Effects of Restraint Condition on Carbonation of Concrete Containing Expansive Agent

Abstract:

Article Preview

The concrete containing expansive agent, when limited, is affected by the addition of expansive admixture much, which influence the carbonation resistance. This article makes a comparison with anti-carbonation ability of concrete under restraint and non-restraint condition. The compressive strength and carbonation depth are tested, and the changes of micro-structure are also analyzed with TG-DSC and MIP analysis. The results reveal that single-dimensional restraint condition can efficiently improve the pore structure of concrete. And expansive agent also has a slight improvement to it. Single-dimensional restraint condition can obviously enhance the anti-carbonation ability of concrete containing expansive agent.
