Results show that sulfur, used oil, calcium carbonate (CaCO3), reclaimed rubber, asphalt, diphenyl guanidine (DPG), mercaptobenzothiazole (MBT), and mercaptobenzothiazole disulfide (MBTS) are some of the significant ingredients of the formulation affecting the material properties of vulcanized NR.
Among the compounding ingredients, sulfur and used oil are the most influential and consistent factors which affect the swelling and tensile properties of vulcanized NR during water diffusion.
Solvent sorption and diffusion are therefore limiting factors of polymer end use applications because these processes change the mechanical properties and sometimes cause destruction in the polymer structure, resulting to material failure [2, 5-8].

Study of Affecting Factors on Porosity in Gel-casting Foam Qunfang Xiao, Xiaoshan Ning∗ and Ming Fu State Key Laboratory of Fine Ceramics and New Processing, Tsinghua University, Beijing 10084, China Keywords: Porous materials, Gel-casting foam, Mechanical stir, Reynolds number Abstract.
Effects of surfactant volume content and several stirring factors on porosity are studied in this paper.
Besides stir time and slurry viscosity, we found porosity is also affected by other factors.
From the bubble forming theory by mechanical stir, the affecting factors are considered to be surfactant, stirring factors and the properties of slurry.
This analysis tells us when foamed by mechanical stir, porosity is affected by surfactant, slurry properties and the stir factors.

This review focused on the mechanical and optical properties of experimental dental composites and the optical properties of commercial dental composites, including many factors that affect those properties—however, the mechanical properties of commercial dental composites being described as well to compare as the control.
Author Factors affect Control Properties tested Result Samuel et al. (2009) [44] Microstructure of silica in the form of mesoporous and silanized non- porous with 500 nm size.
One year after, the almost same person in the same group of the researcher (Salgado et al., 2014) carried out the optical properties of the experimental dental composites using 7 nm and 16 nm silica particles as filler and photoinitiator system as factors affect.
Filler volume affect the mechanical properties including hardness, higher filler volume incerased the mechanical properties [54].

The mechanical properties of sago waste were investigated to study the feasibility of using this sample as a raw material in particleboard manufacturing.
The mechanical properties have to be considered in order to support the use of the residues in industries application.
Mechanical properties of natural fibre composites are generally dependent on the properties of their components and the ratio of these components [6].
One of the factors affecting the particleboard performance is the particle size.
Besides, particle geometry (fibre length to thickness ratio) will be one of the factors that affect the impact strength.

Fig. 1 The factors affecting the durability of FRP reinforced concrete structures Factors affecting the durability of concrete material.Mehta [14] concluded the durability of concrete means the resistance of concrete towards weathering, chemical corrosion, abrasion or any other damage process.
The factors affecting the durability of FRP include chemical erosion, ultraviolet irradiation, freeze-thaw cycle, etc.
Factors affecting the durability of FRP reinforced concrete structure.FRP reinforced concrete structures normally consist of concrete, resin and fiber.
The factors affecting the durability of FRP reinforced concrete structure include wet-dry cycles, freeze-thaw cycles, chemical corrosion, etc. [5~7].
The mechanical properties of resin materials suffer great influence under conditions of wet-dry and ultraviolet.

The influence of various factors change on mechanical properties can be also analyzed by the intuitional analysis (Fig.4).
The results of intuitional analysis show that the affecting factors of RT TS are heat treatment regime, strain, forge temperature and status of billet according to priority (Figure 4).
The affecting factors of ductility for RT and elevated temperature 500ºC are strain, forge temperature, heat treatment regime and status of billet in sequence.
However, the affecting factors of TS at 500ºC are forge temperature, strain, status of billet and heat treatment regime in sequence.
