โœฆ Synopsis

Measurement of the permeability of concrete to water is complicated by the selfsealing phenomenon, the progressive reduction of flow during the test. Many researchers have attributed self sealing to the hydration of previously unreacted cement on exposure to water. This paper describes permeability tests on concretes continuously hydrated for 26 years. Backscattered electron images show that virtually no unhydrated cement remains in these specimens, yet they exhibit self-seating behavior.

Some concretes of different compositions were tested for several strength properties, having been water-cured, sealed or air-dried before testing. An unorthodox measure of tensile strength, developed at BRE(UK) -and labelled the ACT test here -was included as were measurements of permeability to ni
