Mortar for rapid repair of airfield pavement and preparation method thereof
The invention discloses mortar for rapidly repairing an airport pavement and a preparation method of the mortar. The mortar is prepared from the following raw materials in parts by weight: 1000-1500 parts of dead burned magnesium oxide powder; 300 to 400 parts of monoammonium phosphate; 200 parts of fly ash; the content of metakaolin is 200 parts; the content of the quartz sand is 1000 to 1500 parts; 100 to 150 parts of a retarder; the invention has the following beneficial effects: after mortar is mixed, the mortar has high fluidity, can be flattened more quickly and more easily, and can be fully attached to the surface of a base material, so that the cohesiveness between the mortar and the base material is improved, and the forming effect of the mortar is improved; along with the increase of mortar curing time, the compressive strength and the breaking strength of the mortar are both increased; the mortar provided by the invention can be cured in a shorter time, has stronger adaptability, and can reach the navigation standard of airport pavements within 1-3 hours at the soonest.
本发明公开了一种用于机场道面快速修复砂浆及其制备方法，包括以下重量份的原料制成：重烧氧化镁粉末为1000‑1500份；磷酸一铵为300‑400份；粉煤灰为200份；偏高岭土为200份；石英砂为1000‑1500份；缓凝剂为100‑150份；水为300份，其有益效果在于：在砂浆混合后，具有较高的流动性，能够更快更容易铺平砂浆，砂浆能够充分贴合基材表面，提高砂浆与基材之间的粘结性，提高砂浆的成型效果；随着砂浆固化时间的增长，其抗压强度和抗折强度都在增大；本发明中的砂浆能够在较快的时间中完成砂浆的固化，适应性更强，最快能在1‑3个小时达到机场道面的通航标准。
