Multifunctional UHPC and preparation method thereof
The invention discloses a multifunctional UHPC (Ultra High Performance Concrete) and a preparation method thereof. The multifunctional UHPC comprises 100 parts of cement, 8-25 parts of silica fume, 0-15 parts of fly ash, 80-120 parts of sand, 5-30 parts of quartz powder, 2-6 parts of fibers, 1-8 parts of a high-performance water reducing agent, 7-12 parts of an expanding agent, 0-1.5 parts of SAP super absorbent resin, 0-10 parts of an automobile exhaust absorbing material and 0-24 parts of an internally doped snow melting agent; and the water-binder ratio is 0.15-0.23. The UHPC material prepared by the invention has the advantages of self-compaction, no steam curing, ultrahigh strength, ultrahigh toughness, strong frost resistance, lower 28-day self-shrinkage rate and excellent cracking resistance, and can absorb automobile exhaust from cities or vital communication lines. The method can be widely applied to cement bridge deck defect repair, bridge deck expansion joint treatment, cement bridge deck waterproofing, cement bridge pier repair, steel bridge deck durability pavement and other projects.
本发明公开了一种多功能型UHPC及制备方法。该多功能型UHPC包括：水泥100份、硅灰8～25份、粉煤灰0‑15份、砂80‑120份、石英粉5‑30份、纤维2‑6份、高性能减水剂1‑8份、膨胀剂7‑12份、SAP高吸水树脂0‑1.5份、汽车尾气吸收材料0‑10份、内掺式融雪剂0‑24份，水胶比0.15‑0.23。本发明制备UHPC材料具有自密实、免蒸养、超高强度、超高韧性、抗冻性能强、28天自缩率较低、抗开裂性能优异、可吸收城市或者交通要道上的汽车尾气。可广泛用于水泥桥面缺陷修补、桥面伸缩缝处理、水泥桥面防水、修复水泥桥墩、钢桥面耐久性铺装等项目中。
