How to make fill x particles 3.53/18/2024 With the rapid increase in the number of automobiles, how to deal with a large number of waste tires and further meet the needs of energy conservation and environmental protection have become an unavoidable problem waste tires were in urgent need of treatment. The smaller the shear rate is, the more gently the shear strength decreases. The larger the shear rate is, the smaller the shear displacement is and the faster the shear strength decreases. Additionally, the shear rate has a little effect on the peak shear stress. Under the vertical load of 60 kPa, the reinforcement effect of 4% tire volume content is the best, and the peak shear stress increases by 46.53%. However, with the increase of the tire volume content, the reinforcement effect of the tire slices first increases and then decreases, and the effect is best when the tire volume content is 4%. The peak shear stress increases with the increase of vertical load. The test results show that the addition of tire slices can increase the internal friction angle and cohesion of concrete particles, therefore increase the shear strength of crushed concrete particles. In order to study the mechanical properties of tire slices reinforced crushed concrete particles, a series of shear tests were carried out under the conditions of different vertical loads, different tire volume contents, and different shear rates.
