Quick-setting high-strength anti-crack pavement patching material and preparation method and application thereof
The invention relates to a quick-setting high-strength anti-crack pavement patching material and a preparation method and application thereof, belonging to the technical field of cement production. The pavement patching material comprises the following raw materials in percentage by mass: 50 to 60% of micro-expansion moderate-heat Portland cement and sulphoaluminate cement, and 40 to 50% of auxiliary materials, wherein a mass ratio of the micro-expansion moderate-heat Portland cement to the sulphoaluminate cement is 1: (1-3); and the auxiliary materials are composed of the following raw materials in percentage by mass: 0.4 to 0.6% of fibers, 2.5% of rubber powder, 0.2% of a water reducing agent, 0.03% of a defoaming agent, 31 to 34% of fine sand and 8 to 11% of fly ash, and the proportionsof the fibers, the rubber powder, the water reducing agent, the defoaming agent, the fine sand and the fly ash are the percentages of the components based on the mass of the whole repair material. The quick-setting high-strength anti-cracking pavement patching material is prepared from the micro-expansion moderate-heat Portland cement, the sulphoaluminate cement and the auxiliary materials, so pavement patching cost is reduced, quick patching is realized, and obvious economic and social benefits are produced.
本发明涉及一种快凝高强抗裂路面修补料及其制备方法与应用，属于水泥生产技术领域，该路面修补料包括如下质量比的原料：微膨胀中热硅酸盐水泥+硫铝酸盐水泥50‑60％，和辅助料40‑50％，其中，微膨胀中热硅酸盐水泥：硫铝酸盐水泥的质量比为1：(1～3)；所述辅助料包括如下质量比的原料：0.4‑0.6％纤维、2.5％胶粉、0.2％减水剂、0.03％消泡剂、31‑34％细沙、8‑11％粉煤灰，其中，所述纤维、胶粉、减水剂、消泡剂、细沙、粉煤灰的占比是与整个修补料质量的百分比。本发明利用微膨胀中热硅酸盐水泥、硫铝酸盐水泥配以辅助料制备快凝高强抗裂路面修补料，降低道路修补成本，且实现快速修补，经济、社会效益明显。
