Artificial aggregate and preparation method thereof
The invention relates to an artificial aggregate and a preparation method thereof, and belongs to the technical field of preparation of anti-radiation concrete raw materials. The artificial aggregate comprises a metal shell, a porous structure and water-based liquid, and the metal shell is of a sealed structure and used for containing the porous structure; the porous structure is formed by mixing ceramsite raw materials and powdery B4C or Gd2O3 with the weight ratio of 1%-10%, the weight of the B4C accounts for 20%-80% of the total weight of the powdery B4C or Gd2O3, the particle size of the powdery B4C or Gd2O3 is 10 micrometers, the powdery B4C or Gd2O3 is formed into a specified shape, and an obtained formed body is dried and fired. The water-based liquid is natural water, tap water or boric acid solution contained in pores of the porous structure. The artificial aggregate is convenient to obtain, the preparation process is simple, the production process is highly industrialized, novel concrete with the water content, workability, fast neutron moderation capacity and thermal neutron absorption capacity superior to those of existing concrete can be prepared, and the requirements of nuclear radiation in special nuclear facilities, especially neutron shielding structure construction are met.
本发明涉及一种人造骨料及其制备方法，属于防辐射混凝土原材料制备技术领域。该人造骨料包括金属外壳、多孔结构和水基液体，金属外壳为密封结构，用于容纳多孔结构；多孔结构为陶粒原料与1％～10％重量比的粉末状B4C或Gd2O3进行混合，其中，B4C的重量占粉末状总重量的20％～80％，粉末的粒径10微米，成形为规定形状，使得到的成形体干燥后烧制而成；水基液体为容纳于多孔结构孔隙中的天然水、自来水或硼酸溶液。该人造骨料取材方便，其制备流程简单，生产流程高度工业化，可以制备得到含水率、工作性、快中子慢化能力、热中子吸收能力均优于现有混凝土的新型混凝土，满足特殊核设施中的核辐射特别是中子屏蔽结构建设的需求。
