Yellow River sediment aggregate with alkali-activated material as cementing agent and preparation method thereof
The invention provides Yellow River sediment aggregate with an alkali-activated material as a cementing agent and a preparation method thereof and belongs to the technical field of building materials. According to the invention, a cement-based material with high carbon emission is abandoned, and a green and environment-friendly alkali-activated cementing material is used as a cementing agent of the Yellow River sediment aggregate; wherein, the natural resource of the Yellow River silt is fully utilized, the Yellow River silt and a proper amount of alkali-activated cementing agent are mixed by adopting a rolling granulation principle, and particles with certain strength are formed and used as aggregate to be applied to concrete. Therefore, the problem of aggregate shortage in the plain area of the middle and lower river basins of the Yellow River is solved, a new thought is provided for large-scale resource utilization of the Yellow River sediment, and a solution is provided for solving the problem of sediment deposition of the Yellow River.
本发明提供了一种以碱激发材料为胶结剂的黄河泥沙骨料及其制备方法，属于建筑材料技术领域。本发明摒弃了高碳排放的水泥基材料，使用绿色环保的碱激发胶凝材料作为黄河泥沙骨料的胶结剂；充分利用黄河泥沙这种自然资源，采用滚动造粒原理，将黄河泥沙与适量的碱激发胶结剂混合，形成具有一定强度的颗粒，作为骨料应用于混凝土中。本发明不仅解决了黄河中下游流域平原地区骨料短缺的问题，且为黄河泥沙的大规模资源化利用提供新的思路，也对解决黄河泥沙淤积的问题提出解决方案。
