The factors such as increasing of growing population, daily and industrial activities will lead to these phenomena.
The results demonstrated that, in terms of physical and mechanical properties, CB Brick (2.5%) at 1°C/min improved the most and leached low heavy metals.
According to the previous results of physical and mechanical properties, TCLP was conducted because CB Brick contains high heavy metals compared to Clay Brick (0% CBs).
In this stage, by comparing with different percentages of CBs, CB Brick (2.5%) at 1°C/min yields the optimal performance in terms of physical and mechanical properties of manufactured brick, and then it was selected to be tested for IAQ.

Finally, the 7150 Aluminum alloy treated with RRA technique has good mechanical properties.
Although it only goes through a short time from being researched to being applied, the excellent properties of aluminum make the aluminum alloy once researched and developed be recognized and widely used.
The restricting factors causing the block for aluminum production and development in China mainly include the aspects below: 1) From the view of quantity, the aluminum ore reserve in China is abundant.
According to the different structural properties of materials, it can use rigid elastic plastic finite element method and plastic, visco plastic finite element method etc. in the specific work.
Conclusion In summary, this paper mainly research and discuss the properties of 7150 Aluminum Alloy shown in multipass hot-rolling process and the related simulation data, and analyzes the displayed experimental data.

The surface properties can be altered and improved by developing coating in conventional steels that are used for impellers.
The longevity of associated impellers directly correlates with their surface properties [1-2].
The main factors influencing cavitation erosion are the pressure drop below vapor pressure and the distance between the material's surface and the bubble formation sites.

Indeed, mortars rheological properties are extremely important since several factors, related with placement, consolidation, durability and strength depend on the flow properties of the mortar paste.
In this work, the effect of ageing time on the rheological properties of fresh aerial lime-based mortars was investigated.
However, they were gradually replaced by mortars based on Portland cement due to the uniformity of fabrication and their better mechanical properties.
In mortars is now also common to use admixtures in order to improve or adjust some properties (in fresh and hardened state).
Ageing promotes the water intake, creating inter-particle films that make the mortar more cohesive but with better flow properties.

To control the properties of materials requires a new method, the database of comprehensive evaluation of physical and chemical factors of the technological chain of energy efficiency of the process of ensuring coherent combining of atoms.
Structural organization and compound properties are firstly determined by the type of chemical bonds between the elements of the interface.
The dominance of metallicity degree over the covalence provides less energy of the electrons with the atomic cores and their greater delocalization and mobility, in other words, greater probability of the wave properties, quantum-mechanical effects and increased reactivity developments, such as particle coagulation and chemical reactants.
It is the basis for expansion in the region pairing information about the mechanical properties of the density and temperature.
