模拟中放蒸残液(盐含量为400g/1),用525号普通硅酸盐水泥作固化基材,选用新型水泥添加剂“DH_4A”。取水灰比为0.5,制成水泥浆,用差动电阻应变计测定其固化体的膨胀性能。试验结果表明:(1)在20℃密封容器中,废液水泥浆自生体积变形是膨胀。膨胀量较大,三个月的膨胀量达730×10~(-6),比一般混凝土要大十倍,(2)龄期90天
In the simulation, the steamed residual liquid (salt content is 400g / 1) is put into use. The ordinary portland cement No. 525 is used as the solidified base material, and the new cement additive “DH_4A” is selected. Water-ash ratio of 0.5, made of cement slurry, with a differential resistance strain gauge to measure the expansion of the cured body performance. The experimental results show that: (1) In a sealed container at 20 ℃, the self-volume deformation of waste water slurry is swollen. Large amount of expansion, three months of expansion of 730 × 10 ~ (-6), ten times larger than normal concrete, (2) age of 90 days
