混凝土表面覆盖的碳化延迟系数研究

AStudy on the Carbonation Retarding Coefficient of Concrete Surface Coating

在人工碳化条件下研究了10种覆面材料对混凝土碳化的影响。分别计算了每种覆面的碳化延迟系数。研究结果说明,密实少透气的覆面材料对延迟混凝土的碳化是很有效的。这些覆面材料可有效地作为混凝土表面的抗碳化保护层。

The influence of surface coatings of 10 types on the carbonation ofconcrete under artificial condition is discussed in this paper. The carbonationretarding coefficient β of each surface coating has been worked out. Result ofinvestigation shows that coating materials with high density and low airpermeability are ideal to be used for retarding the carbonation of concreteand they can serve effectively as protective coating against carbonation ofconcrete.
