This paper presents and evaluates a new method for producing Slurry Infiltrated Fiber Concrete (SIFCON). A study was carried out to investigate the impact on the mechanical properties of SIFCON, where several cubes, cylinders, and prisms were cast to compare the proposed gradual and the traditional multi-layer method using the same mixing proportions: 6% straight steel fiber, cement, sand, 10% silica fume replacement, and 2.4% superplasticizer. The results showed that when using the proposed gradual mix method, compressive strength, splitting tensile strength, modulus of elasticity, and modulus of rupture improved by 15.21%, 8.06%, 9.07%, and 5.26% compared to the traditional multi-layer method.
