Question

The data below are from a loading increment in a consolidation test. The thickness of the specimen at time t=0 is 25.4 mm. The specimen is drained from both top and bottom. Using the square-root of time method, the time for 90% consolidation is most nearly:

Answer 1

given the above data 90% consolidation would be
`(25.4)/(100) X 90%` =22.86

Step-by-step explanation:

For the above to be feasible we need to have the original thickness divided by the total percentage which is 100 then multiplied by the new percentage which is 90% since t is at the origin , i.e t=0.

The Consolidation test: is used when we wish to determine the rate and magnitude of consolidation when it is restrained laterally and loaded axially.
