| 摘 要： | 通过实验室的试件试验,比较了地聚合物复合水泥(GBC)混凝土与普通混凝土的物理力学性能和耐久性能.试验结果表明,GBC混凝土的干缩小于普通混凝土,抗裂性能高于普通混凝土.GBC具有较好的抗硫酸盐侵蚀性能.GBC混凝土比普通混凝土具有更强的抗氯离子扩散性能,其水溶性氯离子有效扩散系数只有普通混凝土的17%. |
| 关 键 词： | 物理力学性能 耐久性能 氯离子扩散系数 地聚合物复合水泥 混凝土 |

| Abstract: | The physical and mechanical properties and durability properties of the geopolymer blend cement(GBC) concrete and the ordinary Portland concrete(OPC) are compared in laboratory experiments.Results show that the GBC concrete has lower dry shrinkage and higher anti-crack property than that of OPC,that the GBC mortar has better resistance to sulfate attack,and that the GBC concrete has excellent ability to resist erosion of chloride ion with a low diffusion coefficient.The effective diffusion coefficient of water-solubility chloride ion in GBC concrete is 17% of that in the OPC. |
| Keywords: | physical and mechanical properties durability property diffusion coefficient of chloride ion geopolymer blend cement(GBC) concrete |
