Abstract: A method for determining an optimal fiber content and fiber slenderness ratio in compression-cast fiber-reinforced concrete (CCFRC). The method includes: step 1, determining an optimal range of pressure of CCFRC with a mix proportion; step 2, applying optimal compressive stress to a fiber-reinforced concrete mixture, and performing a uniaxial compression test after demolding and curing; step 3, keeping the slenderness ratio of the fiber in step 1 and the optimal compressive stress in step 2 unchanged, decreasing or increasing content of the fiber, and repeating step 2 to obtain a mechanical property of CCFRC with different content of the fiber; and step 4, keeping the content of the fiber in step 1 and the optimal compressive stress in step 2 unchanged, decreasing or increasing a slenderness ratio of the fiber, and repeating step 2 to obtain a mechanical property of CCFRC with a different slenderness ratio of the fiber.
