Abstract:
The paper presents the results of own research on influence of moisture content in mature expanded clay aggregate concrete on some of its physical and mechanical properties. Six states of moisture content have been considered: dry state, state of full saturation with water under atmospheric pressure and four intermediate states. Investigations in intermediate states were carried out after removal of moisture gradients formed during drying process and bringing the moisture field in samples to homogeneous and uniform state. Distinct dependence of concrete properties on its moisture condition was proved. The character of these changes is non-linear, dependent on durability of water constrains with structure of concrete at a given moisture content of the material.
