Gold tailing sand doped grouting material for semi-flexible pavement and preparation method of grouting material
The invention provides a grouting material doped with gold tailing sand for a semi-flexible pavement and a preparation method of the grouting material. The grouting material is prepared from cement, gold tailings, water, Na2SiO3 powder, NaOH industrial caustic soda flakes and a water reducing agent. The cement concrete comprises the following components in parts by mass: 25-35 parts of gold tailings and 100 parts of cement, the dosage of the water reducing agent is 1/10-1/5 of that of a common cement concrete water reducing agent, the dosage of the Na2SiO3 powder is 3-9% of that of the gold tailings, the dosage of the NaOH industrial caustic soda flakes is 1-4% of that of the gold tailings, and the water-solid ratio is 0.5-0.8. According to the technical scheme, a new mass utilization way of the gold tailings is opened up, and the gold tailings and the cement are reasonably proportioned to replace a large amount of fine sand and a small amount of cement, so that the gold tailings account for more than 35% of the grouting material, the fluidity of construction is met, the normal work of construction is guaranteed, the preparation cost is greatly saved, and the grouting material is suitable for large-scale popularization and application. And on the premise of conforming to corresponding test specifications, the breaking strength of the grouting material is enhanced.
本发明提供了一种掺加黄金尾矿砂的半柔性路面用灌浆料及制备方法，包括：水泥、黄金尾矿、水、Na2SiO3粉末、NaOH工业片碱、减水剂；各组成成份按质量比例为：黄金尾矿25～35份，水泥100份，减水剂用量为普通水泥混凝土减水剂用量的1/10～1/5，Na2SiO3粉末用量是黄金尾矿的3％～9％，NaOH工业片碱用量是黄金尾矿的1％～4％，水固比为0.5～0.8。该技术方案，开辟了一条黄金尾矿新的大宗利用途径，并且通过黄金尾矿与水泥的合理配比，大宗替代了细砂，少量替代了水泥，使得黄金尾矿占灌浆料本身的35％之多，既符合了施工的流动度，保障了施工的正常工作，而且大大节省了制备成本，而且在符合相应试验规范的前提下，增强了灌浆料的抗折强度。
