Secondary compression of clays
WebIt is inelastic, time dependent and only partially recoverable; while the secondary compression is due to creep movements – plastic adjustment of soil fabric under a constant effective stress. This is also inelastic, time dependent and unrecoverable. The elastic deformation of soils is discussed in Chapter 4.

During the construction of … WebDe Bruyn & Thimus (1996) performed an undrained heating test on Boom clay at a constant heating rate of 0.5°C/min from 30°C to 75 °C and then kept the temperature constant at 75°C. They recorded a continuous increase in pore-water pressure, even under constant temperature conditions.
