Ferronickel slag roller compacted concrete and preparation method thereof
The invention relates to the field of recycled building materials, in particular to ferronickel slag roller compacted concrete. The ferronickel slag roller compacted concrete is characterized by comprising the following components in parts by mass: 10-15 parts of Portland cement, 10-15 parts of ferronickel slag powder, 10-15 parts of ferronickel slag particles with the particle size of 1-5 mm, 55-70 parts of ferronickel slag particles with the particle size of 5-25 mm, and water with the amount 0.2-0.3 time that of the cement and the ferronickel slag powder. The invention provides a method forpreparing the roller compacted concrete by using the ferronickel slag powder as a cementing material and the ferronickel slag particles as an aggregate. According to the invention, the ground ferronickel slag powder and cement are creatively compounded to be used as a cementing material, and the sorted ferronickel slag particles are used as the aggregate to be rolled and molded to prepare the road concrete. The method belongs to reutilization of solid waste, turns waste into wealth, and develops a new technology and a new way for additional value utilization of the ferronickel slag.
本发明涉及循环利用的建筑材料领域，具体是一种镍铁渣碾压混凝土；其特征是，包括10‑15质量份的硅酸盐水泥、10‑15质量份的镍铁渣粉、10‑15质量份的1‑5mm的镍铁渣颗粒55‑70质量份的5‑25mm镍铁渣颗粒，水泥和镍铁渣粉用量0.2‑0.3倍的水。本发明提出一种利用镍铁渣粉作为胶凝材，镍铁渣颗粒作为骨料制备碾压混凝土的方法。创新性地提出了利用磨细后的镍铁渣粉与水泥复配作为胶凝材料，利用分选后的镍铁渣颗粒作为骨料经过碾压成型制备道路混凝土。属于固体废弃物的再利用，变废为宝，开发出镍铁渣的附加值利用新技术、新途径。
