Accompanying drawing explanation
With detailed description of the invention, the present invention is described in further details below in conjunction with the accompanying drawings.
Fig. 1 is general assembly structural representation of the present invention.
Fig. 2 is general assembly structural profile schematic diagram of the present invention.
Fig. 3 is that strip of the present invention interts bolt structure schematic diagram.
Detailed description of the invention
General assembly structural representation as shown in Figure 1, is interted screw 12 by under-chassis 1, lower bottom base 2, motor 3, upper bed-plate 4, Water collecting tube 5, column with holes 6, scale column 7, slump cone 8, fixing nut 9, fixing feeding hopper supporting ring 10, feeding hopper 11, strip and wing nut 13 is constituted.
1) with wet cloth wetting slump cone 8, feeding hopper 11, Water collecting tube 5 barrel and bottom surface and other apparatus, it is desirable to soak and without open fire.Electric concrete mixture workability analyzer is placed on solid horizontal plane, with long spiro nail, slump cone and base is fixed together, by adjusting the position of feeding hopper supporting ring 10, feeding hopper is placed on slump cone 8, and tightens screw.
2) mixed concrete mixture sample scuppit is put into slump cone 8 and feeding hopper 11, start program controller, concrete mix is made to fill slump cone 8 under the effect of vibration, now the concrete in feeding hopper 11 falls, need in feeding hopper 11, to add concrete mix rapidly, until concrete mix fills up slump cone 8 fill to feeding hopper 11 height about 1/2.Whole process control is completed in 20s to charging from starting program controller.After analyzer starts 50s, program controller is automatically switched off.
3) take off feeding hopper 11, remove fixing feeding hopper supporting ring 10, scrape off unnecessary concrete mix floating with spatula.After removing the concrete on the base of cylinder limit, the most smoothly mention slump cone.The mentioning process and should complete in 5～10s of slump cone 8.Should complete in 120s from the whole process starting to be charged to mention slump cone 8.
4) after mentioning slump cone 8, fixing feeding hopper supporting ring 10 on mobile column immediately, concrete mix examination body peak after making supporting ring lower edge and collapsing is equal, the lower limb connecting ring from vertical rod reads scale (in units of mm), and this numerical value is the slump value of this concrete mix.
5) height of liquid level in observation Water collecting tube, according to the color region at liquid level place, it is determined that concrete water-retaining property.As liquid level is starched and aggregate exposure because flowing at the part concrete mix of higher color region or cone, then show that concrete water-retaining property is poor；If liquid level is in lower region, then show that water-retaining property is good.
6), after slump cone 8 lift-off, as examination body collapses or cuts up phenomenon, then should resample is measured.As second time this phenomenon still occurs, then it represents that this mixture workability is bad, should give record for future reference.
7) after measuring and record the slump, water-retaining property, start program controller, observe the performance situation of concrete mix cone under effect of vibration, if cone is gradually sunk, represent that mixture sticks poly-property good；If cone is decayed, part is burst apart or isolation occurs, then it represents that it is poor that concrete mix sticks poly-property.
The above is the preferred embodiment of the present invention, it is impossible to limit the interest field of the present invention with this.It should be pointed out that, for those skilled in the art, technical scheme is modified or equivalent, without departure from protection scope of the present invention.
