Compaction properties.
Flow properties.
Therefore the properties of aggregation over 2.0 mm is not within the granule properties measurement range.
A large angle of repose could create a reduction in the fill rate and thereby affecting the yield of granule [7].
In both granulations, particles’ movement was subjected to mechanical agitation and was less affected by gravity.

In this paper, the mechanical properties of this material which includes compressive strength, elastic modulus, flexural strength and bond strength are highlighted.
After years of service, however, the safety factor of the reinforced concrete slab can decrease due to a variety of factors, which in turn leads to an inadequate safety margin.

For this aim, Eshelby [4] based mean-field homogenization models provide a very cost-effective way of predicting the influence of the microstructure (thermo-mechanical properties of each phase; inclusions volume fraction, aspect ratio and orientation) on the overall properties.
Heterogeneities are classified in n families of identical inclusions according to their thermo-mechanical behaviors and their geometrical properties.
Homogenized mechanical properties.
The effective mechanical properties of mortar are weakened by the incorporated PCM particles.
The orientation of MCP particles in the mortar can affect slightly the mechanical and thermal properties.

Abstract: Experimental data are obtained by a series of fundamental mechanical properties experiments on autoclaved sand-lime brick masonry such as compressive strength experiment, shear strength experiment, bending tensile strength experiment, they provide the experiment evidence for writing Hunan province engineering construction local standard named "Technical specification for autoclaved sand-lime brick masonry building ".
Material properties Autoclaved sand- lime brick [Design strength respectively is MU10, MU15, MU20] Specimen preparation and test procedure follow the literatures [1, 2]. 200t pressure tester is used for pressure equipment.
Analysis of affecting factors of shear strength of autoclaved sand-lime brick masonry The full degree of the mortar joints directly affects masonry quality, thus affects the shear strength of along joint section of masonry [7].Combination of strength for mortar and block [8].
Because the same plate mortar is used in the second group and third group masonry in the article, the strength of the second group of specimens is the largest, after we exclude discrete factors of mortar, then the conclusion that there is an optimal combination of strength between mortar and block was drawn.

It is the chemical composition of elastomer that determines the mechanical properties of the elastomer; the paste process of strain gages will affect the parameters of the torque transmitter, such as linearity, measurement accuracy, hysteresis, repeatability etc.
Whether the recording apparatus to measure the accurate torque control directly affects the quality of the buckle.
Its mechanical properties are shown in Table 1.
For the paste process, the main consideration is the following factors: (1)Processing method of paste treated surface: Should study rust removal method of pasted surface because degreasing rust effect directly affects the co-attached degree of strain gauges and elastomers
(2) Elastomer is a key component of torque sensor, the chemical composition of elastomer directly determines the mechanical properties of the elastomer

Keywords: Anodizing; Al-Si alloy; High pressure diecasting; Microstructure; Surface mechanical properties.
Scratch and wear tests were also performed to investigate the surface mechanical properties after anodizing.
The presence of surface segregation prevents the thickening of the anodic layer, negatively affecting the surface wear resistance due to the reduced oxide thickness.
The limited thickness of the oxide layer formed on the grit-blasted substrate due to the presence of surface segregation negatively affects the surface mechanical properties, particularly the wear resistance.

The main factors affecting shape of graphite cast iron are the metallurgical structures and the section thicknesses.
Cast iron of different shapes of graphite particles directly affect its thermo-mechanical properties.
The nodular shape of these graphite particles such as in ductile cast iron improve its mechanical properties, on the other hand, when the shape of these graphite particles become elongated such as in flake graphite cast iron results in improving its thermal conductivity.
In between, the worm-like shape of these graphite particles such as in compacted graphite cast iron, make this type of cast iron to have thermo-mechanical properties in between those of ductile and flake graphite cast iron.
In the same matrix e.g. pearlitic matrix, the properties of graphite cast iron various based on the shape of graphite particles.

The Effect of Solid-To-Liquid Ratio and Temperature on Mechanical Properties of Kaolin Geopolymer Ceramics.
To form geopolymer materials with superior physical and mechanical properties, fly ash, metakaolin, rice husk ash, activated bentonite, clay, and red mud can be used [2].
However, there are many factors affecting the properties and characteristic for a geopolymer.
These ratios were chosen based on our previous work, as it allowed for optimal mechanical and thermal properties [11].
Both the S/L ratios and sintering temperature substantially affect the mechanical strength of the geopolymer ceramic samples.
