Machine learning-based prediction for compressive and flexural
网页2021年1月10日The influence of the sand-to-aggregate (S/a) ratio on the strengths of SFRC has been considered as an important factor. Kim et al. [38] discovered that as S/a ratio increases to 0.444, 0.515, and 0.615, respectively, the compressive strength of SFRC is also increased, such as 50.13, 52.62, and 54.10 MPa, respectively.

Steel Fiber Reinforced Concrete (SFRC) Properties, Mix Design
网页Guidelines to serve the purpose of SFRC mix design: Coarse aggregates should be limited to 55% of the total aggregate. Water cement ratio of the concrete should be kept below 0.55 (0.35 is recommended). The SFRC should have a minimum cement content of320 kg/m 3. Reasonable sand content of 750 850 kg/m 3 is recommended.
