However, at 180 d, the FS of each test group showed a trend of first increasing and then decreasing.

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.

Conversely, in the case of single-term Prony series, the R 2 coefficient exhibited a decreasing trend for the higher indentation rates.

However, there is also a clear trend.

It showed a decreasing trend in values as the content of HEMA increased.

Rheological behaviors of samples showed an increasing trend of elastic modulus upon gelation while moderately maintaining volume phase transition temperature.

Since the difference between the average crack width measured at the center of the panel (position A) and at the edge of the panel (position C) was within the test variability and did not follow a clear trend, the crack width along the crack development length was assumed constant in the theoretical approach for deriving the stress vs. crack width by inverse analysis RPT-3ps ( Section 4 ). 3.3.3.

Regarding the final setting times (FS threshold not included in the standards), however, there was a clear trend towards acceleration, with the exception of HsT 10% paste.

These crack appearance observations helped us to visualize a possible trend where OFI mucilage addition increased the time before corrosion propagation, or the time before the appearance of corrosion surface cracks.

Once again, almost insignificant is the effect of the filler content on this parameter, considering the standard deviation of experimental results.

With the movement of the heat source to the upper layers and far away from point 1, the temperature and thermal stress also showed a decreasing trend.

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 trends of the CR and DG fibers are opposite; the CR fiber led to the linearly increasing trend while the DG fiber showed a decreasing trend.

The production of composite laminates based on PLA resin has not been the subject of intensive research, so far, but the appearance of this type of materials on the market indicates an interesting trend in the use of biopolymers The use of PLA as a matrix for composites and laminates was already investigated in case of ramie fibers [ 60 , 61 ], bamboo [ 62 , 63 ], cotton [ 64 , 65 , 66 ], kenaf [ 67 ] or flax [ 26 , 68 , 69 , 70 ].

Considering the effect of the sintering temperature increase from 1000 to 1200 °C, in the case of Sm and Sr, the two parameters (shrinkage and compression strength) exhibit a slight gain, as an expected trend for a ceramic body.

In Figure 6 and Figure 7 , an interesting trend in jet length, diameter, and velocity is observed with diverging channels of varying angles between 12.5° to 17.5°.

In the groups with a higher concentration of HEMA (resins 4 to 6), a decreasing trend with an increase of BisGMA fraction and thus also viscosity of the adhesive was observed ( DC POSS4 = 56.4%, DC POSS5 = 17.1%, DC POSS6 = 9.6 %).

Compared with the initial unstrained state (λ = 1), when stretch λ = 2–8, the open circuit voltage of SH-TENG shows a decreasing trend, when λ = 8, the open circuit voltage only accounts for the initial unstrained half of the output in the state reaches ~11 V.

The total alkali content itself seems to be of a minor significance because SAP A (with the highest alkali content) had a similar pH to SAP E.

However, due to the hugely significant variation in climatic conditions on a geographical basis, asphalt materials need to be selected carefully in order to increase the longevity and lifespan of the road pavement thus reducing the possible huge cost of road maintenance [ 1 ].

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

In addition to this feature, as shown in Figure 5 , it is difficult to differentiate a clear trend induced by the addition of PP and PN fibers and an increase in the volume fraction of the synthetic fibers.

In Figure 5 , the particle size distribution of microcapsules indicated a decreasing trend with increasing stirring speed.
