Preparation method of environment-friendly and high-performance radiation-proof shielding concrete and product thereof
The invention discloses a preparation method of environment-friendly and high-performance anti-radiation shielding concrete. The preparation method comprises the following steps: crushing and ball-milling waste cathode ray tube (CRT) glass into CRT glass powder fine aggregate; the waste CRT glass powder fine aggregate is soaked in a chemical packaging solution for surface strengthening treatment; mixing the surface-strengthened waste CRT glass powder fine aggregate, river sand fine aggregate, crushed stone coarse aggregate, a cementing material, graphene, water and a high-efficiency water reducing agent to obtain newly-mixed radiation-proof concrete; after the freshly mixed radiation-proof concrete is demolded, surface densification treatment is performed in a carbon dioxide environment, and the environment-friendly and high-performance CRT glass radiation-proof shielding concrete is prepared. According to the invention, resource recycling of wastes is realized, and the prepared anti-radiation shielding concrete has better working performance, mechanical property, radiation shielding effect and lower permeability than traditional anti-radiation shielding concrete, has wide application field, and can generate good technical, economic, social and environmental benefits.
本发明公开了一种环境友好型、高性能防辐射屏蔽混凝土的制备方法，将废弃阴极射线管（CRT）玻璃粉碎球磨成CRT玻璃粉细骨料；废弃CRT玻璃粉细骨料浸泡在化学封装溶液中进行表面强化处理；表面强化处理过的废弃CRT玻璃粉细骨料、河砂细骨料、碎石粗骨料、胶凝材料、石墨稀、水、高效减水剂混合得新拌防辐射混凝土；新拌防辐射混凝土脱模后，在二氧化碳环境中进行表面致密化处理，制备出环境友好型、高性能的CRT玻璃防辐射屏蔽混凝土。本发明实现了废弃物资源化循环再生利用，制备的防辐射屏蔽混凝土具有比传统防辐射屏蔽混凝土更好的工作性能、力学性能、辐射屏蔽效果和更低渗透性，具有广阔应用领域，能产生良好技术、经济、社会和环保效益。
