Silty soil/Yellow River sediment unfired lightweight aggregate and preparation method thereof
The invention belongs to the technical field of building artificial aggregates, and provides a silty soil/Yellow River sediment unfired lightweight aggregate and a preparation method thereof. The cold-viscous lightweight aggregate is obtained by mixing, extruding, granulating and curing the following raw materials: Yellow River silt, silty soil and an inorganic cementing material, and the mass ratio of the Yellow River silt to the silty soil is (50-70): (30-50); the mixing amount of the inorganic cementing material is 8-15% of the total mass of the Yellow River silt and the silty soil. The Yellow River silt is taken as a main component, silty soil is doped to improve the grading and compactness of the mixed soil, the inorganic cementing material is used for solidifying the mixed soil to ensure that the mixed soil has enough strength and stability, and the preparation of solidified Yellow River silt particles is realized by regulating and controlling the extrusion granulation process; the invention has the advantages of simple process and low energy consumption, realizes the resource utilization of the Yellow River sediment, can use local materials in the areas lacking stones in the Yellow River area, and greatly reduces the engineering construction cost.
本发明属于建筑人造集料技术领域，提供了一种粉砂土/黄河泥沙免烧轻集料及其制备方法。所述冷粘轻集料是将以下原料混合挤压造粒后养护得到，原料为黄河泥沙、粉砂土和无机胶凝材料，黄河泥沙和粉砂土质量比为50～70：30～50；无机胶凝材料掺量为黄河泥沙和粉砂土总质量的8～15％。本发明以黄河泥沙为主要组分，掺入粉砂土以提高混合土的级配与密实性，以无机胶凝材料进行固化混合土保证其具有足够的强度和稳定性，并通过挤压造粒过程的调控，实现了固化黄河泥沙颗粒的制备，能够用于充当填充路基的人造轻集料，工艺简单，能耗低，实现了黄河泥沙的资源化利用，并能在黄泛区缺乏石料的区域就地取材，极大的减少了工程建设成本。
