Cement paste fluidity tester with timing function

Abstract

The invention discloses a cement paste fluidity tester with a timing function, and the tester comprises a glass plate, wherein the plane shape of the glass plate is square, the bottoms of four corners of the glass plate are respectively provided with an adjustable footstand for adjusting the levelness of the glass plate, and an embedded level bubble is arranged in the center of the glass plate; a dial with a circular plane shape is arranged on the glass plate, the dial and the glass plate are concentric, the dial is printed on the upper surface of the glass plate, a scale circle which is the same as the lower port of the conical mold cylinder is printed in the center of the dial, and the scale circle covers the level bubble; at least four scale marks which are perpendicular to one another are arranged on the dial along the scribed circle to the outer circle where the dial is located; and a timer is also arranged on the glass plate. Compared with the conventional instrument for detecting the fluidity of the cement paste, the device disclosed by the invention has the advantages that other tools are not required to be prepared, rapid leveling can be realized, the timer has a reminding function, so that the measurement time is accurate, the conventional overtime phenomenon is avoided, and the measurement data is more intuitive, more convenient and more accurate to read.

Description

technical field [0001] The invention relates to a device for measuring the fluidity of cement paste in the homogeneity index of admixtures in the field of building materials, in particular to a cement paste fluidity measuring instrument with a timer. Background technique [0002] The test process of the fluidity of the cement slurry is to quickly inject the mixed slurry into the truncated cone mold and lift the truncated cone mold in the vertical direction, and at the same time start the stopwatch for timing, and let the cement slurry flow on the glass plate (the glass plate should be adjusted to the horizontal State) flow up to 30s, use a ruler to measure the maximum diameter of the flowing part in two directions perpendicular to each other, and take the average value as the fluidity of cement paste. [0003] In the prior art, the utility model patent of Chinese Patent Publication Publication No. CN202562827U discloses a clean pulp fluidity measuring device, which includes ...

AI Technical Summary

Problems solved by technology

[0005] However, due to the need to be equipped with additional timers such as a stopwatch during the test, and it is necessary to pay attention to the timing of the stopwatch and read the value on the other side during the operation, dual-use is likely to cause test errors

Therefore, the prior art has not yet considered the problem of how to make it easy to read the measured value during accurate timing and operation during this type of test.
