Aggregate with irradiation-resistant function, preparation method of aggregate, irradiation-resistant concrete and preparation method of irradiation-resistant concrete
The invention provides an aggregate with an irradiation-resistant function, a preparation method of the aggregate, irradiation-resistant concrete and a preparation method of the irradiation-resistantconcrete. The aggregate comprises boron industrial waste residue recycled aggregate and a cement-based shell coating the surface of the boron industrial waste residue recycled aggregate; the boron industrial waste residue recycled aggregate is prepared from the following raw materials in percentage by weight: 41 to 48 percent of boron mud, 15 to 20 percent of cement, 18 to 25 percent of a mineraladmixture, 5 to 7 percent of sodium silicate, 3.9 to 5.2 percent of an expanding agent, 8 to 15 percent of water and 2.0 to 3.5 percent of a water reducing agent; the cement-based shell layer is prepared from the following raw materials in percentage by weight: 46 to 50 percent of cement, 10 to 13 percent of coal ash, 4.2 to 5.1 percent of silica fume, 25.6 to 30.7 percent of water, 1.0 to 1.6 percent of a water reducing agent and 3.9 to 5.2 percent of an expanding agent. The boron industrial waste residue recycled aggregate is subjected to surface modification by adopting a cement-based material, so that the surface structure and performance of the aggregate can be optimized, the porosity and water absorption rate are reduced, the compactness is improved, and the mechanical property, durability and radiation resistance of the aggregate are further enhanced.
本发明提供一种具有耐辐照功能的集料及其制备方法、耐辐照混凝土及其制备方法。所述集料包括硼工业废渣再生集料和包覆在其表面的水泥基壳层；所述硼工业废渣再生集料包括如下重量百分数的原料：硼泥41‑48％，水泥15‑20％、矿物掺合料18‑25％、硅酸钠5‑7％、膨胀剂3.9‑5.2％、水8‑15％和减水剂2.0‑3.5％；所述水泥基壳层包括如下重量百分数的原料：水泥46‑50％、粉煤灰10‑13％、硅灰4.2‑5.1％、水25.6‑30.7％、减水剂1.0‑1.6％和膨胀剂3.9‑5.2％。采用水泥基材料对硼工业废渣再生集料进行表面改性，能够优化集料的表面结构与性能，降低孔隙率和吸水率，提高密实度，进一步增强其力学性能、耐久性和耐辐照能力。
