| Abstract | ||
| In this research, molds from fifteen concrete mixes were prepared to find the compressive strength and shrinkage using five levels of silica fume and three ratios of steel fibers. Based on the results of the study, the addition of steel fibers lead to reduce the 90 days shrinkage up to 59% , while the silica fume lead to an increase in the shrinkage of the concrete up to 84%. Results were compared with shrinkage of four supported models, the first model of equation (CEB), second model of equation (GL2000), third model of equation (B3) and the fourth of (ACI 209-93). Results of the comparison showed that the shrinkage by the ACI equation is the least.Shrinkage, High strength concrete, Steel fibers, Silica fume | ||
