Anti-radiation concrete and preparation method thereof
The invention relates to the field of concrete preparation, and particularly discloses anti-radiation concrete and a preparation method thereof. The anti-radiation concrete is prepared from the following raw materials in parts by weight: 100 to 130 parts of cement, 35 to 50 parts of fly ash, 30 to 40 parts of mineral powder, 100 to 150 parts of coarse aggregate, 70 to 100 parts of fine aggregate, 10 to 20 parts of metal fiber, 15 to 25 parts of composite filler, 65 to 72 parts of cold water, 1 to 2 parts of retarder and 2.2 to 4.0 parts of water reducing agent. The preparation method comprises the following steps: weighing the cement, the fly ash, the mineral powder, the metal fibers and the composite filler, and uniformly mixing and stirring to obtain a primary mixture; weighing coarse aggregate and fine aggregate, mixing and stirring uniformly, and then mixing and stirring uniformly with the primary mixture to obtain a mixture; weighing the mixture, cold water, a water reducing agent and a retarder, and uniformly mixing and stirring to obtain a mixed material; and pouring and curing the mixed material to obtain the anti-radiation concrete. The finished product has the advantages of being not prone to cracking and high in strength.
本申请涉及混凝土制备领域，具体公开了一种抗辐射混凝土及其制备方法；抗辐射混凝土包含以下重量份的原料制成：水泥100‑130份、粉煤灰35‑50份、矿粉30‑40份、粗骨料100‑150份、细骨料70‑100份、金属纤维10‑20份、复合填料15‑25份、冷水65‑72份、缓凝剂1‑2份、减水剂2.2‑4.0份；其制备方法为：称取水泥、粉煤灰、矿粉、金属纤维、复合填料混合搅拌均匀，制得初混料；称取粗骨料、细骨料混合搅拌均匀，然后与初混料混合搅拌均匀制得，混合料；称取混合料、冷水、减水剂、缓凝剂混合搅拌均匀，制得拌和料；拌和料经浇筑、养护，制得抗辐射混凝土；使成品具有不易开裂且强度较高的优点。
