our evaluation is both theoretically robust and practically significant.

Similarly, H1415 continued to decrease; however, the changes were small and barely significant in the first 30 min of exposure and again after 90 min of exposure.

(2) With an increase in the phosphoric acid ratio N, the size of the bubbles showed a decreasing trend and peaked between N = 1 and N = 4.

The results demonstrate a clear trend as the cement content increases, the load required to achieve a specific penetration depth rises significantly.

The analysis indicates that the overall model is highly significant, with a p -value less than 0.0001 and an F-value of 243.52, suggesting that the model effectively captures a significant portion of the variation in TAE.

Conversely, a decreasing trend is noted for laterally compressive stresses present at both starting and ending points.
