✦ Synopsis

Measurements of the strength of one concrete under conventional triaxial compression, "extension", and tension plus biaxial compression are described. The concrete specimens had a water/cement ratio of 0.47 and an aggregate/cement ratio of 3.9, and were tested in a moist condition at four ages, 7, 14, 28 and 56 days. Relationships are given for the dependence of the failure stresses of the particfilar concrete tested upon (a) the applied stresses and the specimen age and (b) the applied stresses and the compressive strength of the concrete at atmospheric pressure.
