The factors influencing the formation of efflorescence of construction materials are studied insufficiently in terms of chemical and physical processes that occur during the operation of construction products.
Efflorescence may accumulate under some less permeable decorative paint layers and cause their peeling from the surface of a building structure, its decorative properties being completely lost.
The factors influencing the formation of efflorescence of construction materials given in technical literature [2-5] are connected with the increased solubility of the ingredients of construction materials.
Efflorescence may accumulate under some less permeable decorative paint layers and cause their peeling from the surface of a building structure, its decorative properties being completely lost.
Efflorescence in vibropressed pavers does not affect the mechanical properties and the structure of set cement in pavers, as this efflorescence in the second year of operation does not resume due to the carbonation of calcium hydroxide and reforming it into an insoluble calcium carbonate in the structure of set cement.

Corrosion behavior, mechanical properties, creep resistance, hardening/baking behavior, additive manufacturing suitability are among the studied themes.
All these properties are strictly linked to the microstructure of the material.
Moreover, the alloy exhibited better mechanical properties at short time creep, and worse mechanical properties at long time creep than the same alloy with higher Ag content [3].
Several factors are known to influence creep behavior of aluminum alloys: grain size, texture, coarse and fine precipitates, heat treatment.
The first considered factors are grain size and shape factor.

Thus, twenty different SCC mixes were designed with varying input factor combinations (FA: 0–40%, LA: 0-50%, and PET fibre: 0–2%) and tested for six responses (rheological properties, namely slump flow, V-funnel time, and L-Box; and mechanical properties, namely compressive, split-tensile, and flexural strengths test).
The materials used as the RSM input factors.
It can also be seen that FA, LA, and PET are the significant variables affecting the slump flow values.

Mineral Component and Engineering Properties Mineral component.
Strength and deformation characteristics of the filling are important factor affecting the stability of highway roadbed, and they are also significant parameters in highway design.
These are possible factors to affect rock strength.
There are two factors contributing to this result.
On the other hand, softening and wet-chemical properties of mineral component are the internal factors causing the deformation.

Metal matrix composites (MMCs) have been found to possess tremendous prospective engineering applications that require materials offering a combination of lightweight with considerably enhanced mechanical and physical properties.
Introduction Metal matrix composites (MMCs) derive their excellent mechanical properties from the combination of a hard reinforcement phase such as silicon carbide (SiC) and a ductile matrix material such as aluminum.
Although many factors affect the tool wear of a CBN and PCD inserts, machining parameters such as cutting speed, feed rate depth of cut, and work piece properties have a significant influence on the tool wear for a given machine tool and work piece setup.
The tool wear is less on PCD tool insert because of its superior material properties.

Reaction rate is mainly affected by reaction temperature, material uniformity, mold channel scale etc, the influence of such factors affected the quality of the moldings and material properties[2].
Besides above, there are also many influence factors of vacuum casting parts, such as operating time, curing time, ratio of resin, curing temperature, etc, arranged in the descending order of importance
(4) Ratio of resin Different ratio of resin will change the mechanical properties of the parts, when the ratio is not correct, mechanical properties will be changed such as bending strength and bending modulus of elasticity, etc
Table 1 and Table 2 showed the physical properties and mechanical properties under 23℃ of UP 4280 respectively.
Blue line in picture fig.5b shows weld mark, the weld mark can have influence on the mechanical properties and appearance of the product, but materials of vacuum casting have a longer solidification time, the influence of weld mark for the material physical property is week, it can only as a reference.

These results in a significant decrease in material properties.
Its matrix strength and pore morphology are the main factors affecting the strength of the material.
Thus the stress concentration will be smaller, and the materials will present greater mechanical properties.
All these prove that excessive addition of sodium silicate will deposit into the pores, affect the structure of the pores and cause a large number of perforation phenomenon, thus seriously reducing the mechanical properties of the material. 4.
In these crystalline phases, the short-rod like 5·1·8 phases as the strength phase has the strongest mechanical properties.

This cermets type of WC-Co composite material is also called hard metal and display relatively superior properties related to the mechanical strength, wear resistance, impact energy, hardness and fracture toughness.
However, the high cast associated with geopolitical conflicts and environmental issues in its mining are factors that increasingly limit the use of this metal [3 - 5].
As can be seen in Table 3, the increased pressure promoted a slight improvement in the properties of composites.
