Abstract
The invention discloses an apparatus of high pressure collecting hardened concrete solution in hole which is consisted of a cylinder body, a piston moving up-and -down in the cylinder body, under the piston, sealing gasket cooperating hermetically with the cylinder body, a brace table under the cylinder body, and a endless displacement tank on the edge of the cylinder body formed by which and the brace table, which linking to solution in hole collecting device by tubing guide. The cylinder body and the piston can be cylinder. Through the method, all ion in hardened concrete slurry holes can be obtained directly, acquiring practical concentration of ion in hardened concrete slurry holes, as for hardened concrete with low water cement ratio or which has a long term, it can correctly analyze and component and concentration of ion in solution in hole as well. The technical program has simple operation and low cost.
Description
Technical field
The present invention relates to the concrete structure material field, particularly collect the device of hardened concrete hole solution.
Background technology
The destruction of reinforced concrete structure mainly is by due to the steel bar corrosion; The intrusion of carbonization and villaumite then is the main cause of steel bar corrosion.Steel bar corrosion is that reinforcing bar is in the galvanochemistry proterties in the concrete hole solution.Liquid phase ingredient in the cement slurry is commonly used to infer its solid phase composition when different hydration age.Be accompanied by the aquation of cement, formed mineral are as C-S-H gel and Ca (OH)
2Deng constantly dissolving and separating out, finally in this solution, reach balance, i.e. the various ion concentration differences in the hole solution, the basicity difference of hole solution when different hydration ages are to the difference that influences of hydrated cementitious.
At present, generally the hole solution acquisition methods of Cai Yonging mostly is leaching, when its ultimate principle is a concrete hydrating to certain length of time, sampling, levigate, adopt a certain amount of water with the soluble ion stripping in the maturing, analyze in the obtained aqueous solution various from composition and concentration.
Use leaching can't obtain water-fast ion in the maturing slurry hole, thereby test gained ion component is inaccurate, in addition, owing to the moisture in the hardened paste hole can not be got rid of fully, thereby adopt leaching only to reflect stripping rear solution intermediate ion concentration, and can not obtain ion concentration in the actual concrete hole solution, especially for low water-cement ratio or long-term maturing, the ion concentration analysis result in the concrete hole solution can produce than mistake.
Summary of the invention
The objective of the invention is for overcoming the existing methods weak point, provide a kind of high pressure to extract the device of hardened concrete hole solution.Adopt this device, can obtain the solution in the maturing hole, thereby reflect the composition of the inner contained ion of concrete pore and the time of day of concentration more exactly.
For achieving the above object, the present invention is achieved in that
A kind of device of high pressure collecting hardened concrete hole solution, comprise a cylinder body and the piston that can in cylinder body, move up and down, below described piston, be provided with the gasket seal that is sealed and matched with described cylinder body, described cylinder body below is provided with a brace table, described cylinder body and described brace table form a circular row liquid bath at described cylinder diameter edge, and described circular row liquid bath links to each other with the hole solution gathering-device by mozzle.Described cylinder body and described piston can be right cylinders.
Preferable, also be provided with and the identical cylinder body bracing means of the outside surface of described cylinder body in the described cylinder body outside.
Preferable, on described cylinder body bracing means, be arranged with two handles.
Preferable, below described brace table, be provided with base.
Preferable, described hole solution gathering-device is a syringe.
Preferable, the material of described cylinder body and described piston is the NI-CR-MO alloys steel.
Preferable, the material of described cylinder body bracing means is a carbon steel.
Preferable, the material of described gasket seal is a teflon.
Can obtain all ions in the maturing slurry pore solution by technical scheme of the present invention, thereby test gained ion component is more accurate.Owing to can directly obtain the solution in the maturing slurry hole, so can obtain the actual concentration of concrete pore effects of ion.For the amount of solution in hole maturing less low water-cement ratio or long-term, also can analyze ion component and concentration in the hole solution accurately; This technical scheme is easy and simple to handle and with low cost.

Embodiment
Further specify the present invention below in conjunction with drawings and Examples.
As shown in Figure 1, a kind of device of high pressure collecting hardened concrete hole solution, comprise a cylinder body 5 and the piston 7 that can in cylinder body 5, move up and down, below described piston 7, be provided with the gasket seal 4 that is sealed and matched with described cylinder body, described cylinder body 5 belows are provided with a brace table 2, described cylinder body 5 forms a circular row liquid bath 8 with described brace table 2 at described cylinder body 5 internal diameter edges, and described circular row liquid bath 8 links to each other with hole solution gathering-device-syringe 10 by mozzle 11.Below described brace table 2, be provided with base 1.Also be provided with and the identical cylinder body bracing means 6 of the outside surface of described cylinder body in described cylinder body 5 outsides.On described cylinder body bracing means 5, be arranged with two handles 9.Wherein, described cylinder body 5 is right cylinder with described piston 7.The material of described cylinder body 5 and described piston 7 is the NI-CR-MO alloys steel.The material of described cylinder body bracing means 5 is a carbon steel.The material of described gasket seal 4 is a teflon.
During use, take out piston 7 earlier, then sample 3 is put into cylinder body 5, put into gasket seal 4 on the top of sample 3, put into piston 7 again, load with the hydraulic type pressing machine then, the speed with suitable compressive strength 2.8MPa/s on piston 7 is loaded on maximum pressure 550Mpa, keeps a few minutes when reaching maximum pressure.At this moment the hole solution that is extruded by high pressure can flow out along sump pit 8, and in order better to obtain hole solution, at this moment available syringe 10 is extracted hole solution out.Can obtain more hole solution with slow relatively pressing speed.If once do not have to obtain predetermined hole solution quantity, pressure can be reduced to about 350MPa, then pressure is added to 550MPa gradually, obtain a certain amount of hole solution once more.Load in the actual experiment and can obtain 7-10ml solution four times, when extracting the quantity not sufficient 3ml of solution, increase the loading number of times and extract solution as much as possible.After extraction finishes, liquid drawing device 10 is taken off from leakage fluid dram, the residual air of discharging in the liquid drawing device 10 also seals liquid drawing device 10, in order to avoid the carbonization of solution.Pull handle 9 subsequently, and bracing means 6 is pulled out, and then cylinder body 5 taken off together with piston 7, promote piston 7, and sample 3 is released, and clean cylinder body 5 then, piston 7 and brace table 2, and package unit re-assemblied.
