| Abstract: | First, K _S and K _F are defined as the parameters which represent the influence of unit coefficient of gas permeability on carbonation depth of slag HPC and fly-ash HPC; The relationship between gas permeability and carbonation resistance of HPC was studied by analyzing these parameters; And then, a model for assessing the carbonation resistance of HPC was proposed based on the relationship; At last, the model was proved to be fairly accurate. |

| Keywords: | high performance concrete gas permeability carbonation resistance |
