capacity and fatigue properties of military bridge, effectively reduces weight of bridge span structure, and reduces by above 23% compare with that of traditional steel bridge.
Material selection should consider not only the material properties, but it is more important to consider manufacturing methods, connection technology, cost performance and other factors of material.
Considering the ecological and environmental factors, material components that can be reused (such as basalt fiber and thermoplastic matrix) will be widely used in development of new lightweight material of crossing-river and military bridge equipment.
Any structural material must be able to withstand the mechanical load.
As various requirements must be satisfied, to evaluate material is necessary so as to determine priority of material properties.

Soilcement has high soundproofing properties because it perfectly absorbs noise.
Fly ash - finely dispersed dust with hydraulic and (or) pozzolanic properties.
These factors cause constant interest in this material and a constant desire for its improvement on the part of scientists and practitioners [9].

The cocktail effect suggests that the properties in HEAs not only come from the basic properties of elements by the rule of mixture, but also from the mutual interactions among all the elements.
Extensive investigations had been carried out in the past decade on improving the physical and mechanical properties of HEAs, along with some specific focus on thermodynamics and precipitation kinetics of the second phase.
These two factors would create disturbance in configurational space and consequently reduce the configurational entropy.

Experiments show that the injection pressure and air/liquid ratio (ALR) are the major factors impacting the atomization stability, and the flow coefficient of the nozzle ranged in 0.1-0.15.
The location and area ratio of the aerator holes, final discharge orifice diameter, the length to diameter ratio play important roles on the performance of effervescent atomizer, and the spray behavior, including the liquid flow rate, the velocity distribution of the droplets and the spray angle, are affected by a series of factors such as the liquid and gas physical properties, the operating parameters, including the injection pressure drop and GLR.

Energy absorption properties of basalt fiber reinforced concrete.

Micromechanical properties in micro area showed considerable decrease and creep resistance was significantly higher at middle dose.
As a result, the solubility of the polymer in solvent increases and the mechanical properties of the polymer deteriorate.
However, some experimental data have shown that PMMA transforms from a positive resist into a negative resist and the mechanical properties improve rather than degrade when it is irradiated with a high-influence ion beam.
However, mechanical properties such as hardness and elastic modulus of the polymer were dramatically deteriorated after a high-dose electron irradiation.
Our experimental results show that total radiation dose is a key factor to determine property changes in the electron-irradiated polymer.
