In the preceding few years, this number has been rising steadily.
The need to consider environmental concerns in the construction industry globally, as well as the economic and social contexts of developing nations, particularly in Central Africa, has once again brought attention to this material, leading to the current completion of a number of projects aimed at optimizing its value.
On the other hand, it contributes to their entanglement, since these wastes are generally irregularly shaped rods, which prevent the grains, especially those of very small size, from the matrix coming to occupy all the voids and pores.
This can be explained by the presence of wheat straw fibers (WSF) in the mixture (soil + cement), causing the grain rearrangement to be more difficult.
The decrease in (CS) is due to the increase in the number of voids inside the blocks not stabilized with the cement due to the detachment of the straw fibers (WSF) from the stabilized soil matrix of dry blocks.

A number of powder mixtures of transition metal with Si-based non-oxide ceramics (SiC or Si3N4) were uniaxially pressed into pellets.
In such a case, instead of applying phenomenological theories, one has to explain an infinite number of situations, all for their own.
There are, however, a number of “exceptions” where other factors have also to be taken into account.
The behaviour of Carbon formed in the reaction zone between Platinum and HIPSiC (with grain size of about 1 μm) probably reflects the “averaging effect” since SiC-grains within the ceramic material are small and oriented randomly.
From an analytical point of view, a number of difficulties is experienced in Auger- and EPMA of samples containing Titanium and Nitrogen.

Shingle with 10-mm maximum particle size and river sand with 2-mm maximum grain size was used as coarse and fine aggregates, respectively.
During the test, notes were taken to record the number of blows required to initiate the first visible crack and the number of blows required to cause ultimate failure of a HFRC panel.
Every HFRC panel initiated the first visible crack after certain number of blows and followed by more blows to reach ultimate failure.
Number of blows required to initiate cracking and subsequently to cause ultimate failure is useful in determining overall pre- and post-cracking behaviour of HFRC panels under impact loading, which are presented in Table 2 in which the number of blows is the average from results of four panels with same testing parameters.
These numbers turned into 219% and 45% in case of 20 mm-long fibres.

However, when an inert gas was introduced, the flame was being enriched with fuel and the number of hydroxyl radicals decreased, and the additional introduction of an inhibitor led to a more effective reduction of hydroxyl radicals in the flame.
Thus, a significant number of fire-fighting systems equipped with halon 1301 or halon 2402, which are ozone-depleting substances and subject to the Montreal Protocol are operated at gas transportation enterprises.

Though large number of ion-exchange materials of hetropolyacid salt based tin(IV)[11-14], Cerium(IV)[15] titanium(IV)[16]and zirconium(IV)[17,18] with polyaniline have been mentioned in literature, their ion exchange property are not completely understood[19].
The SEM images give an idea that the composite materials consist of irregular heterogeneous surface showing high surface area [40] and huge number of agglomerates.
In complex impedance plane, all effects viz., grain, grain boundary and grain-electrode effects appear as a semicircle, whose centres lie on a line below the real axis.
As the magnitude of the conductivity is determined by the number of charge carriers (polarons and bipolarons) [45, 46] available for conduction and the rate at which they move, the increase in conductance with temperature is due to increase in charge carrier concentration.

Magnetic properties of soft magnetic composites and parts made of them depend on a number of factors.
Source: own work based on [12, 15] Bertotti’s theory has been adopted to SMCs in a number of papers [15-20].
Bertotti has suggested a number of more complicated dependencies for different classes of soft magnetic materials [13].
This effect may be due to a different number of data points used in fitting of three curves.
This approach has been followed in Refs. [19, 20], where a correction factor is introduced in order to replace the true microstructure of the SMC with a homogenized medium that has uniform rectangular grains.

According to the Texaco gasification of grain size distribution and some rules, we had prepared the water-coke slurry, then we tested its properties of viscosity, flowability, syneresis rate.
When the wave number was 2927.5 cm-1,it was the stretching vibration band of C-H from methylene.
When the wave number was 1641cm-1, it was the stretching vibration band of double bond C=C.
When the wave number was 1434cm-1, it was the bending vibration bands of C-H from methyl.
The absorption peak when the wave number was 1732.8cm-1,1227.5 cm-1 had increased obviously.

Finally, the relation between the reduction and the number of rolling passes was discussed.

Grain curves of aggregates used 2.2 Mix proportion and sample preparation.
This experimental work was carried out in two groups with a total number of ten concrete mixtures to achieve the objectives of this work.
It is of significance to note that the compressive strength has decreased because the substitute aggregate grains are softer, more porous, and have more voids than the natural aggregate, rendering them weaker and more brittle than their natural counterpart.
Despite the compatibility of binary aggregates (coarse and fine) in the recycled concrete mixtures produced, the permeability of concrete was dependent on the variables of the type of aggregate, its grain shape, and its physical and mechanical properties.
Therefore, disability-adjusted life years (DALYs) were determined based on the conversion factor mentioned in Section 2.3.6, where DALYs express the number of years lost due to lack of health, disability, or premature death.

This cond of stressed state promotes to essential increase plasticity resource of the material, and alternant deformatuin accumulation, while some numbers of processing cycles of alternant moovement is running, leads to grain size refinement and gradient gradient submicro- and nanostructure formation out of inner surface and as followed – gradient hardening character.
On the experiments carryed out [32 – 34] as a variable parameters the number of processing cycles n and axial step S was selected.
Here S is the equipment axial step, n is a number of processing cycles, hв is a penetration depth of deformation rib.
At the same time established that than the maximum number of processing cycles for selected parameters reached the specimen material is damaging (Fig. 9).
It’s established that on maximum hardening degree parameter value the number of processing cycles has more influence that equipment axial step, but on maximum thickness of hardened layer parameter the equipment axial step value has more influence than number of processng cycles.
