The goal of the project is the development of a prefabricated composite wood-concrete ceiling element that will have no competition on the market. Thanks to prefabrication, it will be possible to ensure the highest possible quality of the ceiling part in combination with the lowest possible requirements for the time required for assembly on the construction site. The subject of research and experimental development will be a prefabricated part achieving the best ratio between the final price of the end product and the useful properties achieved by using innovative materials. The development will be focused mainly on achieving subtle dimensions of the part, so that the lowest possible weight is achieved at the same time as above-standard user, technical, static and acoustic parameters. Part of the development will be verification of the suitability of the use of three different types of supporting reinforcement of the concrete slab. It will be composite basalt reinforcement, composite carbon reinforcement and steel concrete reinforcement. The advantage of composite reinforcements is their high resistance to the negative effects of the surrounding environment, as well as their low weight while maintaining a high load-bearing capacity. The goal of the development is the final product, which will be light, subtle and at the same time sufficiently load-bearing. The disadvantages of composite reinforcements include their higher purchase price compared to steel concrete reinforcement, which does not have the advantages mentioned for composite reinforcements. For this reason, for the development of a new wood-concrete ceiling part, it will be crucial to create a concrete slab that will meet the best possible static and acoustic parameters with regard to the final price of the product.

Another added value of the new wood-concrete part will be an integrated NFC chip, the advantage of which is that it can carry any information about the part. This is mainly information about the location of the part in the structure of the building, so that during the installation of the ceiling structure on the construction site it cannot be confused with another part, or information about the properties of the part or the location of installation penetrations in case of later interventions in the structure of the panel during the life of the building.
