The goal of this project is to develop timber-concrete composite floor element with no competition on the market. Thanks to high level of prefabrication, we will be able to obtain the floor element´s highest quality while the lowest requirements for construction time on site. The subject of research and experimental development is fully prefabricated element achieving the best rate between final price and its utility properties thanks to innovative

materials. The development will be especially focused on subtle element dimensions, because it is needed to reach its the lowest possible weight with above-standard technical, static and acoustic parameters. One part of the development will be convenience verification of three different load bearing reinforcement types in concrete slab. The types are composite basalt reinforcement, composite carbon reinforcement and steel reinforcement. The advantage of composite reinforcement is its high resistance to adverse environmental influences and also its low weight when it still has high bearing capacity. The purpose of the development is final product, which will be light, subtle and will still have enough load bearing capacity. One of disadvantages of composite reinforcement is its higher price compared to steel reinforcement, which is cheaper, but doesn´t have advantages named for composite reinforcement. That´s why the development of new timber-concrete floor element will be based on concrete slab prefabrication with the best possible static and acoustic parameters with respect to final price of whole product.

Another added value of new timber-concrete element will be integrated NFC chip, which has the advantage of carrying variable information about the element. That includes especially place of the element in construction to prevent substitution by another similar element or information about element properties or installation hole locations used in case of later changes in panel structure during the life of the building.
