Abstract: In this paper, the results of a laboratory work predicting the compressive strength of silica fume (SF) concrete by accelerated warm-water curing method (WWM) have been presented. A parametric study has been carried out by producing a total of 48 concrete mixtures with three different cement dosages (350 kg/m³, 400 kg/m3, 450 kg/m3), four different water-cement ratios (0.3, 0.4, 0.5, 0.6) and four SF replacement ratios with cement (0%, 10%, 15%, 20%) on mass basis. Control normal Portland cement (NPC) concrete and SF concrete are cured with accelerated WWM in accordance with ASTM and Turkish standards. The linear relations have been established between accelerated WWM compressive strength and 28-day compressive strength for NPC concrete and SF concrete, separately. Although, the inclusion of SF influences the parameter of prediction equation when compared to NPC concrete, the analyses of the results indicate that prediction of SF concrete compressive strength by accelerated warm-water curing is possible with correlation coefficient (R²) higher than 90%.
