The concrete should have good and durable engineering property under the ideal condition, but due to the environmental or working reasons, the surface is easily corroded, and even cracked to expedite the neutralization by the CO2 and speed the corrosion on steels, and finally to cause the durability problem. This study is mainly to verify the strategy of restraining the neutralization by adding appropriate pozzolanic admixtures to concrete. The result shows the High Performance Concrete (HPC) with low W/B normally has denser surface, consuming the Ca(OH)2 by pozzolanic reaction and low permeability, which are allowed to restrain effectively the neutralization to decrease the cracking for better durability on concrete.
