Another way of improving concrete production involves incorporating the unique features of high performance concrete with the special properties of self-compacting concrete, resulting in another type of concrete called high performance self-compacting concrete (HPSCC). Many researchers have developed diverse designed control mix for HPSCC which were obtained through several and rigorous designed trial mixes. Yet, little work has been done on prescribed control mix for HPSCC. The purpose of this paper is to establish a prescribed control mix ratio for HPSCC and to test by conducting compressive strength test. Review of the various designed control mix ratios is done in this paper. A logical prescribed control mix ratio of 1:1.02:0.95 has been established for an HPSCC with 0.36 w/c proportion, 0.02 superplasticizer/cement proportion. The compressive strength gave 36.10 MPa at 7 days curing age, 41.76 MPa at 14 days curing age and 57.29 MPa at 28 days curing age. This strength result satisfied the strength criteriaa of HPSCC, according to EFNARC It is therefore recommended that a prescribed control mix of 1:1.02:0.95 be used if the minimum crushing strength value expected at 28 days is 40 N/mm 2 for an HPSCC.
