Abstract
Embodiments provide a kind of concrete NDT device, it is characterized in that, comprising: container, electric heating stirrer, dog-house; Wherein, dog-house is positioned at the top of container, communicates with container, and after dropping into material by dog-house, material directly can put into internal tank; Electric heating stirrer is connected with container is integrated.
Description
Technical field
The present invention relates to concrete field, particularly a kind of concrete NDT device.
Technical background
In the standard criterion that existing cement, flyash and ground slag powder perform; as GB175-2007 " common portland cement ", GB/T18046-2008 " GBFS in cement and concrete ", GB/T1596-2005 " flyash in cement and concrete "; all not to the objectionable impurities regulation method of inspection existed and index request; and the existence encountered in the concrete production process of reality because of objectionable impurities causes concrete mix to discharge gas, concrete volume abnormal expansion in the process that hydration reaction occurs.
The P42 in " problem flyash causes the analysis of causes of concrete abnormal occurrence " literary composition that is entitled as that " flyash " third phase Wu Danhong in 2009 writes makes referrals to: the flyash that takes a morsel is placed in container, add suitable quantity of water to stir, stir and initially have slight taste, stir after one minute, pungent taste is denseer.And grey Starch Level has oil slick to occur.
Describe in " the concrete bubbling crash analysis caused by flyash together " civilian P58 that volume the 10th phase in " Zhejiang building " October the 24th in 2007 Huang resembles Hangzhoupro, Ye Qing writes: carry out simulation test according to above analysis: the Binder Materials (cement, flyash) in concrete is put into the beaker that water or alkaline solution are housed, in the baking oven of 65 DEG C, place 30min, observe the situation of change of solution in beaker.
Summary of the invention
The embodiment of the present invention provides a kind of concrete NDT device, for detecting the objectionable impurities in concrete gel material.
A kind of concrete NDT device that the embodiment of the present invention provides, comprising: container, electric heating stirrer, dog-house; Wherein,
Dog-house is positioned at the top of container, communicates with container, and after dropping into material by dog-house, material directly can put into internal tank;
Electric heating stirrer is connected with container is integrated.
Wherein, described electric heating stirrer has a controller, for regulating stirring intensity and heat time.
Wherein, described container is connected by dog-house valve with between dog-house, when dog-house valve open, delivers material by dog-house in container; When dog-house valve closing, no thoroughfare, and dog-house delivers material in container.
Wherein, described container bottom is provided with a blowoff valve further, for getting rid of all kinds of waste materials detected.
Wherein, described device comprises further: pH value tester is connected with container by the pipeline that is positioned at container top, for detecting the pH value of the gas being flowed to pH value tester by pipeline.
Utilize the embodiment of the present invention to provide a kind of concrete NDT device, may be used for the objectionable impurities in Aulomatizeted Detect concrete gel material, convenient operation.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of concrete NDT device in the embodiment of the present invention.
Embodiment
For making the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, the present invention is described in further detail.
Figure 1 shows that the structural representation of a kind of concrete NDT device in the embodiment of the present invention.As shown in Figure 1, this device comprises container, electric heating stirrer, dog-house.Wherein, dog-house is positioned at the top of container, communicates with container, is dropped into after material by dog-house, can see into internal tank.Electric heating stirrer is connected with container is integrated.
In an embodiment of the present invention, electric heating stirrer has a controller, can regulate stirring intensity and heat time, when reaching setup parameter, automatically stops.
In an embodiment of the present invention, be connected by dog-house valve between container with dog-house, when dog-house valve open, material can be delivered by dog-house in container; When dog-house valve closing, no thoroughfare, and dog-house delivers material in container.
In an embodiment of the present invention, container bottom is also provided with a blowoff valve, for getting rid of all kinds of waste materials detected.
In an embodiment of the present invention, this device can further include pH value tester, and pH value tester is connected with container by the pipeline that is positioned at container top, and the gas produced in such container flows to pH value tester by pipeline.
Material to be detected and strong base solution (as NaOH) are successively thrown in container by dog-house, start electric heating stirrer, heat and stir the potpourri in container.Controller regulates stirring intensity and heat time, when reaching setup parameter, automatically stops.The gas produced enters pH value tester by pipeline, and pH value tester detects the pH value exporting and generate gas.
In an embodiment of the present invention, sampler can be adopted from the insertion suitable for reading of Binder Materials transport vehicle, and extract the concrete sample of surperficial at least below the 50cm of distance, sampling spot position is no less than three, accumulative sampling amount is no less than 5kg, mixes rear as detected object.
In an embodiment of the present invention, first throw in 100ml by dog-house toward container, NaOH 5g, utilize electric heating stirrer to be heated to 60 ~ 70 DEG C, after load weighted flyash sample 50g is put in container by dog-house, utilize electric heating stirrer to be stirred to flyash and all disperse.The gas pH value produced in container detected according to PH value detector, the objectionable impurities in concrete gel material can be inferred further.Such as, if PH value detector detects that the gas pH value produced in container is alkalescence, the objectionable impurities in deducibility concrete gel material is NH4
+(NH4
++ OH
-=NH
3+ H
2o).If PH value detector detects that the gas pH value produced in container is for neutral, then the objectionable impurities in deducibility concrete gel material is aluminium (AL) (2A1+2H
20+20H
-=2AlO
2 -+ 3H
2).
The concrete NDT device utilizing the embodiment of the present invention to provide, can detect concrete raw material, and as flyash, cement, ground slag powder and silicon ash etc., convenient operation, achieves Aulomatizeted Detect.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement etc., all should be included within protection scope of the present invention.
