Inorganic grouting material for semi-rigid pavement for solving ruts
The invention discloses a semi-rigid pavement inorganic grouting material for solving ruts, which comprises the following components in percentage by mass: 30 to 50 percent of ordinary Portland cement P.O42.5, 13 to 35 percent of quick-hardening high-strength cement, 3 to 8 percent of dry powder plasticizer, 1 to 4 percent of defoaming agent, 18 to 20 percent of inorganic iron oxide black pigment and 8 to 15 percent of superfine quartz sand. The inorganic grouting material disclosed by the invention has the advantages of excellent permeability and flowability, good construction performance, fast strength increase, good durability and the like; meanwhile, the inorganic grouting material is prepared by uniformly mixing and stirring the rapid high-strength cement, the ordinary Portland cement and the iron oxide pigment with poorer dispersity in proportion at a high speed under factory conditions to form a dry blend meeting specified indexes, and only water needs to be added for stirring when the inorganic grouting material is used on site. The mortar has the characteristics of good construction fluidity, good permeability, fast solidification, high early strength, rapidness, simplicity and convenience and the like. And early opening of road maintenance project traffic is facilitated, so that the comprehensive maintenance cost is reduced, and the traffic pressure is relieved.
本发明公开了一种应用于解决车辙的半刚性路面用无机灌浆料，按质量百分比计，包括30％‑50％的普通硅酸盐水泥P.O42.5，13％‑35％的快硬高强水泥，3％‑8％的干粉塑化剂，1％‑4％的消泡剂，18％‑20％的无机氧化铁黑颜料和8％‑15％的特细石英砂；本发明所公开的无机灌浆料具有优异的渗透流动性能，施工性能良好，强度增长快，耐久性好等优点；同时该无机灌浆料，是将快速高强水泥，与普通硅酸盐水泥及分散性较差的氧化铁颜料按比例在工厂条件下高速混合搅拌均匀成符合规定指标的干混料,现场使用时只需加水搅拌即可。具有施工流动度好,渗透性好，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。
