However, it is considered low compressive, flexural and tensile strength compared to other types Due to the trend towards using sustainable materials to preserve the environment by getting rid of waste and decreasing the amount of carbon dioxide produced while manufacturing some concrete components by substituting with environmentally friendly materials.
Due to its properties, waste construction materials are increasingly used instead of aggregates in construction projects.

Quantum dot array LED research with ZnO as an electron transport layer Jia Zhao1,a Xiaoyu Zhang1 Yu Zhang1,2 * Yi Feng2 Tieqiang Zhang2 Yiding Wang1 1 State Key Laboratory on Integrated Optoelectronics, College of Electronic Science and Engineering Jilin University, Changchun, China, 130012 2College of Physics Jilin University, Changchun, China, 130012 azhaojia19890718@163.com, *Corresponding Author E-mail:yuzhang@jlu.edu.cn Keywords: CdSe Core-shell Array LED Abstract.As a new light-emitting material, quantum dot having the advantages of other materials that can not be replaced.
But the phosphor is still not the best LED light-emitting materials because light fades, the particles are uniformly poor, life is short.
The quantum dot become the new LED light-emitting materials research focus because it has higher phosphor luminous efficiency,longer life,better color purity.
