Concrete road rapid repairing master batch and concrete road repairing material
The invention discloses a concrete road quick repair master batch which comprises the following components in percentage by mass: 10-30% of ordinary Portland cement P.O42.5, 55-75% of quick-hardeninghigh-strength cement, 5-10% of dry powder plasticizer and 3-5% of defoaming agent. The invention also discloses a concrete road repairing material, which comprises the concrete road rapid repairing master batch, gravels and medium-coarse sand. The invention relates to a concrete road repairing material, which is prepared by uniformly mixing and stirring a rapid repairing master batch, gravels andmedium-coarse sand in proportion under factory conditions to form dry-mixed concrete with a specified label, and only adding water and stirring when the concrete road repairing material is used on site. The method is used for repairing engineering of filling pits, grooves and excavation, and repairing pavements. The method has the characteristics of good construction fluidity, quick solidification, high early strength, quickness, simplicity, convenience and the like. Early opening of road maintenance project traffic is facilitated, so that the comprehensive maintenance cost is reduced, and thetraffic pressure is relieved.
本发明公开了一种混凝土道路快速修补母料，按质量百分比计，包括10‑30％的普通硅酸盐水泥P.O42.5、55‑75％的快硬高强水泥、5‑10％的干粉塑化剂、及3‑5％的消泡剂。还公开了一种一种混凝土道路修补料包括上述的混凝土道路快速修补母料，还包括碎石、中粗砂。本发明所涉及的一种混凝土道路修补料，是将快速修补母料，与碎石，中粗砂按比例在工厂条件下混合搅拌均匀成规定标号的干混混凝土，现场使用时只需加水搅拌即可。用于填补坑洼，沟槽和开挖的修补工程，以及路面修补。具有施工流动度好，凝固快，早强高，快速简便等特点。便于道路维修项目交通的及早开放，从而降低综合维护成本，缓解交通压力。
