Vibration-damping anti-freezing fiber-reinforced mineral-based gelling reinforced roadbed filler and preparation method thereof
The invention discloses a vibration-damping anti-freezing fiber-reinforced mineral-based gelatinization-reinforced roadbed filler and a preparation method thereof. The vibration-damping anti-freezingfiber-reinforced mineral-based gelatinization-reinforced roadbed filler is prepared from the following raw materials in parts by weight: 85 to 105 parts of a roadbed filler; 1 to 4 parts of a mineral-based cementing material, 9 to 15 parts of an auxiliary material and 0.5 to 8 parts of anti-crack fiber; the mineral-based cementing material is prepared from the following raw material in parts by weight: 5 to 10 parts of hornblende, 7 to 15 parts of potassium feldspar, 9 to 14 parts of ilmenite, 4 to 8 parts of corundum, 12 to 20 parts of kaolinite, 10 to 18 parts of biotite and 14 to 20 parts of pyroxene; the auxiliary material is prepared from the following raw material in parts by weight: 85 to 95 parts of an alkaline exciting agent, 0.45 to 0.8 part of a surfactant and 2 to 8 parts of awater reducing agent. The problems of roadbed vibration sinking, freezing damage caused by freezing and thawing and the like under the dynamic load effect of a train can be solved. And excellent gel solidification reinforcement and freezing damage prevention and control effects are achieved.
本发明公开一种减振防冻纤维增强矿物基类胶凝强化路基填料及制备方法，按重量份计由如下原料组成：路基填料85‑105份，矿物基类胶凝材料1‑4份，辅料9‑15份和抗裂纤维0.5‑8份，所述矿物基类胶凝材料按重量份计由如下原料组成：角闪石5‑10份、钾长石7‑15份、钛铁矿9‑14份、刚玉石4‑8份、高岭石12‑20份、黑云母10‑18份和辉石14‑20份；所述辅料按重量份计由如下原料组成，碱性激发剂85～95份，表面活性剂0.45～0.8份，减水剂2‑8份。本发明可解决列车动荷载作用下路基振陷、冻融引发冻害等问题。具有极佳的胶凝固化加固与冻害防控效果。
