Description

Technical Field

[0001] The utility model relates to the technical field of cement-stabilized crushed stone detection, in particular to a cement-stabilized crushed stone anti-segregation measuring device. Background Art

[0002] Cement stabilized crushed stone uses graded crushed stone as aggregate, uses a certain amount of cementitious materials and sufficient mortar volume to fill the gaps in the aggregate, and is spread and compacted according to the interlocking principle. Its compaction is close to density, and its strength mainly depends on the interlocking principle between the crushed stones. At the same time, there is enough mortar volume to fill the gaps in the aggregate. After cement stabilized crushed stone is cured, it will not be muddy when it rains, and its surface is solid. It is an ideal base material for high-grade pavement. During construction, the cement stabilized crushed stone after mixing needs to be tested for anti-segregation before subsequent construction work can be carried out.

[0003] Traditional testing work generally involves the cement-stabilized gravel in a conical bucket falling into a sieve, and the fluidity of the cement-stabilized gravel being tested by calculating the time it takes for the concrete on the sieve to flow onto the testing platform. The staff also needs to observe the flow state of the cement-stabilized gravel on the testing platform. Since the staff are performing timing and observation work at the same time, it is easy for the staff to make mistakes in calculating the anti-segregation rate of the cement-stabilized gravel, resulting in a decrease in the quality of the cement-stabilized gravel anti-segregation measurement work. At the same time, after the test, the staff is required to clean up the crushed materials on the testing platform, which increases the staff's work intensity. Therefore, we need to propose a cement-stabilized gravel anti-segregation measurement device. Utility Model Content
