| 中文摘要: |
| 为探讨硬化砂浆中可溶性SiO2含量测定方法——硅钼蓝分光光度法，试验了待测液的不同处理浓度方法和显色液放置时间对吸光度的影响，结果表明：可以通过控制取液量和取样量来调节待测液浓度，显色后的待测液不可再次稀释测其吸光度，加入还原剂的显色液最好在放置60 min后的10 min内测完吸光度。 |
| 英文摘要: |
| In order to discuss the determination method of soluble SiO2 in hardened mortars——silicon molybdenum blue spectrophotometry method, the different treatment concentration methods of the test solution and the effect of standing time on the absorbance of the chromogenic solution were tested, the results shows that the test liquid concentration can be adjusted by controlling the amount of liquid and sample, and the chromogenic sulution must not be diluted again to test its absorbance, and the chromogenic solution that added reducing agent should be measured within 10 minutes after 60 minutes of placement. |
