Description
Technical field
The invention belongs to test device and the side that premixing mortar performance test field, especially wet mixing mortar stack uniformity
Method.
Background technology
Wet mixing mortar is according to certain ratio by cement, fine aggregate, mineral admixture, water and various functions additive
Mixing, place to use, and the mixture used at the appointed time are transported in mixing plant after metering, mixing.It is different from tradition
Job mix, mixing for premixing dry-mixed mortar use mode, and the centralization production of wet mixing mortar is more beneficial for control of product quality
It is a kind of more environmental protection and advanced production technology with reduction dust, the pollution such as noise, but construction usage relatively low at present
Efficiency, it is desirable to which wet mixing mortar transports rear long-time storage at the scene and retention property is stable at the appointed time.Scene is used to store up
The shaped mortar pool limited volume deposited, the mortar once stacked is highly larger, and mortar is likely to occur more serious point under gravity
Layer phenomenon, i.e. the denseness of upper strata mortar is higher, and lower floor's mortar is hardened, almost without denseness.
Uniformity is stacked to wet mixing mortar at present and does not have a more complete method of testing, scene is simply by range estimation
Whether no the method such as have top layer laitance, isolate qualitatively judge to stack uniformity.This method needs tester to have more rich working
Whether experience can just be judged uniform when mortar is stacked, and can not pass through number for stacking isolated mortar after certain time
It is worth the isolation degree of quantitative analysis mortar.In addition, JGJT70-2009《Building mortar basic performance tests method》In be also situated between
Continued a kind of method for testing coursing degree of mortar, and compared with ocular estimate, delamination degree method can characterize mortar point with data quantitative
Leafing analyses degree, but the stacking of mortar highly only has 300mm in this method, and the resting period of mortar only only has during test
30min, height and use time grave fault are stacked with wet mixing mortar scene.Compared with existing method of testing, this patent institute
The method of testing sampling scope stated is more reasonable, and test device and performance indications can more reflect actual conditions, can be with accurate Characterization
Difference stacks the wet mixing mortar operable time of height.
The content of the invention
The technical problems to be solved by the invention are the stacking uniformities of accurate test wet mixing mortar, and this method is easy, fast
Victory, and realize that wet mixing mortar stacks the quantitatively characterizing of uniformity.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
It is a kind of to test the device that wet mixing mortar stacks uniformity, including hydrostatic column, rubber washer, base, connection lock
Button；
Wherein, described device sets gradually at least five hydrostatic column from bottom to top, wherein undermost hydrostatic column
It is firm with tube chamber welds with base；Rubber washer is provided between each hydrostatic column, rubber washer is pasted onto each hydrostatic column bottom；
For fixed whole test device, each hydrostatic column is attached using connection lock, and connection lock quantity is 4, uniform point
Cloth is in hydrostatic column surrounding.
The hydrostatic column is highly 195 ± 5mm, and internal diameter is 150 ± 1mm, and wall thickness is 5 ± 0.5mm.
The base diameter is 350~450mm, is highly 25~35mm.
The material of the hydrostatic column and base is one kind in stainless steel, plastics, cast iron.
The rubber washer interface is "convex" shaped, its middle and upper part point height 4~6mm, 8~11mm of width；Lower part is high
Spend 4~6mm, 25~35mm of width.
The method that wet mixing mortar stacks uniformity is tested using above-mentioned test device, is comprised the following steps：
(1) assembling instrument and filling mortar：To avoid the phenomenons, assembling such as the highly excessive caused mortar segregation of one-time pad
Instrument and filling mortar should synchronously carry out, the filling of each hydrostatic column assembles last layer hydrostatic column again after finishing, until
Whole mortar fillings are finished；
(2) mortar is stood：Whole test device is positioned over level ground, prevents instrument from toppling over；Standing environment should be with mortar
Scene storage environment is consistent, and particularly the coverage condition of the superiors' mortar should be consistent with scene covering；
(3) it is layered consistency testing：Stand after 12h, the mortar of different layers is taken out respectively, consistency of mortar is used after mixing uniform
Instrument tests the denseness of different layers mortar；
(4) result judgement：If the ratio between this layer of mortar and top layer consistency of mortar are more than or equal to 0.9, it can determine that the stacking is high
The wet mixing mortar uniformity of degree is preferable；If the ratio between this layer of mortar and top layer consistency of mortar are less than 0.9, stacking height can determine that
Wet mixing mortar there is segregation phenomenon, it is necessary to which reducing the stacking height of wet mixing mortar makes the denseness of bottom mortar and top layer mortar
The ratio between denseness be more than or equal to 0.9.
After use above technical scheme, the device that wet mixing mortar of the invention stacks uniformity has advantages below：
(1) it is higher with actual conditions similarity, it both can be used for live mortar operable time test, again can be in experiment
Room carries out simulated test, instructs the stacking height of live mortar.
(2) data reliability is higher, and this method is developed from denseness loss method, inherits denseness loss method intuitively
The advantage of mortar workability is characterized, mortar is solved again and samples not representational enough shortcoming, the reliability of data is higher.
(3) simple to operate, operating personnel only need progress simple training skillfully to grasp whole operation flow.
