It has been confirmed by many authors that the specific fracture energy of concrete determined by laboratory experiments depends on the shape and size of the specimen because the local energy in the fracture process zone is influenced by the free sur

Carbonation of hydrated cement paste (HCP) under γ-irradiation is researched in this paper. It is supposed that radiation-induced carbonation takes part simultaneously with “natural” carbonation. “Natural” carbonation is governed by diffusio

Influence of curing temperature applied to hardening cement paste during the early induction period of hydrating (which is closely connected with so-called workability of concrete mixture i.e., with the period during which the material is formative a

A method is proposed, which allows evaluation of moisture in building envelopes taking into account sorption properties of timber or other materials with pronounced sorption. This is essential in many situations when apparently no risk of degradation

Structure changes of the cement gels of concrete PENLY and TEMELIN are carried out under the influence of the heat load in the temperature range 25–910°C. These changes are studied in the region of micro- and mesopores using the methods of physica
