Embodiment Construction
[0055] The present invention will be further described below in conjunction with accompanying drawing.
[0056] Such as figure 1 As shown, the present invention provides a testing device for testing the pumpability of freshly mixed cement-based materials, which includes a pipe body 1 , a carrying device 2 and a force measuring device 3 .
[0057] Wherein, the pipe body 1 is used to provide passages for the circulation of the test medium, and the test medium is freshly mixed cement-based materials such as concrete and mortar. Since the test medium will be subjected to a certain pressure during the pumping process, in order to simulate the real situation of the test medium during the pumping process, the pipe body 1 should be able to withstand the corresponding pressure.
[0058] The carrying device 2 is arranged inside the pipe body 1 for carrying the test medium and making the test medium have a predetermined pressure; the force measuring device 3 is connected with the carryi...

The invention relates to a fresh mixed cement-based material pumping performance testing device and a testing method thereof, which relate to the technical filed of building construction equipment. The testing device and the testing method can solve the technical field of difficult pumping resistance measurement of a traditional pumping test medium. The fresh mixed cement-based material pumping performance testing device comprises a pipe body, a bearing apparatus and a force measurement device. The pressure is loaded on the testing medium in the pipe body by the bearing apparatus to simulate acompressed flow state of the testing medium during a practical pumping process, and the friction resistance between the pipe body and the testing medium under pressure effect can be obtained throughthe force measurement device, and a friction coefficient is calculated. Compared with a traditional measurement method, the friction resistance of the tested medium of the tested medium can be obtained through direct measurement, which is very convenient, because the friction resistance can be obtained by simulating the practical pumping condition, so that the reality and accuracy of the measuredresults can be guaranteed.
Description
technical field [0001] The invention relates to the technical field of building construction equipment, in particular to a device for testing the pumping performance of fresh cement-based materials and a testing method thereof. Background technique [0002] Fresh cement-based materials such as concrete, mortar, etc. Among them, concrete pumping technology is the most commonly used method in building construction, especially in the construction of high-rise and super high-rise buildings. It has irreplaceable advantages. In our country, the current annual production share of pumped concrete has accounted for more than 80% of the total production of commercial ready-mixed concrete. Compared with ordinary concrete, pumped concrete not only needs to meet the ideal indicators such as strength and durability required by the standard, but also needs to meet the requirements of pipeline transportation for concrete, that is, the pumpability index. [0003] When pumping, the concrete ...
