Hardness number of NBR with various fillers
From the data above it can be seen that each alloy gives a different effect.
Increasing hardness is caused by the presence of an optimum amount of reinforcing filler, which will increase the hardness, wherein the strengthening effect of the filler is determined by particle size, surface condition, shape, grain fineness and even distribution.

And those and other materials have both a number of advantages and disadvantages.
To determine the paving device cost made of asphalt concrete, the following parameters were taken into account: · excavation for the device base of sand and gravel under the road surface; · device base of sand with a thickness of 15 cm, followed by compaction; · device base of crushed stone with a thickness of 20 cm, followed by compaction; · laying of asphalt concrete from cast fine-grained asphalt concrete mix 3 cm thick; · bitumen emulsion coating treatment; The building materials cost To determine the cost of the pavement device made of concrete paving slabs, the following were taken into account: · excavation for the device base of sand and gravel under the road surface; · device base of sand with a thickness of 15 cm, followed by compaction; · device base of crushed stone with a thickness of 20 cm, followed by compaction; · laying of paving slabs of gray color of the 7P.8 brand with a size of 200x100x80; The building materials cost.

Crushed cullet had a modulus of particle size MK = 0.945; true density - 2,435g/cm3; bulk density - 1.313g/cm3; the content of grains 5 .... 10 mm - not more than 1.5%, the content of small particles (dust) - 4%.
However, artificial glass composition is a complex system containing a number of oxides, such as Al2O3, BaO, CaO, MgO; Kinescope glasses also contain up to 30% lead oxide and up to 13% barium oxide.

It can be observed that a number of coarse second phase particles distribute along the extruding direction.
There are no small particles precipitate observed inside the grains, it might be attributed to the samples were quenched into the water quickly after solution treatments.

Result and Discussion
A number of samples with different thicknesses of YSZ and CGO layers were fabricated in order to study and analyze the electrochemical performance.
This is due to the fact that sintering at high temperature improves the contact between grains within cathode as well as the contact between cathode and electrolyte.

In order to gain optimal performance of PE removal from the brown part, the S/N ratio of the larger-the-better was used for the experiment which the formula is defined as:
S/N= -10log(1nj=1n1y2ij) (1)
where n is the total number of shots for each trial and Yij is the amount of score for the brown part density.
It is similar with previous study done by Obasi et al. [13] where he found that heating rate factor appears to be critical and influenced final density and grain size.

Dried sludge is yellow-brown, its surface area (by Brunauer-Emmett-Teller method) is 240 m2/g that corresponds to the average grain size of 10 nm.
The suggested method of the pigment production has a number of economic and engineering advantages that allowed the authors to get the invention patent ‘Production method for iron-oхide pigments’ (N 2471836) and the utility model patent ‘A unit for the production of iron-oxide pigments from sewage sludge’ (N 114683) [4, 5].

On the contrast, with liquid metal cooling (LMC) technique, the much higher thermal gradient can be obtained during solidification, resulting in the refined structures, reduced grain defects and superior mechanical properties [5].
Average primary dendrite arm spacing, λ1, was calculated by the area counting method on the transverse sections with the equation λ1=(A/N)0.5, where A was the area of selected region, N was the average number of primary dendrite in measured area.

On the model, the lines in the direction of the x-axis were marked with the numbers 1-35, the lines marked A – D‘ lead in the direction of the y-axis.
Nests created either by insufficient compaction or by other faulty production procedures also contain air gaps between the aggregate grains into which the cement laitance has not flowed.
