Abstract
The invention discloses a concrete impermeability test sealant prepared from illegal cooking oil and a preparation method of the sealant. The sealant is mainly applied to a concrete impermeability test and is used for sealing gaps between an impermeable concrete specimen and an impermeable cover die. The sealant is prepared from 20% to 25% of illegal cooking oil, 5% to 10% of asphalt and 65% to 75% of fillers. The method for preparing the sealant comprises the following steps: heating the illegal cooking oil and the asphalt together until the asphalt is molten, and then adding the fillers and evenly stirring so as to obtain an impermeable sealant. The defect that the sealing material is easy to deform is effectively overcome by adding the asphalt into the illegal cooking oil taken as the raw material, so that the sealing effect is improved. Thus, the quality of an impermeability test is improved.
Description
Technical field
The present invention relates to a kind of sealing material, mainly as concrete impermeability test, be especially applicable to the concrete sample of high anti-penetration grade.
Background technology
Concrete anti-permeability performance is one of important indicator of weighing concrete durability, the detection of concrete impermeability is according to GB/T 50082-2009 " Standard for test methods of longterm performance and durability of ordinary concrete " at present, this standard regulation detects concrete anti-permeability performance by pressurization infiltration method, make the concrete sample of anti-permeability performance for conical, while packing conical impervious module into, need to superscribe sealing material, the gap of water between concrete sample and impervious mould, ooze out and affect test effect to stop.
Adopting which kind of sealing material is the key of concrete impermeability test, also once adopted paraffin and rosin mixture as sealing material, operation easier is larger, and sealing effectiveness is bad, the mixtures such as butter and talcum powder that adopt seal more at present, though easy to operate, also exist some drawbacks, as under high pressure yielding and cause sealing effectiveness not good in it, affect the measurement result of impermeability test.
Along with improving constantly of the Concrete Structure Design standard, add that underground structure is more and more, also more and more darker, also more and more higher to the seepage resistance demand of concrete material, thereby the impervious sealing material of use can not meet requirement in the past.Often, because of the problem of sealing material, in the time that impermeability test is forced into high pressure, there is the seepage of sealing material layer, and can not reflect concrete impervious index, caused the failure of an experiment in test specimen more than P10.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of effective sealing material with sewer oil concrete batching impermeability test.Adopt sealing material operation simple, good sealing effect, has not only overcome the shortcoming of the sealing material in the past adopting and has realized the utilization of waste material of sewer oil, is applicable to promoting the use of.
A kind of concrete impermeability test sealing compound taking sewer oil as preparation of raw material of the present invention, it comprises following component and weight percent: sewer oil 20 ~ 25%, pitch 5 ~ 10%, stopping composition 65 ~ 75%.
Described stopping composition be talcum powder, light calcium carbonate, industrial by-products calcium sulphate powders, flyash wherein any.
The preparation method of described concrete impermeability test sealing compound, comprise the following steps: sewer oil is heated together with pitch, Heating temperature is 60 ~ 80 DEG C, or first sewer oil will be added after asphalt heating melting again, finally stopping composition is added and be uniformly mixed the also paste of cooling rear stiffization of formation, preserve stand-by as finished product.
The present invention has opened up the new purposes of sewer oil, and trench oil regeneration comprehensive utilization of resources is played to active effect.In addition, in sewer oil, add pitch effectively to improve the yielding shortcoming of sealing material, thereby improved sealing effectiveness, improved impermeability test quality.
Embodiment
Below in conjunction with specific embodiment, the invention will be further described.
Embodiment 1
Can be used for a sealing compound for concrete impermeability test, it comprises following component and part by weight thereof: sewer oil 20%, pitch 10%, talcum powder 70%.
Embodiment 2

Embodiment 5
Can be used for a sealing compound for concrete impermeability test, it comprises following component and part by weight thereof: sewer oil 21%, pitch 7%, talcum powder 72%.
Above-mentioned sealing compound needs to be heated to 40 ~ 50 DEG C in use, makes it to be under plastic state, is coated in the side of concrete impervious test piece, then test specimen is pressed in cover die.
Selecting with volume of stopping composition is important, and the specific surface area of filler particle should not be lower than 300m
2/ kg, heavy stopping composition, should improve volume.Talcum powder is conventional stopping composition.Mainly taking road bitumen as main, according to SH/T 0522-2010 " bi tumenf orr oad ", bi tumenf orr oad is divided into No. 200, No. 180, No. 140, No. 100, No. 60 by penetration degree, preferentially uses the pitch that penetration degree is larger in the market, so that operation.
Be more than the preferred embodiments of the present invention, it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also make some improvement, these improve and also should be considered as protection scope of the present invention.
