This research is focused on the study of improvement on physical and mechanical properties of cement mixed clay.
Terashi summarized the various factors affecting strength of cemented clay into four general categories: characteristics of stabilizing agent; characteristics and condition of soils; mixing conditions; and curing conditions [10].
The general properties of soil used in this research before cement mixing are summarized in table (Table 1).
General properties of Kathmandu clay.
The trend in the variation of these properties is not linear as shown in figure (Fig. 2).

The resistance factors showed that the recycled material is potential as insulation, barrier, or roofing tile.
Food packaging manufacturing industry considered gas and water vapor barrier property [4] of a material as primary factors to ensure the shelf-life of the food products [5].

Conclusion Recycling aluminates impregnated with small ratio by weight of OC increased the thermo-physico-mechanical properties of the new material.

However, final properties of PLA composites reinforced with natural fibers are influenced by several factors, both in fiber as well as matrix terms.
From the point of view of a fiber, the degree of filling, fiber length, fiber morphology, fiber orientation and fiber distribution, all these factors have the effect.
Results and Discussion The mechanical properties are summarized in Table 3.
Experimental results of the mechanical properties of the biocomposite materials confirmed that mechanical properties are not only dependent on the type of fabric (woven, knitted, nonwoven), but also on the structure and fabric density.
Furthermore, mechanical properties depend on the orientation of the hierarchical fabric in the biocomposite.

In addition, the factors affect wear resistance of the material also include the production process and the heat treatment process, for example, casting coarse grain abrasion is less than fine grain.
It has closely connection between the tribology properties, surface properties, and other factors.
Lubricant has a certain influence on the friction properties of friction pair.
In addition, it also should take the temperature and environmental factors into account.
For example, for bucket wheel excavator, a major factor affecting their life span are the angle of the bucket teeth mounted on bucket lips and the specific shape of bucket teeth.

The results indicate that the main factors affecting the bulge height are the thickness of sheet metal and diameter of punch-die within a certain range.
But the mechanical properties of product are poor by casting, material varieties are limited by casting die.
The second method is to use the punching process after forging operation, and the mechanical properties of parts are fine.
That to say, the main factors of affecting the tubular bulge height are the diameter of punch-die and the thickness of sheet metal.
The main factors affecting the bulge height are the thickness of sheet metal and diameter of punch-die within a certain range.

These factors made FSW uncompetitive, especially in the applications where robotics are currently used.
Results and discussion Macro-mechanical properties.
Also for AA5754-O, the mechanical properties of robotic FSWed joints are mainly affected by the welding speed, in particular, as w increases up to 60 mm/min.

This paper discusses the property of the air-jet spinning and the main structural factors affecting air-jet spinning yarn strength.
Introduction Traditionally, air-jet spinning yarn is given false twist by the revolution of pressed air stream, and it turns at a very high speed that is impossible with mechanical twisters.
Due to the distance between two nozzles intake and the relevant jet orifices, i.e. jet orifices position of two nozzles, affect air-jet spinning yarn strength individually, and interaction between them also affect yarn strength.
To evaluate individual and interaction effects between jet orifices position of two nozzles and yarn strength, we choose jet orifices position of two nozzles as experiment factor and adopt the two factors rotary experiment design.
The two-factor testing level coding is shown in Table 1, and the structure matrix table of two-factor second rotary experiment design is shown in Table 2.

These three factors had a great relationship with the contents of SB powder, Nitric acid and water.
Nitric acid is chosen as the peptizing agent, the content of which is one of the most important factors of forming condition.
Fig. 6 shows how the content of nitrate affects the mechanical strength.
The first one is the growth of surface properties, such as the pore volume and the number of acid centers.

Microalloying in high strength steels causes the generation of some phases in the matrix able to increase the mechanical properties of the joint.
The effect of second peak temperature on hardness and microstructure is reported, especially focusing on residual austenite and precipitation, as main element affecting the fatigue behavior.
The proper balance between mechanical properties in HSLA steels depends on the thermal cycles employed during welding, which can result in low toughness behaviour in the heat-affected zone (HAZ).

China Keywords: porous ceramics; mechanical properties; fabricated process Abstract.
In this paper, the mechanical properties of porous Si3N4/SiC composite prepared by different forming method (uniaxial pressing and gel-casting) were compared.
But up to now, the mechanical properties of this kind of material is low because of the high porosity, which will limit the application of them.
Mechanical properties.
The forming method was also an important factor to affect the flexural strength and porosity.
