At the same strain level, the damping ratio of LCES is smaller than soft clay's, and it decreases to a quite low level with high cement content and low EPS content.

This rock contained chalcedonic cement before it underwent diagenesis, a process where low temperatures and low pressures alter the content of sediments before they finally lithify, or turn into rock.

This paper emphasizes the development, quality and application of corundum castable refractories of high purity, low cement-content.
