Abstract：In order to study the durability of green ductile cementitious composite ( GCC ) , a quick carbonization test was carried out. The carbonation resistant performance of GCC as well as the influence rule of water binder ratio and fiber content on the carbonation performance were studied. The results show that with increasing the carbonization time, the carbonization depth of GCC gradually increases, but the carbonization rate gradually decreases. The carbonation resistant performance of GCC can be improved by adding a certain amount of fiber. However, the carbonation resistant performance of GCC decreases when the fiber content is more than a critical value. The water binder ratio has significant effect on the carbonation resistant performance of GCC. The carbonation resistant performance of GCC gradually reduces with increasing the water binder ratio.
