This article presents the effect of the cementitious material Silica Fume (SF) as a replacement binder with ordinary Portland cement (OPC) on the compressive strength of Green Ultra High Strength Concrete (GUHSC) containing Ultrafine Palm Oil Fuel Ash (UPOFA) at 28 and 90 days. UPOFA was utilized as a replacement binder by (0, 25, and 50) of the cement mass in GUHSC production. While SF was replaced by (0, 10, 15, 20, and 25) from the remaining cement mass. The Response Surface Method (RSM) was utilized for experiment design and statistical analysis of experimental results. Based on the results obtained, the compressive strengths of GUHSC were lost with a high UPOFA replacement level and gained back significantly by incorporating SF. The statistical findings from the ANOVA model using RSM analysis were empirically verified with an error less than 5; thereby, the predicted and actual results were in acceptable agreement. Thus, using SF as a substitute binder significantly improved the compressive strength of GUHSC containing a high UPOFA volume. Thereby, SF could employ widening POFA utilization in green concrete production, which lessens environmental harm by reducing waste volume and intensive energy for cement production and somehow contributes to cost savings and concrete sustainability. © 2023, The Author(s), under exclusive licence to Springer Nature Switzerland AG.
