高延性混凝土技术简介 (High Ductility Concrete Technical Profile)

特点 (Features)

高延性混凝土（HDC）是一种具有超高延展性（变形能力达普通混凝土200倍）和高韧性（抗拉强度为普通混凝土5-200倍）的特种复合材料，其极限延伸率（ε≥5%）和多裂缝开展能力（裂而不坏）显著优于传统混凝土。通过掺入合成纤维（如聚丙烯纤维）和微膨胀剂，实现自愈合能力（高温下纤维溶解形成蒸汽通道）和抗裂性提升（裂缝宽度≤0.1mm），同时具备耐火性（高温下纤维保护基体）和低收缩性（竖向膨胀率0.02%-0.03%）。

优点 (Advantages)

施工高效：单面压抹10-20mm厚度即可完成加固，无需钢筋/模板，节省材料70%、工期70%；
抗震性能卓越：可抵抗9度及以上地震，砌体结构加固后9度罕遇地震下无裂缝；
环保安全：掺粉煤灰减少碳排放，符合GB/T 50448-2008标准，无VOC排放；
多功能性：兼具自愈合、耐油渗（机油浸泡强度提升10%）和耐高温（500℃热震稳定）特性。

用途 (Applications)

建筑抗震加固：砌体墙/空斗墙单面加固（抗剪承载力提升30%-50%），保护历史建筑风貌；
桥梁隧道修复：桥墩/衬砌抗裂增强（承载力恢复率≥95%），适应高湿度/腐蚀环境；
水利工程：水坝/渠道防渗处理（抗氯离子渗透提升5倍），延长设施寿命30年以上；
工业设施：化工厂房耐腐蚀地面、核电站安全壳加固（耐辐射/热震）。

High Ductility Concrete Technical Profile

Features

High Ductility Concrete (HDC) is a composite material with extreme ductility (200× deformation capacity of ordinary concrete) and high toughness (tensile strength 5-200× higher). Key features include self-healing (fiber dissolution creates vapor channels under heat), crack resistance (crack width ≤0.1mm), fire resistance (fiber protection at 500℃), and low shrinkage (0.02%-0.03% vertical expansion). Fiber reinforcement (e.g., polypropylene) and micro-expansive additives enable multi-crack development (energy absorption 5× higher) and alkali resistance (alkali content ≤0.6%).

Advantages

High efficiency: 10-20mm single-layer application without rebar/templates, saving 70% materials and 70% time;
Seismic resilience: Resists 9+ magnitude earthquakes, achieving 0 cracks in 9-degree seismic tests;
Eco-safety: Fly ash integration reduces emissions (GB/T 50448-2008 compliant), zero VOC;
Multi-functionality: Self-healing, oil/water resistance (10% strength gain after immersion), and thermal shock stability.

Applications

Building seismic retrofit: Masonry wall reinforcement (shear capacity +30%-50%), preserving historic structures;
Bridge/tunnel repair: Pier/lining crack resistance (load recovery ≥95%), suitable for humid/corrosive environments;
Water infrastructure: Dam/channel anti-seepage (chloride resistance 5× higher), 30+ year lifespan extension;
Industrial facilities: Chemical plant floors, nuclear reactor containment (radiation/thermal shock resistance).
