Abstract: Self-compacting concrete (SCC) is undoubtedly a promising ecological cement matrix composite of new generation. However, it is not easy to achieve the required combination of properties in fresh SCC mixes. SCC is also particularly sensitive to any changes in the laboratory and at the job site. Choice of constituents for SCC, especially cement and superplasticiser which are able to collaborate in the correct way, has a signi&#-1279;cant effect on SCC performance. In this investigation considered in qualitative way, four cements, varying in physical and chemical properties and phase composition were used to check their compatibility with a new generation superplasticiser, taking into account the properties of fresh and hardened self-compacting concretes. Results revealed some differences although it is impossible to answer de&#-1279;nitely which cement performs with the superplasticiser in the best way.
