This experiment studies the influence of different fiber content on the mechanical properties of concrete under simulated acid rain environment (pH=2.5) in the laboratory. Under the action of acid rain erosion, the total content of carbon fiber and basalt fiber are respectively 0.1%, 0.2%, and 0.3%, of which carbon fiber and basalt fiber each account for 50% of the total content. The experiment adopts the cycle immersion method to study the laboratory to simulate acid rain to accelerate the corrosion of concrete. After simulating acid rain corrosion for 25 days, it is naturally dried for 5 days. The compressive strength and splitting tensile strength are measured. The comparison shows that when the total fiber content is 0.2%, the concrete the tensile-compression ratio of the test block is the largest, and its splitting tensile strength increases by 15.09% as the maximum.
