Embodiment
General assembly structural representation as shown in Figure 1, is made up of base 1, slump cone 2, column with holes 3, scale column 4, setscrew nut 5, fixing feeding hopper supporting ring 6.
Rectangular interspersed bolt structure schematic diagram as shown in Figure 3, is made up of rectangular interspersed screw 7 and wing nut 8.
1) first soak slump cone, feeding hopper, Water collecting tube barrel and bottom surface and other apparatus with wet cloth, require wetting and without open fire.Base is placed on solid surface level, with long spiro nail, slump cone and base is fixed together, feeding hopper laid by slump cone.
2) divided by mixed concrete mixture sample scuppit 3 layers to load equably in cylinder on request, after making tamping every layer of specimen height be cylinder high about 1/3.Every layer plugs and pounds 25 times with tamper.Should be carried out to center by periphery along the hand of spiral when plugging and pounding, plug and pound at every turn and should be uniformly distributed on cross section.When plugging and pounding the concrete sample on a limit, tamper can tilt a little; When plugging and pounding bottom, tamper should run through entire depth; When plugging and pounding the second layer and top layer, tamper should insert the surface of this layer to lower one deck.During pouring top layer, concrete mix should be filled with to feeding hopper 2/3 place, after top layer plugs and pounds, scrape off unnecessary concrete mix and use spatula floating.
3), after removing the concrete on the base of cylinder limit, vertically slump cone is mentioned reposefully.The raising process of slump cone should complete in 5 ~ 10s.From be charged to the whole process mentioning slump cone and should complete in 150s.
4) after mentioning slump cone, slump scale immediately on mobile column, concrete mix examination body peak after making scale 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 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 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, impact gently with the mixture pyramid side that tamper is collapsing, if cone is sunk gradually, representing that the glutinous poly-property of mixture is good; If cone is decayed, part is burst apart or occur segregation, namely glutinous poly-property is poor.
8) when the slump recording mixture does not reach requirement, water cement ratio can be kept constant, increase by cement and the water of 5% or 10%; When the slump is excessive, sand coarse aggregate ratio can be kept constant, take the circumstances into consideration the consumption increasing sand and stone; As glutinous poly-property or poor water retention property, then need suitably to adjust sand coarse aggregate ratio.After each adjustment, mix is even as early as possible, re-starts the slump and measures.
The above is preferred implementation of the present utility model, can not limit the interest field of the utility model with this.It should be pointed out that for those skilled in the art, the technical solution of the utility model is modified or equivalent replacement, do not depart from protection domain of the present utility model.
