Technical Field

[0001] The utility model relates to the technical field of mortar performance detection, in particular to a mortar initial drying anti-cracking tester. Background Art

[0002] At present, with the standardization of construction projects, the quality of construction projects has been significantly improved, and all materials in construction projects need to be tested by professional testing agencies. Among them, mortar used in decoration projects is an important item, and an important parameter of mortar testing is the performance of crack resistance after solidification.

[0003] According to the existing patent, the test box supports the fan and the support plate in the required position, which is convenient for performing relevant test operations on the mortar; when the fan is working, the dust net covers the fan, making it difficult for the fan to cause harm to the human body. When the fan needs to be cleaned and maintained, the user operates the connecting mechanism to separate the mounting block from the connecting block, and then removes the dust net from the test box, thereby realizing the convenient disassembly and assembly function of the dust net, which is convenient for performing relevant maintenance operations on the fan.

[0004] The above-mentioned mortar tester cannot adjust the bottom plate during use, so it is impossible to test mortars in different flow states or at different depths. After the test is completed, the mortar has been fixed and formed, resulting in the mortar sticking to the bottom plate of the tester, making demoulding inconvenient. Therefore, we propose a mortar initial drying anti-cracking tester to solve the above problems. Utility Model Content
