Excerpts

The strength of the mortars exposed to chloride-sulfate coupling showed a decreasing trend for all groups, and the phenomenon was exacerbated by the further coupling of carbonation, where the most obvious strength loss was in Specimen C without admixture, whose strength loss was 13.4% under the three-factor coupling, indicating that the mineral admixture, in particular the metakaolin, could improve its resistance to erosion to some extent.

Many research results show that with the increase in cement content, the compression index, pre-consolidation pressure, and unconfined compressive strength of soil show an increasing trend, and the strength of the stabilized soil with lower water content is higher [ 4 , 5 , 6 ].

With the Ni content increasing, t ig shows a decreasing trend.

As shown in Figure 9 d, the detail data collected from [ 11 , 12 , 13 , 26 , 27 , 40 , 41 , 42 ] generally follow the empirical Hall–Petch relation, which presents an increasing trend in hardness with the reciprocal square root of the grain size.

Practically significant physical properties of crystals depend on several factors.

In this case, an increasing trend was observed with the amount of filler added.

The flow number values of all types of asphalt mixtures decreased with the increase in temperature, whereas the creep rate values presented an increasing trend.

However, an interesting trend was that all of the recalculated crack widths from the image analysis were larger than the estimates from the gas diffusion experiment, whereas the microscopically measured crack widths did not exhibit any trend with the estimations.

In other words, the critical phase transition stresses (cf., Table 2 ) show a strong trend.

Introduction A low-carbon economy has become an important trend for sustainable development of today’s society in the grim context of global warming [ 1 ].

Generally, the maximum height S p decreases with the increase of shear times, as in the four groups of interfaces with 4 MPa normal stress (AD-1, AD-2, AD-3 and BD-1); however, S p corresponding to first shearing is greater than that before the test and then shows a decreasing trend with the increase of shear times.

The tensile strength and tensile deformation of ordinary sand with a 0.075–0.3 mm particle size show an increasing trend alongside the increase in age, whereas when the particle size exceeds 0.6 mm, a decreasing trend occurs.

Compression Test According to Table 4 , which presents the results of the concrete cube specimen’s compression after 28 days, the compressive strength of all the mixes does not show a conspicuous change as the increment varies in the small zone while forming a slight trend.

However, as the ageing temperature progressed to 490 °C and 520 °C, both bending forces began to show a decreasing trend.

The present results show that the exposure of zirconia surfaces to H 2 O 2 did not alter their topographic appearance and roughness values ( Figure 1 A), but, in contrast, partially significant changes were observed in the physical and chemical properties.

The present study shows about 50% decrease in recrystallized fraction with 0.1 wt.% Cr addition in 7449, which is quite significant considering that only a maximum of 4% drop in hardness was observed after artificial aging to the T6 condition. 4.3.

However, in the past five years a strong trend toward the usage of machine learning (ML) algorithms has arisen [ 19 , 20 , 21 ].

Furthermore, the results showed a clear trend towards using a specific steel grade.

However, if the grid network has a low aperture ratio, an air layer behind it or several stacked layers, its sound absorption may be significant.

However, the presence over the past five years of several patents on green laser technology (US 8675698B2, US 2022/0314366A1), on converting a laser radiation of longer wavelength to a laser radiation of shorter wavelength (US 9042419B1) and on the use of multi-lasers with different wavelengths (US 2017/0021455A1, US 2015/0246412A1) suggests a clear trend in the PBF-LB/M machine market towards this technology.

The delta CAL values calculated for 12 months could be considered marginally significant at the selected level of significance of 0.05.

The investigation was dedicated to graphene pastes, which represent a strong trend in the development of screen-printing technology. 2.

The water contact angle values show an increasing trend linked with GO concentration in all GO/BC nanocomposites ( Figure 13 ).

With the increase in age, the flexural strength of the recycled brick micropowder UHPC showed an increasing trend as a whole.

Thus, as the number of gradient film layers increases, the transmittance of the film shows a decreasing trend. 3.5.
