Method, i.e., by measurement form cementitious material slurry each material real density, the item in conjunction with known to accounting situation of each material etc.
Part directly calculates mixture slurry density.Due to needing to obtain the real density of all kinds of materials in advance, in addition to practical operation take it is numerous
It is trivial outer, the difficulty of mix-design is on the one hand increased, the promptness and compliance of mix-design are on the one hand also reduced.Separately
A kind of method is the method with reference to the test of mortar apparent density, that is, the slurry quality in fixed volume container is tested, further according to public affairs
Formula, which calculates, obtains slurry apparent density.But it is on the one hand influenced by slurry consistency, the gas swept along in charging process is difficult to by striking
Discharge is hit, on the other hand since container opening area is big, slurry sample demand is big, and it is certain difficult to exist on specific test operation
Degree, and the Numerical accuracy of this method test is not good enough.
Therefore, a kind of device that can simply, effectively and quickly test cementitious material slurry apparent density is developed, is reduced numerous
Trivial test process, it is of far-reaching significance.
In conclusion problem of the existing technology is：
The gas swept along in charging process is difficult to be discharged by tapping, and there are certain difficulty, tests on specific test operation
Numerical accuracy it is not good enough.
Solve the difficulty and meaning of above-mentioned technical problem：
Difficulty is to be influenced by slurry consistency, and on the other hand since container opening area is big, slurry sample demand is big；Meaning
Justice is quickly and effectively to be detected the apparent density of cementitious material, reduces cumbersome test process.

Further, it is carved on the outside of the measurement bottle and is equipped with scale.
Further, the outside diameter of the ground bottle stopper is identical as the inside diameter of bottle is measured, port grinding bottle feeler gauge lattice and survey
Measuring bottle ground matches so that ground bottle stopper can be filled in the opening for measuring bottle, and can good seal.
Another object of the present invention is to provide a kind of glue of the cementitious material slurry apparent density device for quick testing
Gel material slurry apparent density method for rapidly testing, the cementitious material slurry apparent density method for rapidly testing include：By coal
In the dry measurement bottle of oil injection, ground bottle stopper is filled in and is measured in bottle, in identical left at ambient temperature 5 minutes, record
Liquid level h0, ground bottle stopper is extracted, and weigh kerosene and measure the quality of bottle；It needs to detect apparent density with sampler extraction
Cementitious material slurry, injection measure bottle kerosene in, be stoppered ground bottle stopper, jiggle measure bottle make by surface tension and pressure
Difference influences to wrap up in the bubble for investing slurry surface discharge, in identical left at ambient temperature 5 minutes, record liquid level h1, and
Weigh cementitious material slurry, kerosene and the gross mass for measuring bottle.
Further, the computational methods of the cementitious material slurry apparent density：
Wherein：M0For the gross mass of kerosene and measurement bottle, M1For kerosene, cementitious material slurry sample and the total matter for measuring bottle
Amount, h0To measure kerosene liquid level in bottle, h when unimplanted cementitious material slurry1To be measured in bottle after injection cementitious material slurry
Kerosene liquid level, D are the bottleneck inner diameter for measuring bottle.
In conclusion advantages of the present invention and good effect are：
Multiple anti-sway rubber rings are provided with, can be swung to avoid slurry cylinder is moved when being matched with measurement bottle；This hair
It is bright simple in structure, it is at low cost, it can be effectively used for testing the apparent density of variety classes cementitious material slurry, test process letter
It is single, convenient and efficient.
By cement or cement+admixture, mixing is slurried under different water-binder ratios, presses fixed volume container test method respectively
(method 1) and test method of the present invention (method 2), which are divided 3 times, tests same slurry apparent density, and data see the table below.Wherein, cement
Density is 3.130 × 103kg/m3, miberal powder density is 2.870 × 103kg/m3, silicon ash density is 2.210 × 103kg/m3, watertight
Degree is 0.998 × 103kg/m3, additive density is 1.092 × 103kg/m3。
As can be seen from the above experimental data, method 2 has been evaded slurry in test operating procedure and has been swept along compared to method 1
Error caused by introducing additional air and cannot being thoroughly discharged, the fluctuation between 3 test values is small, and test result is more stable,
Closer to calculated value, it can more reflect the truth of apparent density after cementitious material is prepared into slurry.
