石膏粉

In conclusion, rubber powder prevents gypsum and ettringite from cubical dilatation, which plays a role as soft elastic body. At the same time, rubber powder can ease cubical dilatation stress, so crack occurrence and development are decreased, and rubberized cement-soil salification erosion resistence is improved.

橡胶粉阻碍了石膏、钙矾石产生的体积膨胀对试件的影响，起到了软性弹性体的作用，缓和体积膨胀应力，减少内部裂纹的发生与发展，提高了水泥土的抗盐蚀性能。
