Rapid road repairing material and preparation method thereof
The invention discloses a rapid road repairing material and a preparation method thereof. The rapid road repairing material comprises a raw material component A, a raw material component B, a raw material component C and water, the component A comprises magnesium oxide, cement and fine aggregate; the component B comprises phosphate, microbeads, a thickening time control agent and fine aggregate; and the component C is broken stone. The setting time of the system can be adjusted and controlled within 10-40 min through the setting time control agent; by doping cement, superfine powder microbeads and reasonable graded aggregate, the compactness of the system is improved, and the water resistance of the system is improved; by utilizing the acid-base reaction principle of magnesium oxide and phosphate, the early strength and bonding strength of the system are high, the 1h compressive strength is greater than 25MPa, the bonding strength is greater than 3.5 MPa, early traffic opening is facilitated, and the system is particularly suitable for construction under the negative temperature condition.
本发明公开了一种道路快速修补材料及其制备方法，包括原料A组分、B组分、C组分和水；所述A组分包括氧化镁、水泥、细骨料；所述B组分包括磷酸盐、微珠、调凝剂、细骨料；所述C组分为碎石。本发明通过调凝剂，使得体系凝结时间在10‑40min可调可控；通过水泥、超细粉体微珠及合理的级配骨料的掺入，改善体系的密实性，提高体系的耐水性能；利用氧化镁与磷酸盐的酸碱反应原理，使得体系早期强度和粘结强度高，1h抗压强度大于25MPa，粘结强度大于3.5MPa，有助于较早开放交通，特别适合于负温条件下施工。
