The measuring device is characterized in that the lower end face of the cylinder is provided with a removable sealed bottom cover while the upper end face of the cylinder is equipped with a water inlet. The water inlet is provided with a sealing device and a measuring device. The sealing device is arranged on the water inlet when sampling, and removed when injecting water. During measuring, the water inlet is equipped with the measuring device.
Description
Technical field
The utility model relates to a kind of device of measuring cement concrete surface mortar air content.
Background technology
Gas content is an important indicator of estimating cement concrete performance, and the gas content of cement concrete surface screed has more influence to concrete hardening capacity.At present the method for mensuration cement concrete gas content commonly used has two kinds of volumetric method and pressure methods.The pressure method is in the most frequently used method of field survey fresh concrete air content.This method changes the fresh concrete volume by given pressure, supposes that the change value of volume is caused by the air compression fully, calculates air content by Boyle's law.Because cement concrete surface mortar limited amount and difficult the extraction are difficult to satisfy the mortar consumption of pressure method defined.Therefore, the pressure method can't be measured the gas content of cement concrete surface mortar.Volumetric method is according to the volume that contains the fresh concrete volume of air and removed air by stirring in water has been made comparisons.The used instrument of volumetric method is popularized abroad, but does not domesticly still have widespread production and an application, and existing laboratory is a complex structure with the shortcoming of volumetric method determining instrument, waste time and energy during operation, and can not actual response concrete cement mortar virtual condition.
Summary of the invention
The utility model provides a kind of easy device of the mensuration cement concrete surface mortar air content based on volumetric method, can draw gas content by shirtsleeve operation, and it is more time saving and energy saving to compare original volumetric method analyzer.
For reaching above purpose, the utility model takes following technical scheme to be achieved:
A kind of determinator of cement concrete surface mortar air content, comprise cylindrical shell and rabbling mechanism, this rabbling mechanism is arranged on cylindrical shell top and extends in the cylindrical shell, it is characterized in that, the lower surface of described cylindrical shell is provided with removable sealing bottom, upper surface one side of cylindrical shell is provided with water filling port, and described water filling port is provided with closing device and measurement mechanism; When sampling, closing device is set on the water filling port; When water filling, take off this closing device; When measuring, measurement mechanism is set on the water filling port.
In the such scheme, described closing device is a turncap; Measurement mechanism is the connection turncap of a band graduated tube.Described rabbling mechanism comprises spiral stirrer paddle, and it is loaded on the shaft, and this shaft is by being arranged on a handwheel on the external top of center support frame coupling tunnel, cylindrical shell upper surface.
The utility model has the advantages that, adopt on-site sampling cement concrete surface screed,, drive the shaft rotation, the sand-cement slurry internal gas is overflowed from water by rotating handwheel by water filling port water filling in cylindrical shell.By connection turncap, observe the interior liquid level decline of graduated tube and just can calculate gas content at water filling port mounting strap graduated tube.This device is lightly portable, is fit to the working-yard and uses, and can take a sample and measure the gas content of on-the-spot cement concrete surface mortar easily, makes test result and virtual condition more approaching.Improve the deficiency of experimental test in the conventional chamber, the actual performance of reaction material directly perceived, correct guidance engineering construction in time.
Description of drawings
Fig. 1 is a sectional view of the present utility model.
Among the figure; 1. bottom; 2. spiral stirrer paddle; 3. cylindrical shell; 4. shaft; 5. handwheel; 6. shaft bracing frame; 7. water filling port; 8. SOC.HD. cap screw; 9. waterproof washer; 10. turncap; 11. the connection turncap of band graduated tube.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and example.
As shown in Figure 1, a kind of determinator of cement concrete surface mortar air content will have the shaft 4 of spiral stirrer paddle 2, be fixed on the cylindrical shell 3 by bracing frame 6.The outer end of shaft 4 is fixing by handwheel 5, and cylindrical shell 3 lower surfaces are sealed by SOC.HD. cap screw 8 and waterproof washer 9 by bottom 1.Turncap 10 is tightened on the water filling port 7, cylindrical shell 3 is placed upside down on the level ground, handwheel 5 is contacted with ground, unload the SOC.HD. cap screw 8 that connects bottom 1 and cylindrical shell 3, bottom 1 is taken off be put in one side.At the construction field (site) the cement concrete surface screed is taken a sample, and inject in the cylindrical shell 3, bottom 1 is built, screw SOC.HD. cap screw 8, cylindrical shell 3 is just put again, handwheel 5 up.
Turncap on the water filling port 7 10 is taken off, by the water filling in cylindrical shell 3 of water filling port 7 places, after current overflow, will be with the connection turncap 11 of graduated tube to be threaded onto on the water filling port 7, continue water filling by funnel by graduated tube in cylindrical shell 3, arriving the graduated tube upper end until liquid level has the scale place.
After determinator left standstill one minute, note the liquid level H in the graduated tube
1,, the tested mortar in the cylindrical shell 3 is stirred along a direction rotation hand wheel 5, gas in the tested mortar is overflowed from the graduated tube of turncap 11, and at this moment liquid level can descend thereupon in the graduated tube, when liquid level no longer descends, stop to stir, note the liquid level H in graduated tube this moment
2, according to two liquid level difference H in the graduated tube before and after stirring
1-H
2Can calculate the gas content of cement concrete mortar specimen in the cylindrical shell 3.
