Radiation-proof high-strength concrete and preparation method thereof
The invention relates to the technical field of concrete, and provides radiation-proof high-strength concrete and a preparation method thereof. The concrete is prepared from the following components in parts by weight: 300 to 340 parts of cement, 150 to 160 parts of water, 1000 to 1100 parts of barite sand, 1400 to 1600 parts of gravel, 60 to 80 parts of borocalcite powder, 8 to 10 parts of polycarboxylate superplasticizer and 60 to 80 parts of modifier. The modifier contains an adamantane structure, a borate structure and carboxyl. The concrete with good gamma ray and neutron ray shielding capability is prepared by the method disclosed by the invention, and the mechanical strength of the radiation-proof concrete can be improved by utilizing the high hardness of an adamantane structure and the complexing capability of carboxyl on Ca < 2 + >.
本发明涉及混凝土的技术领域，提供了一种防辐射的高强度混凝土及其制备方法。按重量份计，该混凝土的组分包括水泥300‑340份、水150‑160份、重晶石砂1000‑1100份、碎石1400‑1600份、硼钙石粉60‑80份、聚羧酸减水剂8‑10份、改性剂60‑80份。所述改性剂中含有金刚烷结构、硼酸酯结构及羧基。本发明的方法制得了具有良好γ射线和中子射线屏蔽能力的混凝土，而且，利用金刚烷结构的高硬度和羧基对Ca2+的络合能力，可提高防辐射混凝土的力学强度。
