Special high-strength rapid repairing material for airport runway
The invention discloses a special high-strength rapid repairing material for an airfield runway. The special high-strength rapid repairing material comprises the following components in parts by weight: 350-500 parts of sulphoaluminate cement, 400-500 parts of sand, 20-100 parts of silica fume, 2-3 parts of a water reducing agent, 0.1-1 part of a coagulant, 1-5 parts of a retarder and 80-140 parts of water, and the water-binder ratio is 0.20-0.26. The special cement sulphoaluminate cement and the silica fume are combined, it is guaranteed that the later strength does not shrink on the basis that rapid hardening and early strength are met, the obtained high-strength rapid repairing material meets the 15-20-minute construction performance, and meanwhile the high-strength rapid repairing material has the advantages of being high in setting rate and high in early strength; the cement concrete pavement superficial layer repairing material meets the performance index requirements on the cement concrete pavement superficial layer repairing material of the airport road in Technical Guidelines for Maintenance of Civil Airport Airport Aviation District (AC-140-CA-2010-3).
本发明公开了一种机场跑道专用高强快速修补材料，按照重量份数计包括硫铝酸盐水泥350–500份、砂400–500份、硅灰20–100份、减水剂2–3份、促凝剂0.1–1份、缓凝剂1–5份、水80–140份，水胶比为0.20–0.26。本发明选用特种水泥硫铝酸盐水泥和硅灰结合，在满足快硬、早强的基础上保证后期强度不倒缩，得到的高强快速修补材料满足15–20分钟施工性能，同时具有凝结速率快、早期强度高的特点，符合《民用机场飞行区场地维护技术指南》(AC‑140‑CA‑2010‑3)中对机场道路水泥混凝土道面浅层修补材料的性能指标要求。
