<p>The aim of this study is to investigate the fresh and hardened properties of the self-compacting heavy-weight concrete (SCHWC) and to develop a mathematical model for the prediction of these properties. The binder was the Portland cement and fly ash (FA). Barite aggregate was used to achieve the heavy-weight concrete (HWC). A polycarboxylate based super plasticizer was used to increase workability and reach self-compacting feature. To research the fresh and hardened properties SCHWC many concrete mixes were prepared accordingly with “water-cement ratios”, “total aggregate-cement ratios”, and “fly ash-cement ratios”. These samples were tested to get the slump-flow, V-funnel, 7 and 28-day compressive strength values. The Response Surface Methodology (RSM) was used to develop regression equations using these experimental results. It is observed that the estimated values obtained with RSM are compatible with those obtained by the experimental method for the fresh and hardened properties of SCHWC.</p>
