Surface tests to determine transport properties of concrete – II: analytical models to calculate permeability


This chapter presents theoretical models for the four tests described in Chapter 3. These are analytical models which use integrated forms of the equations presented in Chapter 1. Two additional tests are described to be used to assess the accuracy of the models; these are a sorptivity test and a high pressure permeability test. The models are used to calculate the sensitivity of the different tests to changes in concrete properties. For practical use the results indicate that the water tests give better results than the gas tests. No clear advantage of either drilled hole or surface tests was observed.
