Method for preparing high-strength ceramsite from engineering spoil
The invention provides a method for preparing high-strength ceramsite by utilizing engineering spoil. The method comprises the following steps: a, crushing and ball-milling the engineering spoil into powder; b, mixing the engineering spoil powder, an auxiliary agent and water to prepare a spherical ceramsite green body; c, naturally airing the ceramsite green body for 60 to 120 minutes; and d, presintering the ceramsite at 400-500 DEG C for 10-30 minutes, roasting at 1100-1200 DEG C for 10-30 minutes, and cooling to room temperature, thereby obtaining the ceramsite. According to the invention, efficient utilization of engineering spoil is realized, occupation of spoil to storage land is reduced, pollution of engineering spoil to air and environment is avoided, exploitation of gravel resources is reduced, and the technical problems of high additive proportion, low spoil utilization rate, low compressive strength of single ceramsite and high water absorption in the prior art are solved.
本发明提供一种利用工程弃土制备高强陶粒的方法，包括以下步骤：a、将工程弃土破碎球磨为粉状；b、将工程弃土粉、助剂、水混合制，球形陶粒坯体；c、将陶粒坯体自然晾制60‑120min；d、将陶粒在400‑500℃预烧10‑30min后，在1100‑1200℃焙烧10‑30min后冷却至室温，制成陶粒。本发明解决工程弃土的高效利用、减少了弃土对存放土地的侵占、避免工程弃土对空气和环境的污染问题，同时减少砂石资源的开采，并解决现有技术中添加剂比例高、弃土利用率低、陶粒单颗粒抗压强度低、吸水率高的技术问题。
