Steel slag aggregate and concrete
The invention provides a steel slag aggregate, which is prepared by the following steps: collecting waste plastics taking polyethylene and/or polypropylene as main components, and crushing; mixing the heated asphalt with polyethylene powder and polypropylene powder, keeping the temperature at 175-190 DEG C, and then performing first stirring and shearing to obtain a treating agent; detecting the Brookfield viscosity of the treating agent, maintaining the Brookfield viscosity to be less than or equal to 0.2 Pa.s, and if the Brookfield viscosity is greater than 0.2 Pa.s, controlling the Brookfield viscosity to be less than or equal to 0.2 Pa.s by adjusting the temperature of the treating agent; adding porous steel slag into the treatment agent, and carrying out second stirring; and pouring out the steel slag of which the surface is coated with the treatment agent, and cooling to room temperature to obtain the steel slag aggregate. According to the treatment agent, a mixture of waste plastics and asphalt is used, after the porous steel slag is strengthened, the asphalt wrapping the surface of the porous steel slag has excellent high-temperature deformation resistance and low-temperature crack resistance, and the pavement performance can be improved after concrete is added; the treating agent is wide in source and low in price, and has good affinity with asphalt.
本发明提供一种钢渣集料，由以下方法制备，收集以聚乙烯和/或聚丙烯为主要成分的废塑料，粉碎；将加热的沥青与聚乙烯粉末、聚丙烯粉末混合，保持温度为175‑190℃，然后进行第一搅拌，剪切，得到处理剂；检测所述处理剂的布氏黏度，使其维持在小于等于0.2Pa.s，若大于0.2Pa.s，则通过调整所述处理剂的温度来控制其布氏黏度小于等于0.2Pa.s；将多孔钢渣加入至所述处理剂中，进行第二搅拌；将表面裹覆有处理剂的钢渣倒出，冷却至室温，得到钢渣集料。该处理剂使用了废塑料与沥青的混合物，当完成多孔钢渣的强化后，裹覆于多孔钢渣表面的沥青具有优良的耐高温变形与低温抗裂性能，在加入混凝土后可提高路用性能；且此处理剂来源广泛，价格便宜，与沥青具有良好的亲和力。
