STRENGTH AND PERMEABILITY RESULTS FROM A RANGE OF CONCRETES

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 the building research establishment (bre (UK)) -and labelled the act test here was included as were measurements of permeability to nitrogen gas. An analysis of the testing error associated with each test indicated that the techniques were acceptable. Differences in the apparent act strength values of wet and air-dry specimens are thought to be related to the observed permeability behaviour, the former seemingly being much higher than the intrinsic strength.
