| 中文摘要: |
| 将废旧轮胎橡胶制备的颗粒橡胶（CR）和粉末橡胶（PR）掺入工程水泥基复合材料（ECC）制备橡胶改性工程水泥基复合材料（RECC），研究CR和PR对RECC性能的影响。结果表明：随着CR或PR含量的增大，RECC的抗压强度减小，但拉伸延性和应变硬化性能提高；随着CR含量的增大，RECC的耐化学介质腐蚀性能先提高后降低，当CR含量增大至15%时，RECC的耐酸和耐硫酸盐腐蚀性能显著提高，当CR含量过大时，RECC的抗压强度损失率增大；在冲击载荷作用下，RECC的稳定性和损伤容限增大，RECC是一种理想的抗冲击结构材料。 |
| 英文摘要: |
| The rubber-modified engineered cementitious composites （RECC）were prepared by incorporating crumb rubber （CR） and powdered rubber （PR） derived from waste tire rubber into the engineered cementitious composites （ECC），and effects of CR and PR on the properties of the RECC were researched.The results showed that，with CR or PR content increasing，the compressive strength of the RECC decreased，while the tensile ductility and strain-hardening performance increased.With CR content increasing，the corrosion resistance of the RECC to chemical media first increased and then decreased.When CR content reached 15%，the corrosion resistance of the RECC to acid and sulfate significantly increased，but when CR content was excessive，the compressive strength loss rate of the RECC increased.Under impact loading，the stability and damage tolerance of the RECC increased，the RECC was an ideal impact-resistant structural material. |
