The fiber cloth has good tensile properties and toughness which plays a role in strengthening the concrete [9-11].
The Main Factors which Play a Major Role in the Control of the Cracks for the Concrete Structure For ordinary concrete structures, the factors that play a controlling role in structural fractures are the cohesive force between the reinforcement and the concrete.
The main factors influencing this cohesive force include: Joint Surface Treatment Method.
The adhesive force is not only related to the physical properties of the binder, but also with the concrete treatment method of the old concrete, the construction method of the adhesive and the selection for high quality adhesive.
Without considering other factors, the crack width will be 38% of the principle, the cracks are denser and finer, meeting the engineering requirements.

However, several intrinsic factors such as poor dimensional stability, reduction in electrical conductivity with time, interfacial instability, low porosity and poor thermal stability lead to high cell resistance, internal short circuits which are deleterious in terms of poor performance and reliability, especially affect the safety of the device[2].
The porosity is an important factor in determining the ion transport properties of the electrolyte.
Thermal shrinkage of the separator is another important concern affecting not only the Li-ion capacitor performance but also its safety.

That makes it possible to increase its physical, mechanical, organoleptic and other properties [3].
This makes a significant contribution to the energy of the system and affects a number of factors: melting point, solubility, shift in chemical equilibrium, etc. [5].
It causes deterioration of mechanical properties [8,11].
They allow in a wide range to vary the properties of the binder, depending on its purpose.
Our research has established that the stabilization of CNTs is provided by electrostatic, adsorption-solvation, and structural-mechanical factors [17].

Introduction
Diamond was one of the ideal materials which were suitable for industrial applications because of
its unique combination of excellent physical properties, such as high hardness, good thermal
conductivity, outstanding wear and chemical resistance.
Concerning the applications, where low friction coefficient and great surface morphology were demanded, various techniques for depositing high quality diamond films of well defined material properties were pursued by numerous research groups.
In addition, the material properties of filament, cemented carbides substrate and workbench under the working condition have been shown in Table1 respectively.
Based on the AUX12 method for radiation, SHELL57 element should be specified on radiating surfaces to calculate the form factors of the radiating system.
The arrangement in the HFCVD reactor was the key factor influencing the growth rate and quality of diamond films.

However, recently, research and industrial applications, using the specific material properties obtained from pore morphology, such as optics, acoustics, etc., are actively performed.
Recently, there has also been research regarding the changes of the electrical properties.
Batch process is used often in research experiments, since it is easy to control the process factors.
The factors of the saturation process that affect the resultant porosity are the blowing agent, saturation pressure, saturation time, and saturation temperature, while the foaming process factors are the foaming temperature and foaming time.
To control the foaming ratio, this experiment only varied the foaming temperature, while keeping all other factors constant.

However, a sustainable concrete is not easy to define; there are many factors that may change its components during its life span.
The heat loss through the kiln structure is an important factor beside the cement kiln technology which affects directly the amount of heat energy to produce the clinker. 1 ton of clinker produced = 3~7 G.
As defined by the Italian technical standards for construction reference DM 14.01.2008 [17], concrete and/or structure durability is defined by the retention of its physical and mechanical properties which are essentials to maintain the lifespan safety of the structure.
Concrete durability can be achieved through resisting weathering and any other exterior degradation factors by maintaining its characteristic performance.
ü The exposure factors affecting the concrete durability.

Mechanical properties of materials such as Young’s modulus yield and tensile strengths depend on temperature.
The effect of high temperature on mechanical properties is linked to some micro structural transformations of the material due to complex physical processes.
Fatigue properties are affected by temperature.
In practice, one should also consider variations of material properties due to temperature which will have their proper influence on TMF.
The effect due to material properties as they can be affected by temperature was not investigated.
