至今,国内在水灰比测试方面虽已有多种方法,但所需时间都比较长。最短的容量筒法做一次水灰比分析尚需20分钟。我们用此法做过多次分析,均需30分钟左右。国外现在大都采用专用的分析设备或液体天平进行这项工作。这在我国的一些基层建筑单位和建材工厂,近期内是不能实现的。鉴于上述情况,本人利用本厂现有设各,经过大量试验,初步摸索出了一套新的测试方法——体积法。体积法有三大特点: 1.分析时间短。整个测试过程只需5～10分钟。
So far, although there are many methods in water-cement ratio testing in China, the time required is relatively long. It takes 20 minutes for the water-cement ratio analysis to be performed for the shortest capacity cylinder method. We used this method to make multiple analyses and it takes about 30 minutes. Most foreign countries now use dedicated analytical equipment or liquid balances to do this work. Some of the grassroots construction units and building materials factories in China cannot be realized in the near future. In light of the above, I have used our existing facilities and through a large number of tests, I have found out a new set of testing methods—volume method. The volume method has three major characteristics: 1. The analysis time is short. The entire test process takes only 5 to 10 minutes.
