Concrete for shielding radiation
The invention provides concrete for shielding radiation. The concrete is prepared from coarse aggregate, fine aggregate, a cementing material, coal ash, superfine slag powder, an expanding agent, polypropylene fibers, a water reducing agent, self-healing microcapsules and water, wherein the coarse aggregate comprises barite and sandstone, the fine aggregate comprises barite and sandstone, the cementing material comprises Portland cement, the self-healing microcapsule comprises a capsule shell and a glue solution poured into the capsule shell, and the glue solution is a lithium silicate solution or a mixed solution of lithium silicate and sodium silicate. The invention solves the problems of low volume weight and difficulty in shielding linear accelerator radiation of the conventional concrete.
本发明提供了一种用于屏蔽辐射用的混凝土，包括：粗骨料、细骨料、胶凝材料、粉煤灰、矿渣微粉、膨胀剂、聚丙烯纤维、减水剂、自愈微胶囊和水，所述粗骨料包括重晶石和砂石，所述细骨料包括重晶石和砂石，所述胶凝材料包括硅酸盐水泥，所述自愈微胶囊包括囊壳和灌注于所述囊壳中的胶液，所述胶液为硅酸锂溶液、或硅酸锂和硅酸钠的混合液。本发明解决了常规混凝土的容重低且难以满足屏蔽直线加速器辐射的问题。
