Description
Technical field
The present invention relates to foam concrete testing field, and in particular to a kind of test side of foam concrete foamy body
Method.
Background technology
China's building thermal insulation material demand is very big, and foam concrete exists as lightweight, nontoxic, durable heat preserving and insulating material
Extensive use is had been obtained in building heat preservation in recent years.Foam concrete is mainly formed by cement slurry and foam stirring,
In addition to technique, the performance of most significantly foam is influenced on concrete performance.During foam concrete slurry hardens, bubble
Foam plays the role of supporting cement slurry, therefore the intensity of foam has a great influence foam concrete performance, and foam mixes at present
The method that foamy body is not tested in solidifying soil field.
It is less with the relevant document of foaming properties test in foam concrete at present, and be all from foam stability test into
Hand, such as patent：A kind of measuring device of foamable composition multiplying power and foam stability, patent No. CN201620079632.6；Bubble
The application and method that foam stability is improved, patent No. CN201280034176.8；Deng.
And for the Problems Existing of arch fill, document《Foaming properties overall merit experimental design》(experimental technique and pipe
Reason, 2017) in the foamability of oil field foam, stability, take shut-off capacity in sand (rock) ability, porous media
Performance test methods are described, but without reference to the experimental design tested foamy body,《Foaming parameter is to upper pulp foam
The influence of performance》(cotton textile technology, 2017),《Foaming agent and foam concrete Review Study》Carried in (value engineering, 2017)
And influences of the foaming properties to foam concrete, but foam test method is not done and is deeply probed into.
The present invention utilizes homemade Simplified Test Equipment, is made of stent, plastic beads, filament, beaker etc., it is possible to achieve
Test to foaming properties in foam concrete, and the intensity of different foam can be compared by the formula of 1-1, cost
It is low, workable, for foam concrete foam select it is significant
The content of the invention
Technical problem：The technical problem to be solved in the present invention is to provide a kind of strength test side of foam in foam concrete
The blank of foam concrete field foamy body test method has been filled up in method, the invention, is selected for the foam of foam concrete
It is significant.
Technical solution：To achieve the above object, in foam concrete of the invention the strength test method of foam use with
Lower technical solution is realized, is included the following steps：
1) bead is connected on the stent of top with filament, wherein bead is close to the outer of corresponding beaker；
2) different foams to be measured is prepared at the same time using foaming machine,
3) foam to be measured is fitted into beaker until filling, the height of beaker is h centimetres；
4) filament to be cut, allows bead to fall along beaker inner wall, record bead falls to time t second of beaker bottom of a cup,
5) repeat step 1)-step 4) repeatedly, take multiple time average,
The intensity k=t/h of foam is calculated using equation below
Wherein k is the parameter of characterization foamy body, and t, which is bead, drops to time needed for beaker bottom second, h from being discharged into
For the height centimetre of foam in beaker, wherein the numerical value of k is bigger represents that foamy body is higher.
The mass density of bead described in step 1) should meet relational expression：Mass density >=bead of 70 × foam to be measured
The mass density of mass density >=30 × foam to be measured, guarantee bead can sink in foam concrete foam and fall rate
Will not be too fast.
Bead described in step 1) is dismountable hollow beads, is easily installed filament.
The lower end of bead described in step 1) is less than close to the upper surface of the foam in beaker apart from the upper surface of foam
2mm, to reduce bead and speed during foam contacting to the greatest extent.
Different foams to be measured is prepared at the same time using foaming machine described in step 2), 15 DEG C -30 DEG C of its environment temperature.
It is rapid 3) described in beaker outer wall should mark altitude scale line, easy to measure the sinking distance of bead.
It is rapid 5) described in repeatedly be 3-5 times.
Beneficial effect：The present invention has filled up the blank of foamy body test method in foam concrete, and device is simple, cost
It is relatively low, it is workable, and the intensity of different foam can be quantified by formula, characterization, foam for foam quality select,
The preparation of foam concrete is significant.
Brief description of the drawings
Fig. 1 is the device of the invention schematic diagram.
Have in Fig. 1：Beaker A, filament B, bead C, stent D.
