In fact, the void is inevitable with the current state of materials and construction method.
Classification of the Void The void of Concrete Filled Steel Tube is generally divided into two categories, the first category is called void caused by the non-compacting, and defined as the void caused by the holes due to the defects of quality, materials, constructions and technology between the core concrete and steel pipe.
Its fundamental principle is to make the defects such as micro-cracks and pores of the concrete least through reducing the particle size of raw materials, using reasonable gradation to increase the packing density of the material, then to obtain the largest carrying capacity and excellent durability determined by the material.
The raw materials include sands, high efficiency water reducing agent, short-thin steel fiber, etc.

XRD showed that the nanometer materials and textile wall fabrics were a good combination.
Thus, it can be determined if the nanometer materials and textile wall fabrics have good combinations.
According to Bragg's law, it is certain that the corresponding materials of the diffraction peak 1 to 7 were TiO2.
According to Bragg's law, it means that the corresponding materials of the diffraction peak 1 to 9 are TiO2 and the corresponding materials of the diffraction valley 10 to 16 are copper sulfate.
XRD showed that the nanometer materials and textile wall fabrics were a good combination.

Like other metal materials the failure of magnesium alloy component is frequently caused by fatigue, so more and more attention were paid on the fatigue properties of magnesium alloy by materials researchers and engineering designer [4,5].

Except for the demand for materials and culture, people also require the nice and sustainable development survival environment in the present age.
Conclusion When resource and environment become the bottleneck of economic development and the traditional materials transforming in the direction of single flow couldn't go on, we should develop circular economy to realize the sustainable development of human being.
To develop circular economy must change the materials transforming flow of people's production activities, and alter to circular flow from traditional single flow.
To realize the reformation of materials transforming flow need not only technical innovation but also the reform of economic relationship and economic benefit regulation.

The top layer of the ground surface experience work hardening process, hence the hardness is higher than the average hardness of the workpiece materials.
However, the material beneath the top layer is softer as a result of over-aging of the materials.
