  1. 1.

    Our experiments confirm the fact that the compressive strength of concrete is reduced if it is water-saturated; this is due to the adsorption affects of water, expressed in its splitting action in microfissures and microformations in the stressed concrete. Other conditions being constant, the younger (fresher) the concrete, the lower is the reduction in strength.

  2. 2.

    The effectiveness of the advantageous infuence of deformation constraint of lateral expansion on the strength of compressed concrete in the water-saturated state is lower than in the air-dry state.

  3. 3.

    If the tensile deformation of concrete is strongly constrained (i.e. in strongly constrained conditions of action of concrete), the adsorption effect of water on its strength is negligible.

  4. 4.

    Constraint on the expansion of water-saturated concrete in underwater or water-washed conduits in hydraulic structures, especially tunnel linings, may considerably improve its strength.
