New mixes were prepared according to the EFNARC self‐compacting concrete criteria with synthesized polycarboxylate‐type superplasticizers. For this purpose, superplasticizers possessing different side‐chain lengths and cross‐linkages were produced to overcome the workability and workability‐retention problems in self‐compacting concrete (SCC) by time. Not only the fresh properties but also hardened properties of SCCs were improved. With this study it was determined that, cross‐linked polycarboxylate‐type superplasticizer shows better performance in SCC compared to its counterparts and commercial polycarboxylate. It provides better self‐compaction by discharging its bubbles during molding. Besides, the effects of water‐powder ratio and superplasticizer dosage were also examined and discussed in this study.
