[0002] Foamed concrete, also known as air bubble concrete, is a new type of lightweight thermal insulation material containing a large number of closed pores formed by mechanically foaming the foaming agent through the foaming system of a bubble machine, evenly mixing the foam with cement slurry, and then passing through the pumping system of the foaming machine for cast-in-place construction or mold forming, and naturally curing.
[0003] Existing foamed concrete needs to undergo various tests after production. The methods for measuring foamed concrete include the plate method and the water float method. When using the plate method to measure density, there is likely to be concrete residue inside the measuring plate. Too much residue will affect the accuracy of subsequent density detection. In addition, if a tensile test is required after the density test of the foamed concrete, the sample plate needs to be transferred to other equipment, and the steps are relatively cumbersome.
