The strength of red sandstone in water disintegration and the expansion potential of red sandstone is called the activity of red sandstone. The magnitude of the stronger swelling potential of disintegration in water is called the activity of red sandstone. The stronger the soaking and disintegration of the red sandstone, the greater the activity. When used to build embankments, the more active red sandstone is, the more likely it is to form a subgrade disease.
