Abstract
The invention relates to a sealant for a concrete impermeability test piece, which belongs to the technical field of building materials. The sealant for the concrete impermeability test piece consists of calcium base grease, talcum powder, bentonite, and kaolin according to the weight proportion of 1 to 0.25-0.8 to 0.15-0.4 to 0.15-0.4. Raw materials are fully stirred evenly according to the proportion and prepared into a paste form, then is evenly coated on side elevations of the concrete impermeability test piece, and the concrete impermeability test piece is loaded into an impermeability test mold and is subject to a bulge test by a cement impermeability tester. The sealant has the advantages that the sealant adopts a cold coating method to coat, has safe and convenient use and simple operation, ensures the sealing quality of the concrete impermeability test piece, and improves the success ratio and work efficiency of impermeability tests.
Description
Technical field
The present invention relates to a kind of concrete impervious test piece sealant, belong to building material technical field.
Background technology
In the building construction process, often use the water-proof concrete of different grades, concrete permeability resistance is an important indicator estimating its endurance quality, obtains by concrete impermeability test.Therefore sealing impervious test piece becomes a main action.All adopt paraffin as sealing material in the traditional method, at first must be with impervious die trial preheating, concrete impervious test piece rolls on the paraffin of heat fused, put into impervious examination film phonograph seal then after, suppress through Anti-leakage instrument.Because the paraffin hot melting temperature is wayward, influenced by ambient temperature in addition, this process spended time is longer, and operation is extremely inconvenient, and is easily scalded; In addition, sealing material is difficult for smearing evenly, and it is poorly sealed the test specimen periphery very easily to occur, and the situation of leaking causes the concrete impermeability test failure, must change test specimen and carry out seal operation and test again, causes material, the energy and waste of time.Recently, people also adopt quicklime grease and talcous mixture to seal, and impervious effect makes moderate progress, but still not ideal enough.
Summary of the invention
The object of the present invention is to provide a kind of concrete impervious test piece sealant, with solve the conventional seals material use inconvenient, problem such as the impermeability test one-time success rate is low.
The technical solution used in the present invention is as follows:
Concrete impervious test piece sealant of the present invention is made up of by weight the ratio of 1:0.25～0.8:0.15～0.4:0.15～0.4 quicklime grease, talcum powder, wilkinite and kaolin.
Described concrete impervious test piece sealant preferably consists of, and is made up of by weight the ratio of 1:0.4～0.6:0.2～0.3:0.2～0.3 quicklime grease, talcum powder, wilkinite and kaolin.
Described concrete impervious test piece sealant, more excellent consists of, and is made up of by weight the ratio of 1:0.5:0.25:0.25 quicklime grease, talcum powder, wilkinite and kaolin.
During use, at first quicklime grease, talcum powder and wilkinite are stirred in proportion, make paste, evenly spread upon the concrete impervious test piece side elevation with scoop then, pack in the impervious die trial, beat, cause test specimen to flush with the die trial edge is consistent with gavel, impervious test piece is packed in the concrete impervious instrument, can carry out bulge test.
Concrete impervious test piece sealant of the present invention mainly is oilness and a viscosity of utilizing quicklime grease; Talcous oilness helps fluidity; Bentonitic water-swelling, cohesiveness and viscous thixotropy; Kaolinic viscosity, associativity and plasticity-.Sealing compound of the present invention has certain viscosity and flexibility, therefore is easy to spread upon the concrete impervious test piece side elevation; Owing to have water-swelling, concrete impervious test piece sealant can expand immediately behind the chance water, stops up the micro gap between test specimen and the die trial; Owing to have flexibility, plasticity-, fillibility, oilness and help fluidity, the big slit of the die trial of test specimen can being packed into is carried out filling, thereby is guaranteed the sealing property of its concrete sample under the hydraulic pressure effect.
The invention has the beneficial effects as follows:
(1) compare with traditional paraffin sealing compound, sealing compound of the present invention can the directly cold surface that is applied to test specimen, does not need heat before the use, has saved the energy, and has avoided scald, and is safe and convenient to use;
(2) sealing compound excellent property of the present invention is simple to operate, is easy to coating, and the impermeability test of once packing into success ratio height had both guaranteed the quality of sealing impervious test piece in concrete, had saved the operating time again, had improved working efficiency.

Test case
1 testing method is as follows:
(1) choose 18 with a collection of test specimen, maintenance is taken out from standard curing room to testing the day before yesterday, and the surface is dried, and the failure handles again to end face;
(2) test specimen is divided into 3 groups at random, 6 every group, operates by identical staff.
Group 1 sealing compound that will only contain paraffin is applied in the test specimen surface, group 2 is smeared and is contained quicklime grease and talcous sealing compound, and group 3 sealing compounds of smearing embodiment 4 guarantee that the test specimen side forms the sealing ply of 1.5mm, test specimen is packed in the mould by standard, and write down this process and respectively organize the used time.
(3) test specimen is pressurizeed, observe the infiltration situation at test specimen edge at any time, the destruction number of sealed test piece sees Table 1 when writing down pressure respectively and being 0.6MPa, 0.8MPa and 1.2MPa.
2 test results
(1) respectively organizes close Encapsulation Moulds time ratio: about 2 hours of 1 each test specimen time spent of group, group 2 and 3 10～12 minutes each test specimen times spent of group.
(2) the test specimen sealing effectiveness relatively.
Table 1 sealing compound sealing effectiveness detects
As shown in Table 1, in the pressure testing scope of 0.6～1.2MPa, the situation of edge infiltration does not all appear in the impervious test piece of smearing sealing compound of the present invention, and success ratio is 100%, and smears the group 1 and group 2 test specimens of other sealing compounds, increases with pressure, the infiltration phenomenon then occurs.
Again 3 kinds of sealing compounds are carried out repeatedly parallel test relatively, the result is basic identical with table 1.
In summary, sealing compound excellent property of the present invention is easy to coating, has significantly improved the success ratio of impermeability test, has saved the working hour, increases work efficiency 2～3 times, and has ensured operator's safety.
