The main purpose of this study is to investigate the effect of using three types of curing (water, painting, and room air) and three different types of water and cement on the strength of self-compacting concrete. Nine mixes containing different cement contents, water cement ratios, and coarse aggregates (gravel, basalt, and dolomite (limestone) were designed. The compression, splitting tensile, and flexural strength tests were carried out on hardened self-compacting concretes after 28 days of curing by water, painting, and room air. In the nine mixes, three cement contents (350,400, and 450 kg/m³), three types of aggregates, and three water cement ratios (0.46, 0.42, and 0.38) were used. Results showed that water curing is the best type of curing to used in self-compacting concrete. Painting curing by Antisol_E liquid does not have effect on the strength of self-compacting concrete. The difference between Painting curing by Antisol_E liquid and having concrete on room air without any curing is very small.
