中文摘要：
利用工业废渣多元协同激发、有机外加剂与无机辅料复合和纤维增强技术,通过复合工业废渣大掺量取代水泥(20%～50%),使用减水率40%的新型聚缩类高效外加剂、掺入短切钢纤维,使用常规工艺,在自然养护条件下成功制备强度等级大于100 MPa的超高性能防护工程材料。基于经验公式,系统研究基体强度(C100,C150,C200)和钢纤维对混凝土靶体抗侵彻、抗爆炸性能的影响规律。试验结果表明:绿色超高性能混凝土具有优异的抗侵彻、抗爆炸性能。C200单位厚度能耗达到516 kJ/m,相对于C40提高近45%;材料侵彻系数为0.389 mm2.s/kg,仅为C40的75%;爆炸压缩系数为0.051 m/kg1/3,与活性粉末混凝土材料(RPC)相当;具有优异的抗二次爆炸、抗震塌性能。
