bstract: In the current study, a number of experiments were carried out to compare the mechanical properties of concrete mixes made with Portland cement, fly ash cement, and their mixtures (in 1:0.5 and 1:1 proportion). A replacement silica fume of 5%, 10%, 15%, and 20% was added to concrete mixtures. The materials are combined in the ratios of 1: 1.5: 3. After three days, 14 days, and 28 days, the compressive strengths, workability, and porosity characteristics were examined. By making different types of binder mixes denser, silica fume increases their strength. |
