摘　　要：本文采用人工快速碳化和压汞测孔的试验方法,对不同水灰比、不同减水剂的水泥砂浆试样进行碳化深度和孔结构测定;据此,对碳化深度与孔结构参数的关系进行了定性分析和数理统计分析,发现孔形参数,即管形孔含量对水泥石的碳化性能影响很大,以总孔含量和管形孔含量为自变量,碳化深度为因变量建立的回归方程具有较高的相关系数。Mortars made from various water/cement ratio and water-reducing agents were carbonated under accleratcd conditions Pore structure of the mortars were analysed using mercury intrusion porosimctry It is shown that the poreshape parameter is an important factor infuencing the carbonation behaviour of cement stone Coefficients of binary correlation of the experimental equations between carbonation depth and the pore strucure pafameters(total pore content and tube pore content) arc large.
