Preparation method of road edge stone
The invention relates to the technical field of road traffic stone processing design, and discloses a road traffic stone preparation method, which comprises: 1, waste tire rubber powder treatment; step 2, preparing a cementing material; 3, modifying the waste aggregate; step 4, adding an admixture; 5, the water-binder ratio is controlled to be 0.25-0.35, and the strength and durability of the concrete are ensured; and step 6, uniformly mixing the materials, putting the mixture into a stirrer, stirring at the speed of 300-500rpm for 2-4 hours, and pouring the mixture into a mold for curing after stirring to obtain the road edge stone. The waste tire rubber powder is treated with silane and siloxane, release of volatile organic compounds and heavy metal is reduced, high-performance ordinary Portland cement or cement doped with nanometer materials is selected, the strength and durability of concrete are improved, the adhesive force and durability of aggregate are improved, and the service life of the concrete is prolonged. The beneficial effect that the durability of the road edge stone prepared from the waste material is close to that of standard aggregate is achieved.
本发明涉及路沿石加工设计技术领域，且公开了一种路沿石的制备方法，所述路沿石制备包括以下步骤：步骤一、废胎胶粉处理；步骤二、胶凝材料；步骤三、废料骨料改性；步骤四、加入掺合料；步骤五、控制水胶比在0.25‑0.35，确保混凝土的强度和耐久性；步骤六、将上述材料均匀混合后投入搅拌机，搅速为300‑500rpm，搅拌时长为2h‑4h，搅拌完毕后倒入模具固化，得到路沿石。本发明通过用硅烷和硅氧烷处理废胎胶粉，减少挥发性有机化合物和重金属的释放，选择高性能普通硅酸盐水泥或掺有纳米材料的水泥，提高混凝土的强度和耐久性，提高骨料的附着力和耐久性，达到了使用废料制备而成的路沿石耐久度性能接近标准骨料的有益效果。
