Drawings
Fig. 1 is a schematic view of the overall structure of the embodiment of the present invention.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and examples.
As shown in fig. 1, a filling slurry laboratory measuring device comprises a barrel 4 and a base 5 installed at the bottom of the barrel 4, wherein an external thread is arranged on the outer wall of the bottom of the barrel 4, an installation groove matched with the bottom of the barrel 4 is arranged at the top of the base 5, and an internal thread matched with the external thread is arranged on the wall of the installation groove.
Further, the bottom of the mounting groove is provided with a sealing gasket 6.
Scales are arranged on the outer wall of the barrel 4.
Still including installing top cap 3 at barrel 4 top, be equipped with the external screw thread on the top outer wall of barrel 4, set up on the 3 inner walls of top cap with barrel 4 top external screw thread matched with internal thread.
Further, a rubber seal ring 7 is arranged in the top cover 3.
Barrel 4 and top cap 3 and base 5 can be dismantled through the screw thread mode respectively and be connected in this embodiment, convenient to detach and washing, convenient to use.
Further, horizontal detection mechanism is installed at the top of top cap 3, horizontal detection mechanism includes circular universal air level 1, annular magnet 2 is installed at the top of top cap 3, circular iron sheet with annular magnet 2 matched with is installed to 1 bottom surface of circular universal air level. Whether the reference surface with circular universal air level 1 can detect on top cap 3 is in the horizontal plane on arranging top cap 3 in, and then adjustment measuring device's position avoids the uneven reading error that causes of level in the barrel 4.
During measurement, the cylinder 4, the top cover 3 and the base 5 are enclosed to form a closed measuring device with the volume of 500 ml. The cylinder 4 in this embodiment is made of acrylic material.
The steps for measuring the filling slurry shrinkage rate, the bleeding rate and the volume weight in the embodiment are as follows:
(1) during measurement, the cylinder body 4 and the base 5 are connected to form a slurry tank, clear water is filled in the slurry tank, and the top cover 3 is installed at the upper end of the cylinder body 4 to form the measuring device. The measuring device is turned upside down to check for water leakage. After the inspection is finished, pouring out clean water to wipe off the inner wall of the cylinder 4, and weighing the mass M of the measuring device1And standing by.
(2) Preparing the filling slurry according to the required concentration and the sand-lime ratio, filling the slurry tank and covering the top cover 3, and weighing the mass M2Calculating the mass M = M of the filling slurry2-M1And then the total water amount m in the filling slurry is calculated.
(3) Whether the measuring device is adjusted to be on the horizontal plane or not through the round universal level bubble 1 on the top cover 3, the reading error caused by the inclination of the measuring device is avoided, and after the filling slurry is hardened, the volume V of the drained water is read out through the scale marks on the cylinder 4Water (W)And the volume V of the filling slurry after curing.
(4) According to the measured filling slurry mass M, total water quantity M, volume V of solidified filling slurry and volume V of secreted waterWater (W)The shrinkage rate and bleeding rate of the filling slurry (the density of water is 1 g/cm) can be calculated by formula3) And volume weight, the calculation formula is:
shrinkage = (500-V)/500X 100%
Bleeding rate = VWater (W)/m×100%
Volume weight = M/500 × g.
