Abstract
The utility model discloses a simple and easy detection device of concrete porosity of permeating water, including the the gas content of the concrete apparatus, the the gas content of the concrete apparatus is connected with a gas holder that the volume is certain, the gas holder is linked together through pipeline and test specimen tube, the pipeline is equipped with the control valve, the gas holder is equipped with the manometer, the utility model has the advantages of: the concrete porosity of can the short -term test permeating water, simple structure, convenient to use, the error is less, and is high -efficient quick.
Description
Technical field
The utility model relates to a kind of pervious concrete porosity simple detection device, and specifically a kind of laboratory and workyard detect the simple and easy of pervious concrete porosity fast, belongs to pervious concrete porosity detection device field.
Background technology
Pervious concrete also known as cellular concrete, non-fine concrete, permeable terrace. Being a kind of porous light concrete become by aggregate, cement and water mixing, it containing fine aggregate, does not mutually bond and form the equally distributed polynuclear plane in hole by coarse aggregate Surface coating skim grout, therefore has ventilative, permeable and lightweight feature. Its functional performance depends primarily on the vesicular structure characteristic of its uniqueness, therefore determine pervious concrete works quality it is crucial that porosity. The existing measuring method of pervious concrete porosity is mainly divided into volumetric method and weighting method, and volumetric method measures and uses U.S. CoreLok vacuum density instrument, and this kind of method is measured accurately, but operating process is comparatively complicated; Weighting method adopts hydrostatic electronic balance to measure, and this kind of method is simple to operate, but can only harden delayed detection at pervious concrete. Above two kinds of methods all cannot be mixed the scene of conjunction again and pervious concrete porosity be detected. In recent years, but the range of application of pervious concrete is more and more extensive. Therefore use the range of application of permeable concrete more and more wider. When therefore using permeable concrete material to construct, newly mix material Site Detection the quality of pervious concrete material structure thing is particularly important.
Practical novel content
In order to solve the porosity problem of Site Detection pervious concrete, the utility model devises a kind of pervious concrete porosity simple detection device, can detect pervious concrete porosity fast, and structure is simple, it may also be useful to convenient, error is less, efficiently fast.
The technical solution of the utility model is:
A kind of pervious concrete porosity simple detection device, comprising concrete 's air-containing determinator, described concrete 's air-containing determinator is connected with the certain gas-holder of a volume, and described gas-holder is connected with sample cylinder by pipeline, described pipeline is provided with control valve, and described gas-holder is provided with tensimeter.
The principle of concrete 's air-containing determinator is P1 �� V1=P2 �� V2, determinator is installed the certain gas-holder of a volume, it is then V1, there is an exhaust-duct that can control gas-holder bottom in sample cylinder, inflate in gas-holder when testing the voidage of pervious concrete, pressure is made to reach certain value (about 0.2MPa), it is possible to think the P1 that now manometric indicating value is in law. When opening the valve of bleed passage, void volume in sample cylinder is connected the V2 just becoming in law with volume of gas storage tank, and the tensimeter indicating value therefore declined the also corresponding P2 becoming in law, this is exactly the voidage of pervious concrete or the test philosophy of normal concrete air content.
The utility model utilizes normal concrete gas content, adopts the detection method of not water filling, fast the voidage of detection pervious concrete. Test of many times result shows, the detected value that this method obtains error compared with Design Theory value is less, and this method is simple to operate.
Further, described gas-holder also has aerator pump to be connected.
Measure that air content cylinder should carry out before pervious concrete voidage rate is fixed, with determine corresponding to different voidages tensimeter read. It is when known V2 that mensuration concrete 's air-containing rate works surely, finds out the relation of corresponding P2; The voidage measuring pervious concrete is then in known P2 situation, finds out the test of corresponding V2. The result that percent of pass is fixed, adjusts accordingly by air content dial plate, provides convenience for measuring pervious concrete voidage later.
The utility model has the advantage of: proving through the work of a large amount of laboratory test, this device is simple to operate, easily measuring the porosity of pervious concrete, the pervious concrete porosity measured is comparatively accurate; Achieve the simple detection just mixing pervious concrete voidage, be conducive to the design of pervious concrete proportioning.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Hereinafter preferred embodiment of the present utility model is described, it will be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and is not used in restriction the utility model.
Embodiment 1
As shown in Figure 1, a kind of pervious concrete porosity simple detection device, comprise concrete 's air-containing determinator 1, for the conventional instrument in this area, described concrete 's air-containing determinator 1 is connected with the certain gas-holder 2 of a volume, described gas-holder 2 is connected with airtight sample cylinder 3 by pipeline, and described pipeline is provided with control valve 4, and described gas-holder 2 is provided with tensimeter 5. Described gas-holder 2 is also connected with aerator pump 6.
The principle of concrete 's air-containing determinator is P1 �� V1=P2 �� V2, determinator is installed the certain gas-holder of a volume, it is then V1, there is an exhaust-duct that can control gas-holder bottom in sample cylinder, inflate in gas-holder when testing the voidage of pervious concrete, pressure is made to reach certain value (about 0.2MPa), it is possible to think the P1 that now manometric indicating value is in law. When opening the valve of bleed passage, void volume in sample cylinder is connected the V2 just becoming in law with volume of gas storage tank, and the tensimeter indicating value therefore declined the also corresponding P2 becoming in law, this is exactly the voidage of pervious concrete or the test philosophy of normal concrete air content.
The utility model utilizes normal concrete gas content, adopts the detection method of not water filling, fast the voidage of detection pervious concrete. Test of many times result shows, the detected value that this method obtains error compared with Design Theory value is less, and this method is simple to operate.
