Description
Technical field
The utility model relates to the sand-cement slurry checkout equipment, particularly a kind of emulsification asphalt cement mortar fluidity high speed tester.
Background technology
The middle bed course of railway plate-type slag-free orbit is the CA bedding mortar, i.e. the emulsification asphalt cement mortar bed course.It is stirred and makes through special process at normal temperatures by starting material such as cement, emulsified asphalt, admixture, fine aggregate, water, surfactant, water reducer, polychloroprene latexs.The CA bedding mortar must have certain intensity and suitable elasticity, also should have good stable and permanance.In order to fill the gap between track plate and the concrete base bed board, require the CA mortar to possess suitable injection flowability.Because cement and emulsified asphalt just react once mixing, and cause viscosity to increase gradually, so the up time of CA mortar are limited.The flowability of CA mortar is subjected to the influence of temperature, match ratio and mixing plant and technology, so operations such as the CA mortar must cooperate at the scene, stirring, injections.For the track plate that keeps the adjusted location does not produce mobilely, generally adopt the gravity flow perfusion, rather than pressure injects.
In order to satisfy the pouring construction needs, after the CA mortar stirs, suitable viscosity should be arranged and can keep the regular hour, make it can fill space under the plate.The CA mortar also should have construction environment adaptability preferably, to satisfy the requirement of constructing under the Various Seasonal climatic environment.CA mortar curing rate should satisfy the follow-up work needs, from the different times that is filled into curing different intensity indexs should be arranged, and the uniform state when each constituent should keep mixing after solidifying can not separate.Expansion to a certain degree should be arranged after the primary solidification,, provide certain prestress simultaneously to be full of residing space fully.For guaranteeing the construction quality of CA bedding mortar, there is concrete technical requirement in China railways department to the CA mortar; CA mortar fluidity and operable time are important techniques indexs wherein, also are the important indicators that guarantees plate type slag-free orbit CA mortar in-site pouring construction quality.For determining the fluidity of CA mortar, present detection method is: the employing volume is that the special funnel of 640ml is measured; In the CA mortar hopper that is about to mix and stir, open the lower end outlet, pick up counting simultaneously, mortar all flows out the time of being experienced from funnel, is the fluidity of mortar, in the time (second).The fluidity of certain limit is extremely important for the performance and the pouring quality of mortar, and segregation can appear in fluidity too small (mortar is thin), mortar material, influences its intensity and permanance; Fluidity excessive (mortar thickness) then is difficult to the space between track plate and basis is filled closely knit, influences its intensity and permanance; So CA mortar fluidity is too small and excessive, all directly influence pouring quality.Railway interests is in conjunction with a large amount of tests, determines that the fluidity index is in 16～26 seconds scopes.The operable time of CA mortar is meant that the CA mortar is in the time of being experienced in the fluidity scope of regulation, consider on-the-spot from the mortar blending station prepare, transportation, needed time of perfusion operation, the operable time of regulation CA mortar is no less than 30 minutes.
Because the factor that influences CA mortar fluidity and operable time is a lot, in the mode of mixing and stirring, under the certain condition of feeding sequence, fluidity and operable time are different with the variation of the match ratio of temperature, additive, main raw material(s), water cement ratio.So in CA mortar injection process, require to do a fluidity test every 5min; Meet the demands and just can pour into; If fluidity is undesirable, then this dish CA mortar must be discarded.The testing amount of CA mortar turnover rate is huge in the work of historical facts or anecdotes border, and utilize existing funnel detection method to waste time and energy, so be badly in need of developing a kind of emulsification asphalt cement mortar fluidity high speed tester that instrument is light and handy, easy to use, simple to operate, detection speed is fast, data are accurately objective, testing result can be stored advantage automatically that has.
