The Behavior of Hardened Cement Paste test material preparation mould tested by above-mentioned vibration cementing can make in same vertical direction height
Go out two pieces of identical Behavior of Hardened Cement Paste, when testing the intensity of Behavior of Hardened Cement Paste, if finding the data of Behavior of Hardened Cement Paste in same vertical direction height
Differ larger, then it is considered that error, mistake or unreasonable place during Behavior of Hardened Cement Paste is this time made be present, water should be remake
Mudstone, the Behavior of Hardened Cement Paste of this making cancel.
The Behavior of Hardened Cement Paste test material preparation device of above-mentioned vibration cementing experiment prepares the operation step of Behavior of Hardened Cement Paste test specimen in this application
Rapid process is as follows, and the process comprises the following steps：
Step 1：Seal grease will be smeared on the inwall of the Behavior of Hardened Cement Paste test material preparation mould of vibration cementing experiment.Seal grease
When splicing the Behavior of Hardened Cement Paste test material preparation mould of vibration cementing experiment, it on the one hand can improve and engage or offset between different parts
The sealing at place, still further aspect are easy to the dismounting of mould after cement mortar condenses into Behavior of Hardened Cement Paste, avoid removing the process of mould
In the surface of Behavior of Hardened Cement Paste is caused to damage.
Step 2：First partition 1, second partition 2, the 3rd dividing plate 3 and bottom plate 6 are stitched together to form the and of the first cavity 9
Second cavity 10.In a kind of feasible mode, by inserting fixture in the hole 26 of the dividing plate 3 of second partition 2 and the 3rd
25, the screwed hole 27 of first partition 1 is screwed into by fixture 25 to realize the spelling of first partition 1, second partition 2, the 3rd dividing plate 3
Connect fixation.By by bottom plate 6 be arranged on first partition 1, second partition 2, the 3rd dividing plate 3 lower section, and connecting rod 7 is penetrated
In the through hole 121 of one dividing plate 1, while the screwed hole being screwed on bottom plate 6.
Step 3：The cement mortar prepared is uniformly poured into the first cavity 9 and the second cavity 10.In this step, will make
The first predetermined position that the cement mortar got ready is uniformly poured into mould the first cavity 9 and/or the second cavity 10, the first default position
Put can the quantity of demarcation strip 4 as needed determined that the first predeterminated position can be the position that first piece of bottom demarcation strip 4 inserts
Put place.Certain puddle is carried out to the cement mortar that pours into, then proceedes to add cement mortar successively to the second predetermined position, second
The determination of the particular location of predeterminated position is identical with the determination principle of the first predeterminated position.Carry out one again after cement mortar is added into
Fixed puddle, aforesaid operations are so repeated to the top added in cement mortar to the first cavity 9 and/or the second cavity 10.
Step 4：Cover plate 5 is covered on die ontology and is fixed.In this step, the lid of seal grease will be coated with
Plate 5 is covered on first partition 1, second partition 2, the 3rd dividing plate 3, and unnecessary cement mortar can be overflowed by the guiding gutter 51 on cover plate 5,
Struck off and cleaned out with ruler, showed if spillage occurs for the Behavior of Hardened Cement Paste test material preparation mould side wall of vibration cementing experiment or bottom
As then discarding the test specimen, re-starting making.Have no problem, connecting rod 7 is connected with cover plate 5.
Step 5：The Behavior of Hardened Cement Paste test material preparation mould that vibration cementing equipped with cement mortar is tested vertically is placed on
Vibration test is carried out on vibrating device, i.e. bottom plate 6 is disposed below, and cover plate 5 is placed on top.
Step 6：After vibration test terminates, it is empty that the demarcation strip 4 for being coated with seal grease is inserted into the first cavity 9 and second
In chamber 10 and it is fixed, to cause cement mortar in the vertical direction to be divided into some.In this step, will first smear
There are the first gap slot 23 of different height for being opened up in the side wall of the luxuriant insertion second partition 2 of demarcation strip 4 of seal grease and the
Second gap slot 33 of the different height opened up in the side wall of three dividing plates 3, demarcation strip 4 pass through first partition 1, the and of second partition 2
Chute 8 in the side wall of 3rd dividing plate 3 is inserted in the first cavity 9 or the second cavity 10.Again by the dividing plate of second partition 2 and the 3rd
Fixture 25 is inserted in 3 through hole 24 so that demarcation strip 4 to be fixed.
Step 7：The Behavior of Hardened Cement Paste test material preparation mould that vibration cementing is tested is conserved, disassembles and shakes after maintenance terminates
The Behavior of Hardened Cement Paste test material preparation mould of dynamic well cementation experiment is to obtain Behavior of Hardened Cement Paste.In this step, the water that vibration cementing can be tested
Mudstone test material preparation mould is placed in water bath according to the temperature and pressure condition needed for experimental program and conserved, maintenance knot
A period of time is cooled down after beam, then extracts demarcation strip 4, disassembles the Behavior of Hardened Cement Paste test material preparation mould of vibration cementing experiment to obtain
The Behavior of Hardened Cement Paste formed on polylith difference vertical direction.Finally by vibration cementing experiment Behavior of Hardened Cement Paste test material preparation mold clean and dry in the air
It is dry, in case experiment is continuing with next time.
