Description

Coarse aggregate abrasion test device Technical Field The utility model relates to the technical field of coarse aggregate detection, in particular to a coarse aggregate abrasion test device. Background Coarse aggregate is usually stone or mineral particles with the particle size of more than 5mm, is a main raw material in building materials such as concrete, mortar, asphalt mixture and the like, the quality of the coarse aggregate directly influences the strength, durability and stability of the engineering, so that the coarse aggregate is very important to select, process and detect, the coarse aggregate abrasion test is a test for evaluating the abrasion resistance of the coarse aggregate under traffic load and other external conditions, the main purpose of the coarse aggregate abrasion test is to measure the abrasion degree of the coarse aggregate under the action of friction and impact so as to ensure that excessive abrasion or strength reduction cannot be caused in the long-term use process of the aggregate, the quality and durability of engineering materials such as concrete, asphalt mixture and the like are influenced, the building standards of different countries or regions have different requirements on the abrasion rate of the coarse aggregate, and the aggregate with lower abrasion rate is more suitable for engineering projects with higher requirements. In coarse aggregate abrasion test, coarse aggregate and apron have certain weight, and general test device is when using, is difficult to carry out the loading and unloading of coarse aggregate and the dismouting of apron, and test work needs more manual work and longer time, greatly reduced work efficiency, simultaneously, after the test is accomplished, coarse aggregate is difficult for collecting, and coarse aggregate drops to the device gap easily in, influences the test result, and general device is after the test is accomplished, and the inside dust that drifts more of cylinder, when unloading, the dust is drifted everywhere in the air easily, causes certain injury to staff's health, solves above-mentioned problem, proposes a coarse aggregate abrasion test device now.
