“…The Plowman's logarithm curve and the proposed exponential curve should be used with caution, because it does not provide correct results in the final range. Taking into account a wide range of additives, admixtures and various types of cement, every concrete requires an individual approach [28][29][30] An interesting issue would be the analysis of lightweight concrete [31][32][33] using the maturity method.…”

The paper presents the maturity curve for estimating the in-place early-age compressive strength of concrete. The development of appropriate maturity curve is a complex process. It is important to correctly determine the datum temperature and activation energy, which can be obtained in mortar tests. This paper describes an investigation of the accuracy of the maturity method to estimate the strength when different way to rate constant and maturity function are analysed. High performance concrete used for construction of extradosed bridge was tested. The developed curve was implemented to predict the concrete strength at three construction stages, in summer, autumn and early spring.

“…This distinction adopted at the optimization stage brought several economic and structural benefits such as: reduction of the span weight, elimination of negative reaction forces on the ballast spans supports, additionally it allowed for parallel execution of a number of elements to accelerate the working schedule. A normal C50/60 class concrete was used to cast the deck slab in the main span, however the possibility of using light-weight concrete was analysed in other bridges in future as part of the academic work [9].…”

This article presents the execution method of a cable stayed bridge over the Vistula River in Krakow together with FEM-based computational simulations carried out during the design process. The performed calculations concern the global system in its final stage and in the construction stages as well as local analysis of construction details. The obtained results made it possible to work out efficient solutions that contribute to a significant reduction of the project cost and execution time shortening.

“…In the case of underwater structures it is possible to use dispersed reinforcement in a form of steel and polymer fibres [8]. The possibility to modify mechanical properties of concrete makes the structure more resistant to abrasion, erosion and corrosion [9]. Additionally, surface protection by impregnation of precast elements immersed in water makes it possible to build structures in highly aggressive environment [10].…”

The intensive civilization development implies searching for new possibilities connected with extension of city agglomerations, both the areas of flat building and the industrial areas. One of the most interesting solution is to use water reservoirs, rivers and sea areas. The extension of buildings affects the building materials, especially hydrotechnical concrete. Water structures are usually the objects of huge dimensions exposed to extreme conditions. In most cases these buildings are specific and complicated. They require an individual approach to concrete mix design and should be monitored by measurement technologies supported by automated numerical examinations. Nowadays health monitoring systems are applied to large variety of engineering structures. In order to get the required quality of hydrotechnical concrete, additives and admixtures are necessary. The material properties of underwater concrete can be also improved using polymer and steel fibers of various content and length. The majority of areas are built of concrete, that is the reason to be aware of admixture influence on the environment and living organisms. The attempt to evaluate the description of different kinds of hydrotechnical concrete as potential habitat of water organisms, was indicated in the paper.
