Excerpts

To clearly demonstrate the degree of CS weakening, Figure 6 shows that with the increase in graded ARGF admixture, the concrete CS increment ratio fluctuates, but generally, it presents a decreasing trend.

It can be seen from Figure 10 that under different temperature rising rates, the maximum pyrolysis rate in the DTG curve shows an increasing trend corresponding to the temperature, and the main reaction interval also increases slightly.

An interesting trend is seen, where generally: (a) density increases in time, even when fresh and hardened state are compared [ 83 ], and (b) density increases in ssd as well as in oven-dried state.

Considering relation f c -180-ssd:f c -28-ssd, there is an obvious trend, since compressive strength increases with time, complying with theory.

The weight loss during torrefaction showed a decreasing trend over time.

Establishing the Carbonation Profiles In the previous section, a decreasing trend of the υ 1 CO 3 band over the depth in both the FA/PC and GGBS/PC pastes was clearly recognized.

For all PEG-based hybrids, a decreasing trend of the residual masses (ascribable to ZrO 2 ) is found after the complete degradation of the polymer with increasing the PEG content, with the exception of PEG-free pure ZrO 2 material.

The film density was proportional to the critical angle θc in the reflectance curve, and θc showed a decreasing trend as the O 2 flow ratios increased, confirming the decreased trend of film density displayed in Figure 3 h.

Our results in Figure 4 indicate that, in all the curves, the SLP max decreases with increasing σ and there is a clear trend of increasing relative SLP max when the value of K changes from the NB-region (9 kJ/m 3 ) to K c (20 kJ/m 3 ) and then the B-region (41 kJ/m 3 ).

An increasing trend in viscosity as the content of each type of fiber increases can also be observed.

Furthermore, it shows a clear trend from monomeric, over dimeric to trimeric compounds accompanied by increasing activities, particularly for NCI-H1581 line, due to more active groups in the molecule.

Moreover, from the single cross-sections, it is difficult to establish a clear trend over the type and 3D spatial distribution of the pores.

It can be clearly seen that the maximum radial and axial rubbing force and temperature present an increasing trend with the axial incursion rate.

As shown in Figure 11 , it was possible to observe an increasing trend of the load curve in the A and B series after the formation of the first crack.

The hardness and Young’s modulus obtained from nanoindentation follow a clear trend with bias pulse length.

With the increase of frequency, the friction coefficients of the three rubbers show a slightly increasing trend.

At the same time, the number of annual publications had also shown an increasing trend.

Clearly, the parameters G′ and G′′ show a decreasing trend with increasing temperature.

Similarly, the rising concentration of PPA also leads to an increasing trend of G*/sinδ.

Tensile Strength With the increase in rotational speed of the extruder screw in the studied range of variability, it was observed that the values of tensile strength of the film in longitudinal direction show an increasing trend in the case of polyethylene, polylactide and plastic based on potato starch, while for the material based on corn starch it decreases ( Figure 14 ).

Then, keeping the continued incorporation of Gr would not be quite significant to the TS reduction and high-temperature properties improvement of asphalt binders.

Furthermore, uniaxial tension samples showed a trend of higher toughness values with time for CMOD < 2 mm which decreased at the end of the tail (i.e., at CMOD = 4 mm), see Figure 7 d; however, this was the case mostly for samples cracked at 0.15 mm.

The compressive strength and the flexural strength have a decreasing trend with the increase of the wet-dry cycles in the acid rain solution or in water.

Bulk Density and Thermal Conductivity From a comparison of the results of the bulk densities and thermal conductivity coefficients of fiber-cement mortars after 28 days of hardening composites ( Figure 7 , Figure 8 , Figure 9 and Figure 10 ), it is clear that as the content of cellulose fibers in the mixture increased (C/WPF ratio decreased), the bulk density and conductivity of the mortars had a decreasing trend.

It can be seen that the unconfined compressive strength showed an increasing trend of the S/L ratio until the S/L ratio of 1.5, then the result of compressive strength gradually dropped with the increase in the S/L ratio.
