| 摘 要： | 以再生微粉砂浆的应用性能为指标,对比研究了五种不同激发剂激发下,两种再生微粉FB和FC砂浆在不同的激发剂用量的情况下,砂浆的孔隙率、平均孔径、孔径分布、抗冻融性能等,研究结果发现LQ1和LQ2激发下,再生微粉砂浆的强度高,干缩小,孔隙率低,孔径分布均匀,吸水率低,抗冻融性好.

| Abstract: | Comparison study is made for the application performance indexes of recycled mortar, i.e.porosity, average pore size, distribution of pore size, frost resistance etc.based on the two kind recycled mortar FB and FC, with different usage of activators.The result has disclosed that the recycled mortar has higher strength, lower dry shrinkage, lower porosity and uniform distribution of pore size, lower dry shrinkage rate and better freeze-thaw resistance at the activating of LQ1 and LQ2 activators. |

| Keywords: | activator porosity average pore size pore size distribution dry shrinkage rate strength freeze-thaw resistance |
