Description
Technical field
The utility model relates to a kind of analyzer measured for cellular concrete surface water-intake rate, belongs to concrete surface technical field.
Background technology
The method of testing of concrete surface water-intake rate has: 1) the overall weight method of concrete sample: leave test surfaces, all close with paraffin or cold coating for all the other 5, is represented by the change of quality before and after test specimen water suction; 2) core boring sampling (scene), leaves test surfaces, and its lap paraffin or cold coating are closed, and is represented by the change of quality before and after test specimen water suction; 3) card stone (KASTEN) pipe measures (in-site measurement), by fixing card stone pipe at concrete end face or side, injects water in card stone pipe inside, and record water scale calculates the water-intake rate of concrete surface over time.
In these methods especially on-the-spot water-intake rate measure in most convenient and direct method, being again the method for Non-Destructive Testing, is exactly card stone graduated cylinder method, and this instrument is termination is tubaeform and main body is the glassware of graduated cylinder with a scale (about 20cm is high).But this measurer can only measure the water-intake rate of concrete end face and side at present, the water-intake rate of concrete bottom can not be measured, the maximum deficiency of another one be strong wind or plasticine fixing loosely time can drop and break into pieces.
Summary of the invention
The purpose of this utility model is to provide the lossless scheme that a scene or indoor concrete absorptivity measure, simultaneously can not the impact of by wind and vibrations, and can measure in concrete end face, side and bottom surface, and reproducible.
The technical scheme completing foregoing invention task is, a kind of analyzer for the test of concrete surface water-intake rate, and be the water container that an impermeable material is formed, it is characterized in that, this container finish circumference is provided with edge; This internal tank is filled with absorbent material and quantitative water; This container finish packing material plastic sheeting seals.
In other words, structure of the present utility model is, the similar double dish of water container outer shape that impermeable material is formed, but adds edge, and internal diameter is at 50mm-110mm; External diameter 10mm larger than internal diameter.Material can be glass, waterproof paper or plastics.
The edge of oral area circumference, its internal diameter circle is opening, and form an entirety with the bottom of similar double dish, the thickness of container material is 0.5-1mm, external diameter 10mm larger than internal diameter;
The utility model is hollow structure, inner filling absorbent material and water.
The utility model is more optimized and technical scheme is more specifically:
Form the material of described water container: glass, waterproof paper and plastics, preferentially use plastics.
The edge of described water container scribbles hot melt adhesive layer;
Sealed plastic film in described hot melt adhesive layer surface pressure.
Internal tank fills absorbent material and water, requires water saturation but does not drip extension.
The absorbent material that internal tank is filled is selected from: PU polyfoam, acrylic absorbent resin, PVA water-absorbing resin, cotton, fiber, paper pulp or hydrogel can be wherein one or more, preferential employing acrylic absorbent resin and PVA water-absorbing resin.
The thickness of container is at 0.5-1.5mm, and the intensity according to material determines, precondition is not yielding, and the height of container is between 8-15mm.
Sealing means: the mechanical hot pressing sealing means adopting the packagings for foodstuff such as milk tea.
The utility model recommends following processing mode:
The processing of container: glass material is according to glass processing mode, and plastic material is according to method processing such as plastics extrusion moldings, and waterproof paper is processed according to the processing mode of Disposable paper cup.
The making of the utility model water-intake rate analyzer: enter a certain amount of absorbent material at container content, and the upper quantitative water of note, material different injection amount is different.In hot pressing mechanically to the hot sealing of water-intake rate device, check whether that sealing is intact, as intact, namely water-intake rate analyzer completes.
The use of the utility model water-intake rate analyzer:
Remove the greasy dirt of concrete surface and floating ash, weigh the initial weight (W of water-intake rate tester
0) (being accurate to 0.01g), tear diaphragm seal and the (W that weighs
1), be placed on by water-intake rate analyzer in concrete measuring surface, surrounding oiliness plasticine or glass cement are fixed, and after certain hour (t), remove fixture plasticine or glass cement, weigh the residuals weight (W of water-intake rate analyzer
2), be calculated as follows water-intake rate (P):
P=（W

Principle of work:
This measuring appliance to be satisfied water-based energy by absorbent material, when contacting with concrete surface, utilizing the water in the capillary force absorptiometry device of concrete pore, being measured the water-intake rate of concrete surface like this by the minimizing of measuring appliance moisture.
Advantage of the present utility model: the utility model compensate for the deficiency of card stone graduated cylinder method in prior art, normally can use when wind or vibrations; The water-intake rate in each face of concrete can be measured; Can be fixed on test surfaces easily.Through overtesting comparison, the result that the utility model measuring appliance and card stone pipe are measured is closely, reproducible.
