Experimental Study on Carbonation Behavior of Waste Fiber Recycled Concrete

Based on the rapid carbonization test process of concrete, this paper studies and analyzes the influence of water-cement ratio, recycled aggregate content, fiber length and fiber content on the carbonation rule change of waste fiber recycled concrete. The results show that the depth of carbonization increases with the increase of water-cement ratio. With the increase of the replacement rate of recycled aggregate, the carbonation depth increases. The carbonation depth decreases with the increase of fiber length. As the proportion of waste fiber content increases, the carbonation depth does not change monotonously. The best content is 0.12%.
