Abstract
The invention discloses a kind of take sewer oil as concrete impermeability test sealing compound of preparation of raw material and preparation method thereof, sealing cream is mainly used in concrete impermeability test, for the gap between blocking concrete impervious test piece and impervious cover die, it comprises sewer oil 20 ~ 25%, pitch 5 ~ 10%, stopping composition 65 ~ 75%.During preparation, be that sewer oil and pitch are heated to asphalt melting jointly, then stopping composition added and mixes thoroughly, be a kind of impervious sealing compound.The present invention is raw material with sewer oil, adds pitch and effectively improves the yielding shortcoming of sealing material, thus improve sealing effectiveness, improve impermeability test quality in sewer oil.
Description
Technical field
The present invention relates to a kind of sealing material, be mainly used 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 weighing concrete durability, the detection of current concrete impermeability is according to GB/T50082-2009 " Standard for test methods of longterm performance and durability of ordinary concrete ", this standard regulation pressurization infiltration method detects concrete anti-permeability performance, make the concrete sample of anti-permeability performance for conical, need to superscribe sealing material when loading conical impervious module, affect test effect to stop water to ooze out from the gap between concrete sample and impervious mould.
Which kind of sealing material is adopted to be the key of concrete impermeability test, also once adopted paraffin and rosin blend as sealing material, operation easier is larger, and sealing effectiveness is bad, the mixture such as butter and talcum powder that adopts seals more at present, though easy to operate, also there are some drawbacks, as under high pressure yielding in it and cause sealing effectiveness not good, have impact on the measurement result of impermeability test.
Along with improving constantly of the Concrete Structure Design standard, add that underground structure gets more and more, also more and more darker, also more and more higher to the seepage resistance demand of concrete material, the impervious sealing material of thus passing by can not meet requirement.Often because of the problem of sealing material, there is the seepage of sealing material layer when impermeability test is forced into high pressure, and concrete impervious index can not have been reflected, result in the failure of an experiment in the test specimen of more than P10.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of with the effective sealing material of sewer oil concrete batching impermeability test.Adopt sealing material operation simple, good sealing effect, not only overcome the shortcoming of the sealing material in the past adopted and achieve the utilization of waste material of sewer oil, being applicable to promoting the use of.
Of the present invention a kind of take sewer oil as the concrete impermeability test sealing compound of preparation of raw material, 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 one.
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 add sewer oil again by after asphalt heating melting, finally stopping composition is added and be uniformly mixed and cool the rear paste forming stiffization, namely preserve stand-by as finished product.
The present invention opens the novelty teabag of sewer oil, plays active effect to trench oil regeneration comprehensive utilization of resources.In addition, in sewer oil, add pitch effectively improve the yielding shortcoming of sealing material, thus improve sealing effectiveness, improve impermeability test quality.
Embodiment
Below in conjunction with specific embodiment, the invention will be further described.
Embodiment 1

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 under in plastic state, is coated in the side of concrete impervious test piece, then is pressed in cover die by test specimen.
Selecting with addition ratio of stopping composition is more important, and the specific surface area of filler particle should not lower than 300m
2/ kg, heavy stopping composition, should improve volume.Talcum powder is conventional stopping composition.Main based on road bitumen in the market, according to SH/T0522-2010 " bi tumenf orr oad ", bi tumenf orr oad is divided into No. 200, No. 180, No. 140, No. 100, No. 60 by penetration degree, the pitch that preferential use penetration degree is larger, 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 improvement also should be considered as protection scope of the present invention.
