Abstract
The invention discloses a sealing material used for a concrete impermeability test. The sealing material comprises paraffin and one of cement, ore powder and coal ash, the ratio of paraffin to the cement, ore powder or coal ash is 1:0.2-0.5, and paraffin and cement, ore powder or coal ash are heated in a 50-80DEG C oven to melt, and are uniformly mixing. The sealing material is coated on the side surface of a sample, and an impermeability die sleeve is preheated to 50-80DEG C; and the sample is pressed in the die sleeve on a press, is slightly cooled, undergoes pressure release, and is provided with a concrete impermeability instrument for carrying out the impermeability test. The sealing material can guarantee the smooth implementation of the impermeability test of the sample, avoid the advanced water permeability of the edge of the sample, reduce the test cost, and improve the test efficiency.
Description
Technical field
The present invention relates to a kind of sealing material for concrete impermeability test.
Background technology
In building structure, bleeding of concrete directly has influence on use and the safety of buildings.Concrete is a kind of material of vesicular structure, and concrete impermeability refers to that liquid, gas etc. are stressed, partial potential or electric field action, the infiltration in concrete, the complexity that spreads or migrate; Concrete permeability resistance is one of long-term performance of concrete, by under the effect of pressure water, tests concrete impervious grade or seeps water and highly estimate different concrete impermeability differences.Concrete permeability resistance test is widely used in China's building, water conservancy each field.To some waterworks, the construction site of waterproof requirement is arranged, it uses concrete water resistant penetrating quality is very important material technology index.Need to adopt sealing material to be coated in concrete impermeability test sample to be packed into after the sample side surface in die sleeve and implement test, for a long time, the sealing material adopts paraffin and rosin mixture, butter and talcum powder mixture or bungee etc. mostly, its sealing effectiveness is not fine, often seeps water in advance from the sample edge in process of the test, causes test to be forced to stop, need again sample to be applied sealing material, waste time and energy thus, increased experimentation cost, reduced the efficient of test.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of sealing material for concrete impermeability test, utilize this sealing material to be coated on the sample side surface and can guarantee carrying out smoothly of impermeability test, avoid the infiltration in advance at sample edge, reduced experimentation cost, improved test efficiency.
For solving the problems of the technologies described above, the sealing material that the present invention is used for concrete impermeability test comprises a kind of of paraffin and breeze, flyash or cement, and in the ratio of 1:0.2～0.5, heats in 50～80 ℃ of baking ovens, makes it dissolve mix even.
Further, the slag micropowder after above-mentioned breeze can select blast furnace slag levigate.
The sealing material that is used for concrete impermeability test due to the present invention has adopted technique scheme, be that this sealing material comprises a kind of in paraffin and breeze, flyash or cement, and in the ratio of 1:0.2～0.5, heat in 50～80 ℃ of baking ovens, make it dissolve mix even.This sealing material is coated on the sample side surface can guarantees carrying out smoothly of sample impermeability test, avoided the infiltration in advance at sample edge, reduced experimentation cost, improved test efficiency.
Embodiment
The sealing material that the present invention is used for concrete impermeability test comprises a kind of of paraffin and breeze, flyash or cement, and in the ratio of 1:0.2～0.5, heats in 50～80 ℃ of baking ovens, makes it dissolve mix even.
Further, the slag micropowder after above-mentioned breeze can select blast furnace slag levigate has facilitated the making of this sealing material, has improved the viscosity of the paraffin of fusing; Simultaneously breeze also can adopt the testing station to retain the breeze of the discarded sample after March; Effectively saved the cost of manufacture of sealing material.
In this sealing material, the main chemical compositions of slag micropowder is SiO
2, Al
2O
3, CaO, MgO, Fe
2O
3, TiO
2And MnO
2Deng, it meets the S95 breeze of " slag micropowder that is used for cement and concrete " GB/T18046-2008 standard; Flyash is to receive the thin ash of catching the flue gas of coal-burning power plant after coal combustion, and its main chemical compositions is SiO
2, Al
2O
3, FeO, Fe
2O
3, CaO, TiO
2Deng, meet II level ash in " flyash that is used for cement and concrete " GB/T1596-2005 standard.
When concrete impermeability test, this sealing material is coated with rolls in specimen surface, simultaneously with the heating of impervious die sleeve, be loaded on impervious die sleeve and can implement test being coated with the sample that rolls.The sealing effectiveness of this sealing material is good, and simple to operate being convenient to implemented, and takes full advantage of discarded blast furnace slag, saved the sealing material cost.
Paraffin is placed in dissolves in 50～80 ℃ of baking ovens and that breeze, flyash or cement are placed in paraffin solution mix by 1:0.2～0.5 is even, the concrete sample of cleaning out is placed in the paraffin solution roller coating surface that is mixed with breeze, flyash or cement, with impervious die sleeve heating, after being loaded on impervious die sleeve, the sample that rolls carries out impermeability test with being coated with simultaneously.Through the contrast of for many years result of use, this sealing material than simple use paraffin to add rosin, bungee, flyash to add the sealing effectiveness of butter better.
Claims (2)
1. sealing material that is used for concrete impermeability test is characterized in that: described sealing material comprises a kind of in paraffin and breeze, flyash or cement, and in the ratio of 1:0.2～0.5, heats in 50～80 ℃ of baking ovens, makes it dissolve mix even.
2. the sealing material for concrete impermeability test according to claim 1 is characterized in that: described breeze is the slag micropowder of blast furnace slag after levigate.
