This paper studies the effect of the properties (such as slump, cohesiveness, strength, cracking-resistance, etc.) of concrete mixed fiber and mineral admixtures (fly ash, slag) by using the orthogonal experimental method. Through the experiment, we can get and analyze the characteristics of various factors. According to the local material characteristics, obtain a best cyanide dosage of the mineral admixtures and fiber; And through comparison in the optimum content of concrete and the reference concrete (without fiber), study the resistance performance of fiber.
