Though existing some property differences between recycled aggregate and natural aggregate according to the research of building waste, recycled aggregate could still be used for construction after being optimized with gelation, besides, these materials had a widely supply with simple processing technology and low production cost.
From the situation of China, the cost of land compensation and village relocation has become more and more due to land scarcity, and the cost of filling material and equipments will decrease with the development of science and technology, so it is a trend to fill mining.
The main features of paste filling are as follows: ①Mining and filling appeared at the same working face, and the supporting method of filling in coal mines, which needs specialized isolated support, is different from that of metal mines. ②In order to decrease the material cost and deal with the mine waste effectively, the main materials for filling mining are coal gangue, fly ash, riversand, slag and so on with great difference in material quality and weak stability. ③Requirement for filling material strength varies.

These nano-structured silicon materials show a remarkable enhancement on absorptance at near-infrared wavelength.
In these processes, silicon materials are doped with chalcogen, resulting in multiple impurity levels and finally broadening a new impurity band, which can break the limitation of optical band gap of silicon.
Then the comparison of morphologies, light absorptance, minority carrier lifetime with/without SiNx passivation have been investigated on two different nano-structured silicon materials.

Capacitive sensors can respond to and evaluate changes in the physical or chemical properties of a material through variations in capacitive values associated with sensor geometry modifications (such as the distance between two capacitor plates/electrodes, overlapping surface area) or the dielectric material (permittivity) [7].
