The observation results were presented as cross-section data: , (2) where the column indicates the proportion of limestone in the mass of cement, is the fraction of diopside, n is the number of observation, , is the strength obtained in i observation.
Diopside has the highest hardness (7 on the Mohs scale) out of the considered silicate materials number that is, the highest value of the elasticity modulus.
According to a number of scientists’ researchers [12, 19, 20], it is possible to bind a significant part of portlandite released during the hydrolysis of three-calcium silicate in a hardening hardened cement paste with the active interaction of limestone, calcium hydroxide, hydroxides and carbonates of alkali metals.

It causes the acceleration of powder grains and creates a perfect distribution of polymer matrix on fiber substrate.
A saturation stage is reached as the number of fiber fragments becomes constant during elongation.
Measured fragment lengths Li are ranked in ascending order from shortest (i = 1) to longest (i = n, where n is the total number of fragments).
In abscissa the quantity i/n was considered, where i is the rank and n is the number of fiber fragments [11].

Sample surfaces underwent a polishing procedure with Ce2O3, Al2O3 and diamond suspension down to grain diameters of 0.25 µm which were controlled carefully by light microscopy and scanning electron microscopy to ensure that the influence of the surface preparation on the results of the LIDT measurements was negligible.
For a given laser fluence F0 and number of pulses per spot, ten test sites on the samples were illuminated.
For a given laser fluence, the number of damaged samples was counted.
Fiber type numbers indicate core-cladding diameters.

Also, with an increase in the number of rare-earth metals in an aluminum alloy, the number and size of intermetallic compounds increases with the classical methods of preparing the ingot, which negatively affects all the properties of the wire.
In the process of high-quality rolling and drawing of a bar Ø5 mm, obtained by the CRE method, there is no change in the size and shape of the phases, their location and number, the vast majority of particles have a size not exceeding 1 μm.
The grain structure of the wire was not evaluated due to the fact that due to the small cross section it was not possible to deposit an oxide film.

The present study provides the results of a number of laboratory tests carried out on the soil collected at Grazzanise airport as well as CBR indexes measured in-situ in order to corroborate the results obtained in the laboratory.
To this end, a number of in situ and laboratory tests were carried out on the soils samples collected at Grazzanise military airport in order to conduct testing for sieve analysis with pre-washing, Atterberg limits, soil density and moisture, soil classification and CBR on lime-stabilized soil samples.
Soil Classification [4] Nomenclature Grain size, diameter d [mm] Percent passing [%] Clay d < 0,002 2,0 Silt 0,002 < d < 0,06 94,3 Sand 0,06 < d < 2 2,7 Gravel 2 < d < 60 1,0 Cobble d > 60 0,0 NOTE: 1mm = 0,04 in Hydrated lime was used during the first laboratory test.
A number of checks were performed on homogeneity and moisture of the mixture, as well as on the current depth of the mixing machine, at the end of mixing.

These factors include particle size of the metal powder [6], [7], compact’s size and shape complexity [8], type and number of binder components [9].
Table 1 shows the debinding and sintering variables and the number of levels chosen for the experiments.
(1) Where, Yij is the amount of score for the rate of mass loss and n is the number of times the rate of mass loss was measured.
A lamellar alpha phase (white) and a beta phase along the grain boundaries (grey) are observed on the microstructure.

There is also a number of different types of ceramic composite materials where a toughening effect is achieved by application of whiskers, short and long fibres, particles, phase transformation toughening, using laminated and micro-laminated structures and/or their combination achieving so-called hybrid composites.
Results from these experiments are summarised in Fig. 5 together with average data (represented by full line) obtained using the standard three point bend test on CNB bar specimens. 0 1 2 3 4 5 6 7 8 9 10 11 Sequence number 0 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 1 1.1 1.2 1.3 Fracture toughness [MPa.m1/2] Soda lime glass chevron notch in tension CNB 3x4 S=16 mm Fig. 5 Comparison of fracture toughness obtained using eccentric tension and three-point bending on notched specimens prepared from soda-lime glass.
This strong dependence of fracture properties on number of reinforcing fibres in the process zone cannot be explained only by weakening of the apparent interface due to presence of fibre matrix interface.
The regions close to the fibre exhibit significant grain growth during sintering which leads to lower fracture resistance.

The results show that this method improves the grinding efficiency and produces the powder with real nanometer grain structure.
Preparation of Silver-Series Nano-Antibacterial Materials by Biological Method A large number of studies have shown that the AgNPs synthesized by chemical method is expensive, and the reductants, surface modifiers and stabilizers used in the synthesis process pollute the environment.
A large number of scholars have shown that bacteria can be used to prepare AgNPs.
Fungi can secrete a large number of enzymes and are easy to grow on various media, so they are considered to be a suitable choice for biosynthesis of AgNPs.

(4) Requirements of coarse aggregate grain size is not greater than 30mm to ensure the pouring quality.
One should increase the vibration time and vibrating point number until around the box without bubbles，Vibrator should avoid touching the box
We suppose a number of columns for n boxes of a pouring area.
Secondly, the new method does not increase the number of workers.

It must be noticed that the reported micrographs refer to gravity cast samples; a real semisolid process is characterized by the injection of the alloy into the die, which produces high shear stresses in the liquid that strongly affects the solidification, enhancing shape and number of globules.
According to atomic number sequence, Al-rich matrix appears as dark phase, while the Sn-rich phase is light.
Also AlFeCu intermetallics could be observed at the grain boundary of the primary phase, rejected during solidification on the solid front and, thus, formed in the last freezing liquid (spectrum 1).
In Fig. 4 the evolution of friction coefficient as a function of the number of cycles is shown.
