摘要：Two groups of variables, the amount of rubber particles and the size of rubber particles, were set up to evaluate the early crack resistance of rubber concrete after 24 hours of forming. Combined with the test results, the influence of the amount and particle size of rubber particles on the early crack resistance of concrete is analyzed. The experimental results show that the early crack resistance of concrete increases with the decrease of the size of rubber particles when the content of rubber particles is small, but decreases first and then increases when the content of rubber particles is large. When the size of rubber particles is large, the early crack resistance of concrete increases with the increase of the content of rubber particles, on the contrary, decreases first and then increases.
