The paper presents an overview of “lessons learned” with detailed information on factors affecting the rate of chloride ingress.
This paper presents an overview of “lessons learned” with detailed information on factors affecting the rate of chloride ingress and the performance of concrete containing supplementary cementing materials (SCM) such as fly ash, ground granulated blastfurnace slag (hereinafter referred to as slag) and silica fume.
Examination of the concrete after exposure revealed that the air-void spacing factors were good (generally ≤ 230 microns) and that there was no evidence of micro-cracking related to freeze-thaw damage.
This indicates that damage was, generally, restricted to the surface and this explains why the bulk properties of the concrete, as measured by UPV and RDM, were unaffected.

In recent years, many researchers at home and abroad make a number of experiments and theoretical analysis on structural performance of steel fiber reinforced shotconcrete[1-6].Among them, Professor Du Guoping researches the enhancement mechanism of steel fiber reinforced shotconcrete from the viewpoint of its mechanical property [7] ; Professor Liu Xin carried out experimental study of basic mechanical properties of steel fiber reinforced shotconcrete from the viewpoint of this actual work [8]; But the research about the influence on concrete micro pore structure under different construction technology is still small.
According to the material constitutive relationship, concrete as a porous system materials, any of its properties are determined by their composition and microstructure.
Steel fiber reinforced shotconcrete (PSC) and model steel fiber reinforced concrete (MSC),that two different kinds of construction technology make much different on concrete forming and mechanical properties.In order to make the test to correspond with realistic engineering situations, all used specimens are made at the scene.After 2 days of conserve,dumoulded and sent to the laboratory for standard conserve.
of concrete[10-12], other properties of pore, such as pore size, pore size distribution, pore shape and orientation also affect the strength of concrete [13].
(3) Pore structure, pore size distribution, density and other factors which affect the durability of sprayed steel fiber concrete are less than model steel fiber reinforced concrete .

In machining operations, the surface roughness generated is influenced by an enormous set of factors.
But it is not an easy task due to the dependent nature of the surface roughness formation mechanism and the numerous uncontrollable factors influencing it.
The set of factors that influence the surface roughness can be observed in a fishbone diagram (Fig. 1) that considers: machining parameters such as process kinematics, cooling fluid, stepover, depth of cut, tool angle, feed rate and cutting speed; the cutting tool properties such as the tool material, runout errors, tool shape and nose radius; the workpiece properties such as the length, diameter and hardness; and the cutting phenomena such as the cutting force variation, friction in the cutting zone, chip formation, vibrations and accelerations.
Surface properties play a decisive role on the properties and characteristics of the finished piece.
It is determined by material properties and process that formed the surface. 2.

Copper and magnesium strengthen the alloy matrix and improve the mechanical properties.
Heat treatment is one of the major factors used to enhance the mechanical properties of heat-treatable Al-Si alloys, through an optimization of both solution and aging heat treatment given to these alloys.
An understanding of these factors and exploring the heat treatment differences between T5 and T6 for 319 alloys would help in selecting the metallurgical conditions required to achieve the optimum mechanical properties.
The 2k factorial design [10] is the ideal choice for providing information on the main effect and interaction of metallurgical factors on the mechanical properties of the heat-treated alloys.

When metals that present bcc crystalline structure receive the addition of interstitial atoms as oxygen, nitrogen, hydrogen and carbon, they undergo significant changes in their physical properties because they are able to dissolve great amounts of those interstitial elements, and thus form solid solutions.
With the addition of substitutional solute, interactions between the two types of solutes (substitutional and interstitial) were observed, considering that the random distribution of the interstitial atoms was affected by the presence of substitutional atoms.
Interstitial diffusion coefficients, pre-exponential factors and activation energies were calculated for oxygen in this alloy.
When metals that have bcc structure receive the addition of interstitial atoms such as oxygen, nitrogen, hydrogen and carbon, they suffer significant changes in their physical properties because they are able to dissolve great amounts of those elements, thus forming solid solutions.

Previous studies demonstrated that the tribological properties of the DLC films could be affected by a variety of deposition methods, parameters and test conditions.
Therefore, the establishment of relationship between deposition factors and chemical bonding properties is of great importance to the application of DLC films[12,13].
The influence of the substrate bias voltage on the structural, mechanical and tribological properties of the films is discussed.

This paper presents a summary of research achievements on fire-resistance behavior of HPC in the past 10 years including the mechanical behavior degradation, analysis of spalling mechanism, effect of various types of fiber and other factors influencing the post-fire properties of HPC material as well as structural behavior of HPC elements.
Microstructure of HPC under elevated temperatures Physical and chemical reaction The evolution of microstructure of HPC can surely affect the mechanical properties of the structure when heated [13].
Sullivan [45] examined how the explosive spalling was affected by several factors in order to obtain a clear understanding of the deterioration of HPC beam in flexure during fire exposure.
The deterioration of mechanical properties of the entire HPC frame structure is found to be not as serious as that of the materials.
