摘要 本文探讨了橡胶粉对混凝土抗折、抗压强度及抗冲击性能的影响。研究结果表明橡胶粉改性混凝土的抗折、抗压强度较基准混凝土变化不大,冲击荷载则明显提高。采用适当粘结剂可以改善橡胶树与混凝土的界面状况,大幅度提高混凝土的抗冲击性能。 In this paper, the influence of rubber powder on flexural, compressive and impact strength of concretehas been studied. The results show that, in comparison with the contro, there is lttle diifference to nexural and compressive strength of the medifiied concrete. However, the impact property was improved obviosly. Further more byusing suitable adhesion agent, the interface state between rubber and conorete oan be improved, which greatly benefitsthe impact property of concrete.
