Excerpts

However, this paste showed the most rapid increase in BET surface area, as a significant difference was apparent even after the first 30 min and especially after one hour, i.e., between the initial and final setting time indicated by the Vicat needle (see Table 2 ), as well as between 60 and 120 min.

Since typical conversion of CO 2 to carbonate is very slow and inefficient under the conditions of ambient temperature and pressure, there has recently been an increasing trend in research on maximizing the mineral carbonation reaction using supercritical CO 2 .

Its effect on surface temperature is quite significant during the day but at night, due to low heat capacity of the plaster layer, the stored heat is quickly lost and the temperature rises only slightly.

From the experimental results obtained, the following conclusions can be drawn: The fresh properties of the developed mixes showed a decreasing trend with the increases in silica fume and RCA and with the inclusion of steel fibres.

According to Figure 9 a the OP-TMF life of the reference material, Esshete 1250, does not show a clear trend when the material is aged before OP-TMF testing.

In addition, OC (3rd column in Table 4 ) shows a clear trend, as it increases when the amount of SFG increases.

The σ F increased with an increase in RS p up to RS p V F : 0.45, and thereafter, a decreasing trend was observed.

In addition, a low amount of mica minerals of muscovite and biotite group and almost insignificant amount of clinochlore were found.

Highly significant safety aspects include the hazards of battery vent gas (BVG) or smoke and difficulties involved in firefighting, which is caused by failures of on-board large-capacity batteries.

As shown in Figure 4 a, the temperatures of CBFM-A show a decreasing trend after an increase.

Thermal Plasma Reduction of Minerals toward Nanoparticles of Oxide Recently, there has been an increasing trend toward the preparation of nanoparticles by using thermal plasma technology.

A clear trend was visible with the evolution of the M/S ratio.

All the samples showed a decreasing trend of thermal conductivity with temperature, implying that the phonon–phonon (Umkalpp process) is dominating the phonon transport (see Figure 5 ).

There is a clear trend that the stiffness D 11 generates higher sensitivities for all quantities than D 22 .

Moreover, an increasing trend of the gel fractions with increasing crosslinking temperature from 65 to 75 °C was observed.

However, after adding different amounts of CaO, the overall changing trend of the two parameters with different temperatures can be viewed as a decreasing trend with the temperature increasing.

That is, the cumulative dissipation energy shows a decreasing trend with increasing strain control levels.

In the case of k 2 and h coefficient values, there was an increasing trend of these parameters in the following series: La(III) > Pr(III) > Nd(III) > Ce(III).

Upon adding both reinforcements to Al matrix to form a hybrid nanocomposite, an interesting trend was observed.

Figure 2 a–d highlights a significant trend.

The averaged diameter size examined with a help of ImageJ software shows a decreasing trend with increasing homogenization time.

It can be seen that with temperature increasing from RT to 550 °C, the UTS and hardness of the steel show a decreasing trend overall, although the UTS decreases more, while the hardness only slightly decreases.

In this subject an increasing trend was observed in recent years, focusing on thermal conductivity, temperature distribution, heat flux analysis, water system temperatures, setpoint optimization, and energy consumption reduction [ 9 , 34 , 35 , 36 , 37 , 38 , 39 , 40 ].

The relationship between micro-pore structure and compressive strength suggested that with the decrease of open porosity, the compressive strength showed an increasing trend.

Meanwhile, as the initial concentration gradually increased, the concentration of sodium ions rose and the viscosity of the solution increased, so that the content of each impurity in the product showed an increasing trend after the concentration exceeded 60 g L −1 . 3.1.2.
