The cement particles are divided into three fractions[12]: the middle particle of 3~32um will play a major role on strength; less than the fine-grain pellet 3 um, its content should not exceed 10%; the coarse particles are greater than 60um, which do not work on strength, can only be used as a filling material.
Where ψ (Dp) is the number of accumulated screen residue which larger than Dp (volume fraction); De is the particle group more than 36. 8%; n is uniformity index.

It has been known that oxygen is chemisorbed on the ZnO surface and in pores in the films, and nanocrystalline grain boundaries act as a surface potential barrier, which may cause a low mobility.

Meanwhile, a large number of researchers focus their attentions on the rare earth optical materials, since their novel electronic and optical properties resulting from their 4f electrons, such as emission lifetimes, luminescence efficiency and concentration quenching result substantially affected [3].

In order to improve the compatibility and avoid repeated efforts, growing number of specification organizations have committed to developing cloud computing security standards abroad, such as ITU-TSG17 study group[6], Organization for the Advancement of Structured Information Standards(OASIS)[7] and Distributed Management Task Force [8].In addition, some dedicated organizations, such as cloud computing security alliance [9], also made some progress in cloud computing security standardization.
Meanwhile, we should also use a virtual machine security mechanisms monitor and purify the flow on the virtual machine backplane fine-grained.

Introduction
Rheological properties of fresh concrete are one of the factors determining its use and depend on a number of variables, such as cement type, dose and type of plasticizing admixtures, type of aggregate, type of ingredients used, environmental temperature and finally delivery time of fresh concrete to the construction site [1], [2].

Today the large number of cement-based materials are need by humans engineering activities every year, such as cement grouting material with more than milion ton, so it hleps if those waste can be used to the cement-based materials.
The reason is: with an appropriate amount of Ca2+ and SO42- supplied by the dissolution of gypsum, the formation of ettringite slows down the hydration of C3A by creating a diffusion barrier around C3A grains,and then the fluidity increases.

Since the different water quality between desalinated water and conventional treated drinking water, a considerable number of studies exist that describe the potential problems that may occur when waters that have different chemical characteristics are supplied intermittently into distribution systems[6] When desalinated seawater is transmitted in water distribution system, it could destroy the original balance of pipe networks and would result in the substandard effluent in pipe ends such as high turbidity, chromaticity or iron content caused by iron release[7].
