The invention discloses pavement mineral powder prepared by recycling papermaking waste green mud and a preparation method. The pavement mineral powder comprises the following components in percentage by weight: 55-60% of refined green mud, 10-15% of fly ash, 5-7% of slag, 10-15% of waste ore powder, 3-6% of a fiber mixture and 3-6% of a composite dispersing agent. The prepared pavement mineral powder is high in apparent density, low in hydrophilic coefficient, low in water content, extremely high in chemical stability, extremely high in chemical corrosion resistance, good in flame retardant property and high temperature resistance, good in economic benefit, suitable for popularization, capable of achieving repeated utilization of waste green mud, and improving the added value of the green mud.
本发明公开了一种造纸废弃物绿泥回收后制作的路面矿粉及制备方法，路面矿粉包括以下重量百分比的组分：精致绿泥占比为55‑60％、粉煤灰占比为10‑15％、炉渣占比为5‑7％、废矿石粉末占比为10‑15％、纤维混合物3‑6％和复合分散剂3‑6％。本发明制备的路面矿粉视密度高、亲水系数低、长时间放置有团结块且含水量低，且具有极高的化学稳定性、极强的抗化学腐蚀性、良好的阻燃性能及耐高温性能，具有良好的经济效益，适于推广，实现了对废物绿泥的重复利用，提升了绿泥的附加价值。
