Description
Technical field
The present invention relates to a kind of concrete flowability test device, belongs to architectural engineering Test And Check Technology field.
Background technology
Concrete is that modern construction engineering consumption is maximum, the construction material that purposes is most wide, the workability of concrete mix
（Or claim workability）It is to ensure that concrete batching system is easy to constructing operation（Mix and stir, transport, pour, consolidate）And it is equal to obtain quality
The important performance of even closely knit concrete structure, reflection is concrete mix under the deadweight or construction machinery effect of vibrating
Readily flowed performance, depending on the denseness of mix.Workability is the basic nature that must be controlled in concrete preparation process
Can, and include mobility, three indexs of cohesiveness and water-retaining property（High performance concrete should also contain plasticity, easy modified,
Fillibility, pumpability and stability etc.）.As cohesiveness and water-retaining property are difficult directly test, in practice, only test concrete is mixed
The mobility of compound, is aided with the observation to its cohesiveness and water-retaining property, then according to determine and observation result overall merit itself and
Yi Xing.
For testing the mobility of concrete mix, multiple devices, such as slump cylinder, stream latitude of emulsion examination were once developed in the world
Test instrument, remoldability tester, the stream latitude of emulsion testing stand of Germany, Kai Li (Kelly) ball indentation test instrument, Nasa K- probes etc..Slump
Degree cylinder is simple due to device, and index is clearly, therefore widely used for countries in the world always.
Existing slump cylinder is made up of slump cylinder, pedal and handle, typically have standard slump cylinder and
Increase two kinds of sizes of slump cylinder.Standard slump cylinder is applied to the maximum aggregate size no more than concrete mix of 50mm
Fluidity testing, and increase the fluidity testing that slump cylinder is applied to the concrete mix of 50mm～80mm.Standard slump
The basal diameter of degree cylinder is 200mm, a diameter of 100mm of top surface, is highly 300mm；The size for increasing slump cylinder is that bottom surface is straight
Footpath 300mm, top surface diameter 150mm, height 450mm.
During the test that concrete mix mobility is carried out using existing slump cylinder there is inconvenience.The first is necessary
At least two people can just complete test job, and people's bi-pedal lives the pedal of slump cylinder makes which be fixed on test base plate, separately
One people is fed.Which two is that the personnel of foot-operated slump cylinder must use both hands and feet, and loads the big concrete mix of fluidity
When, such as careless slightly, cement slurry will be trickled down on both feet and can be made dirty trousers, is also possible to when being fed with instruments such as spades sometimes
Damage operator, and during whole operation, it is necessary to slump cylinder is consolidated on base plate motionless, such as trample loosely,
Have mixture to flow out from cylinder bottom.Which three is during slump cylinder is lifted often to be difficult to ensure that perpendicularity, makes concrete
Mixture sample receives horizontal and twisting force and produces inclination when hanging, and brings error to result of the test；And
A ruler, a slump cylinder and a mark post, the perpendicularity of ruler and mark post is usually needed to place during the test slump
Levelness all will affect the precision of test result, while test result is also lifted speed and subjectivity by operator to slump cylinder
The impact of error in judgement.It can be seen that, although existing concrete slump method of testing device is simple, operation inconvenience, testing efficiency
Low and unhygienic, measuring accuracy is difficult to ensure that.
