Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in further details.
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 the rectangular interspersed bolt structure schematic diagram of the present invention.
Embodiment
General assembly structural representation as shown in Figure 1, is made up of 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, hold-down nut 9, fixing feeding hopper supporting ring 10, feeding hopper 11, rectangular interspersed screw 12 and wing nut 13.
1) soak slump cone 8, feeding hopper 11, Water collecting tube 5 barrel and bottom surface and other apparatus with wet cloth, require wetting and without open fire.Electric concrete mixture workability analyzer is placed on solid surface level, with long spiro nail, slump cone and base is fixed together, by the position of adjustment 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, concrete now in feeding hopper 11 falls, need in feeding hopper 11, to add concrete mix rapidly, until concrete mix fills up slump cone 8 and fills with about 1/2 to feeding hopper 11 height.From startup program controller to having fed in raw material whole process control in 20s.After analyzer starts 50s, program controller is closed automatically.
3) take off feeding hopper 11, remove fixing feeding hopper supporting ring 10, scrape off unnecessary concrete mix and use spatula floating.After removing the concrete on the base of cylinder limit, vertically mention slump cone reposefully.The mentioning process and should complete in 5 ~ 10s of slump cone 8.From be charged to the whole process mentioning slump cone 8 and should complete in 120s.
4) after mentioning slump cone 8, fixing feeding hopper supporting ring 10 immediately on mobile column, concrete mix examination body peak after making supporting ring lower edge and collapsing is equal, from vertical rod, the lower limb of abutment ring reads scale (in units of mm), and this numerical value is the slump value of this concrete mix.
5) observe the height of liquid level in Water collecting tube, according to the color region at liquid level place, judge concrete water-retaining property.As the part concrete mix of liquid level in higher color region or cone is starched and aggregate exposure because flowing, 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 measures.As second time still there is this phenomenon, then represent that this mixture workability is bad, should give record for future reference.
7) measure and after recording the slump, water-retaining property, start program controller, observing the performance situation of concrete mix cone under effect of vibration, if cone is sunk gradually, represent that the glutinous poly-property of mixture is good; If cone is decayed, part is burst apart or occur segregation, then represent that the glutinous poly-property of concrete mix is poor.
The above is the preferred embodiment of the present invention, can not limit the interest field of the present invention with this.It should be pointed out that for those skilled in the art, technical scheme of the present invention is modified or equivalent replacement, do not depart from protection scope of the present invention.
