The railway sleepers manufacturers, represented in the research project by the project partner PCM RAIL.ONE AG, are aiming to improve the life cycle assessment of their products. However, this improvement has to involve a constant production speed. Consequently, it would be necessary to use cements which combine life cycle benefits with rapid strength development and high durability. For this purpose, cements based on calcium sulfoaluminate (CSA cements) could be used. Their suitability for the production of precast concrete elements will be investigated in this research project using the example of "railway sleepers".
