Therefore, taking FGD gypsum and fly ash as cementing materials, compositing wheat straw as reinforcing material and adding the necessary admixtures to manufacture gypsum block has the dual benefits of the economic and environmental.
Raw materials FGD gypsum.
As cementing materials hydrate, the waterproofing, evenly dispersed in the paste, also begins to gather in structure pores and forms closed pores and structural gaps.

Introduction Nickel-based superalloys are a group of materials, commonly used for high temperature application, in which high strength, good corrosion resistance and excellent fatigue resistance are needed.
Vitrified CBN grinding wheel is one of the most promising abrasive tools for its outstanding properties, such as high material removal rates, high heat resistance, low total cost and so on[3].
