This test is part of the family that uses the saturated compressive strength of the material to assess its durability, because if the material has sufficient strength in a saturated state, it will withstand the normal operating conditions of a building without a problem. It takes about 48 h for an earthen specimen soaked in water to be saturated. The specifications of this test are: a minimum compressive strength of 2 MPa in the ‘dry’ state and a minimum compressive strength of 1 MPa at the saturated state plus a requirement that the ratio of saturated to ‘dry’ strength is not less than 0.5. This test was developed to test stabilised CEBs. Hamard, in Modern Earth Buildings, 2012 11.4.4 Saturated to dry strength ratio
