Numerical Simulation of Natural and Super-Critical Carbonation on Concrete Porous Brick
Based on the partial differential equations on the carbonation of porous materials, this paper develops the natural and super-critical carbonation model by the multi-physics field coupling software to simulate and predict the relation between carbonation degree and the period of carbonation. It is shown that the carbonation degree after 1 day under super-critical condition is equivalent to that after 1 year under natural condition. The bidirectional carbonation makes the concrete porous brick carbonated faster than the concrete block, thus it is suitable for commercial production.
