Description

Technical Field

[0001] The utility model relates to the technical field of aggregate testing, in particular to a full-automatic aggregate firmness testing device. Background Art

[0002] Aggregate robustness refers to the ability of aggregate particles to resist disintegration and destruction under various physical erosion effects (such as drying, freezing and thawing, temperature changes, etc.), also known as aggregate durability or volume stability. Aggregate robustness is determined by the sodium sulfate method, which uses the stress formed by the crystallization and expansion of sodium sulfate in the cracks inside the rock to indirectly identify its crack resistance. Aggregates are soaked and dried in a saturated sodium sulfate solution for a total of 5 cycles, and the percentage of mass loss is calculated as the aggregate robustness index.

[0003] The existing aggregate strength test device has some defects:

[0004] 1. The existing test equipment for testing the solidity of concrete aggregates cannot place multiple sieves of different structures for testing at one time, and cannot perform multiple groups of tests at the same time, which wastes time and has low test efficiency;

[0005] 2. The existing test equipment is basically connected to the test basket by chain hoisting. This hoisting method has poor stability and the basket is prone to tilt, causing the aggregate in the basket to spill, resulting in test errors;

[0006] 3. The existing test equipment is not accurate enough in controlling the temperature of the sodium sulfate solution, and cannot monitor the density of the sodium sulfate solution during the process. The authenticity of the test data may be affected due to the decrease in the density and concentration of the sodium sulfate solution;

[0007] 4. The conversion between immersion and drying during the test is completely done manually, the time control is not accurate, and the work efficiency is low;

[0008] 5. After the soaking and drying cycle, the sodium sulfate solution and crystals adhering to the basket and aggregate need to be cleaned manually. Long-term such work is likely to cause corrosion, erosion and other injuries to the test personnel. Utility Model Content
