Description
Technical field
This utility model is specifically related to a kind of concrete thixotropic property assay device.
Background technology
The service behaviour of fresh concrete is to determine concrete mix property of complexity when pouring, consolidate and wiping one's face
Matter, relates to the following aspects: one, mobility (filling the complexity of model)；Two, the Yi Mixing (difficulty or ease that bubble is discharged
Degree)；Three, cohesiveness (maintaining the ability of uniformity), excellent workability, be to ensure that the uniform closely knit molding of concrete, have
Excellent apparent mass and the premise of good durability.The easiest close property is in fresh concrete overcomes during deadweight or tamping
Portion's frictional resistance and reach the ability of the compaction rate of requirement, i.e. bubble discharge complexity, be also that concrete mix is shaking
The size of puddling real-time institute wasted work, the thixotropic property of concrete is relevant to easy the to be close property of concrete, but at present at laboratory evaluation
Whether fresh concrete has good thixotropy and not yet has preferable method.
Utility model content
The purpose of this utility model is to provide a kind of concrete thixotropic property assay device.
Concrete technical scheme of the present utility model is as follows:
A kind of concrete thixotropic property assay device, including the metal of a upper opening or the cuboid box of plastic material and
The some hollow rigid plastic balls being homogeneously disposed on the bottom surface of this cuboid box, a length of the 280 of this cuboid box～320mm,
Width is 180～220mm, and height is 180～220mm, and inner wall surface thereof is drawn has Concrete Filled to reach the standard grade；This hollow rigid plastics
The diameter of ball is 20～50mm, and wall thickness is 0.5～2mm.
In a preferred embodiment of the present utility model, the both sides of described cuboid box are respectively provided with a hand-rest plate, with
It is easy to mobile described concrete thixotropic property assay device.
In a preferred embodiment of the present utility model, a length of 300mm of described cuboid box, width is
200mm, height is 200mm, and the material of cuboid box is rustless steel or plastics.
In a preferred embodiment of the present utility model, the diameter of described hollow rigid plastic balls is 40mm, wall
Thickness is 0.5mm, and its material is celluloid, polyethylene terephthalate, Merlon, amino resins, polyethylene
Or polypropylene.
In a preferred embodiment of the present utility model, the number of described some hollow rigid plastic ballses is 2～4.
The beneficial effects of the utility model are:
1, this utility model includes the metal of a upper opening or the cuboid box of plastic material and to be homogeneously disposed in this rectangular
Some hollow rigid plastic balls on the bottom surface of body box, hollow rigid plastic balls is the bubble in simulation concrete, by hollow firmly
Matter baton round is uniformly positioned in cuboid box, then by Concrete Filled to reaching the standard grade of delimiting, is positioned on vibration table, passes through
Vibration table vibration makes hollow rigid plastic balls float to shake visible to naked eyes, and this period is hollow rigid plastic balls when shaking
Between, use stopwatch to carry out timing, the meansigma methods of time of shaking by each hollow rigid plastic balls of calculating, can be evaluated this and newly mix mixed
The thixotropy of solidifying soil.
2, the complexity that this utility model is discharged by simulated bubble, can evaluate touching of fresh concrete the most efficiently
Degeneration energy, method of testing is simple, low cost, test speed are fast.
Accompanying drawing explanation
Fig. 1 is the perspective view of rectangular box body of the present utility model；
Fig. 2 is top view of the present utility model.
Detailed description of the invention
Below by way of detailed description of the invention combine accompanying drawing the technical solution of the utility model is further detailed and
Describe.
As illustrated in fig. 1 and 2, a kind of concrete thixotropic property assay device, including metal or the plastics material of a upper opening
The cuboid box 11 of matter and the four hollow rigid plastic ballses 12 being homogeneously disposed on the bottom surface of this cuboid box 11.
The a length of 300mm of this cuboid box 11, width is 200mm, and height is 200mm, and the material of cuboid box 11 is
Rustless steel or plastics, inner wall surface thereof is drawn and has Concrete Filled to reach the standard grade 111, and the both sides of cuboid box 11 are respectively provided with a hand-rest plate
110, in order to mobile described concrete thixotropic property assay device.
The diameter of this hollow rigid plastic balls 12 is 40mm, and wall thickness is 0.5mm, and its material is celluloid, gathers
Ethylene glycol terephthalate, Merlon, amino resins, polyethylene or polypropylene.
Fresh concrete is poured in this cuboid box 11, reach Concrete Filled and reach the standard grade 111, then this utility model is put
On vibration table 2, making hollow rigid plastic balls floating shake visible to naked eyes by vibration table 2 vibration, this period is sky
Heart rigid plastic balls shakes the time, uses stopwatch to carry out timing, shakes the average of time by calculating each hollow rigid plastic balls
Value, can evaluate the thixotropy of this fresh concrete.
The above, preferred embodiment the most of the present utility model, therefore this utility model can not be limited according to this and implement
Scope, i.e. according to this utility model the scope of the claims and description made equivalence change with modify, all should still belong to this practicality
Novel contain in the range of.
