Test findings sees Table 1:
Table 1 extraction efficiency and collection efficiency analysis
Analyze and discuss:
1. extraction efficiency
By the experimental result of table 1. as can be seen, the device of described high pressure extraction hardened cement paste hole solution can extract the hole solution of the hardened cement paste of low water-cement ratio effectively.
The principal element that influences the proposition efficient of hole solution has: the quality of pressure size, dwell time and the sample that is extruded.
The pressure of test is big more, and cement sample is just compressed closely knit more, and the hole solution that is extruded will be many more.
Under maximum pressure, the time of pressurize is long more, and the hole solution that can collect will be many more.The device of this high pressure extraction hardened cement paste hole solution is provided with two air holes, can use N
2Or remove CO
2Air discharge air in the collecting chamber, so needn't worry the long dwell time hole solution that is extracted is carbonized, therefore,, can prolong the dwell time relatively if seek out more hole solution.
Under the certain condition of cylinder body volume, the sample of putting into is many more, and then the length-diameter ratio of sample formed cylinder in cylinder body is big more, because the drag effect between the cement granules, the resistance that moisture moves downward also can be big more, so extraction efficiency just can be low more.
2. collection efficiency
After hole solution is extruded out, can be collected efficiently, be vital.Because this device is provided with packing washer and depression generator, keep at collecting chamber under the situation of state of certain negative pressure, being forced out the hole solution that comes can flow in the receiving flask than more smoothly, so collection efficiency is than higher.Mass loss in the collection is mainly because have wetting feeder of a spot of hole solution and collection hole to cause, and the mass loss of this respect is that so the quality of the hole solution that extracts is big more, collection efficiency will be high more by the area decision of feeder and collection hole.If increase the volume of the cylinder body of described device, then can hold more sample, the amount of the hole solution of extraction also can increase accordingly.When the quality of the hole solution that extracts was big, collection efficiency can be near 100%.
3. the advantage of the hole solution that extracts
Owing to be provided with the slit that width is 1～3mm between the feeder of the device of this high pressure extraction hardened cement paste hole solution and the piston hole, played good filtration, therefore collected hole solution is as clear as crystal, does not contain solid particle, has brought very big convenience to experimental analysis.
Conclusion:
This device can extract the hole solution of hardened cement paste smoothly safely, and the hole solution that is extracted can be collected efficiently, and collected hole solution is as clear as crystal, can reach the requirement of check and analysis.
