Hybrid fiber reinforced concrete possessing both strength and durability was developed using the orthogonal test method. Various factors' effects on the fundamental properties of hybrid fiber-reinforced concrete were investigated. The results indicate that the water-binder ratio significantly influences compressive strength. Both the basalt fiber content and polyvinyl alcohol fiber content significantly impact fluidity. Both water-binder ratio and polyvinyl alcohol fiber content significantly affect electric flux, which decreases with increasing fly ash content. The hybrid fiber-reinforced concrete underwent comparison and evaluation via range analysis and variance analysis, culminating in the determination of the optimal concrete mix ratio using the efficiency coefficient method. This concrete exhibits superior strength and enhanced resistance to chloride penetration, making it more suitable for harsh environments. |
