【Abstract】 The study investigates the influence of different rubber particles quality, modification method, amount of rubber particles,and particle size on the abrasion-resistant performance of rubber concrete and explains the anti-abrasion and anti-erosion mechanism of the“Tough Base Anchoring Airbag”. The research results indicate that: the incorporation of rubber particles could enhance the toughness of concrete; high-quality outer tire rubber particles can only exhibit their superior properties after modification; the amount and the size of rubber particles are positively correlated with the anti-abrasion and anti-erosion strength of rubber concrete; the NaOH + KH570 composite modification method can significantly improve the compressive strength and abrasion-resistant strength of rubber concrete; the rubber concrete introduced in this paper offers a higher cost-performance ratio.更多还原
