Phosphogypsum neutron ray shielding aggregate and preparation method thereof
The invention discloses ardealite neutron ray shielding aggregate which comprises the following components in percentage by weight: 70-90% of ardealite, 2-5% of superfine active admixture, 1-5% of industrial waste residue, 0-30% of functional component, 5-10% of cement, 0.5-5% of alkaline activator and 1-5% of pore-forming agent, the water-binder ratio is 0.16 to 0.45. The phosphogypsum is used as a main raw material, cement, a superfine active admixture, an exciting agent, a pore-forming agent and the like are further combined for a composite excitation hydration reaction, a lightweight aggregate system with rich fine communicating pores is formed, meanwhile, boron and lead components with a shielding effect are subjected to space crosslinking through a cementation reaction, and the shielding effect is achieved. And the shielding capability on neutron rays can be further obviously improved. The ardealite aggregate disclosed by the invention has good mechanical properties, water storage and release properties and neutron ray resistance, and high-value utilization of ardealite can be realized; the preparation method is simple and controllable, low in energy consumption and suitable for popularization and application.
本发明公开了一种磷石膏中子射线屏蔽集料，各组分及其含量包括：磷石膏70～90％，超细活性掺合料2～5％，工业废渣1～5％，功能组分0～30％，水泥5～10％，碱性激发剂0.5～5％，造孔剂1～5％；水胶比0.16～0.45。本发明以磷石膏为主要原料，进一步结合水泥、超细活性掺合料、激发剂、造孔剂等进行复合激发水化反应，形成具有丰富微细连通孔的轻集料体系，同时利用胶结反应将硼、铅具有屏蔽效应的组分进行空间交联，可进一步显著提升对中子射线的屏蔽能力。本发明所述磷石膏集料兼具良好的力学性能、储释水性能和防中子射线性能，可实现磷石膏高价值化利用；且涉及的制备方法简单可控，能耗较低，适合推广应用。
