Abstract

The rapid chloride penetrating test of ordinary Portland concrete (OPC), glass fiber reinforced concrete (GFRC) and basalt fiber reinforced concrete (BFRC) were carried out under the environment of carbonation. This study investigates the differences of carbonization depth, porosity and permeability with the increase of carbonation ages by comparing the effect of fiber on chloride penetration resistance of concrete, and observing the microstructure through scanning electron microscope (SEM). The results show that glass and basalt fiber increases the porosity of concrete, but the carbonization depth at the beginning of carbonation was reduced, so as to improve carbonation resistance. Carbonation resistance of basalt reinforced concrete is better. Carbonation reaction would enhance the resistance to chloride ion penetration of concrete, which glass fiber performs better than basalt fiber does.
