Multi-density-grade pumping anti-radiation concrete
The invention discloses multi-density-grade pumping radiation-proof concrete, which is prepared from the following ingredients in parts by weight: 200 to 250 parts of cement, 50 to 70 parts of coal ash, 100 to 150 parts of barite powder, 100 to 150 parts of heavy metal powder, 10 to 20 parts of radiation-proof additives, 1600 to 1650 parts of barite macadam, 1400 to 1450 parts of barite sand, 160 to 170 parts of water and 5.0 to 5.5 parts of additives. The barite is adopted as the aggregate, the fly ash is added, so that the workability is better, the pumping construction requirement can be met, and the heavy metal powder is added, so that the compressive strength of the radiation-proof concrete is enhanced, and the requirements of radiation-proof concrete with different apparent densities can be met; by adding the lithium-based anti-radiation additive, the compactness of the concrete can be improved, the penetration strength of neutron current is effectively weakened, and the shielding capability of the anti-radiation concrete is remarkably improved.
本发明公开了一种多密度等级泵送防辐射混凝土，组成按重量份数计如下：水泥200‑250份，粉煤灰50‑70份，重晶石粉100‑150份，重金属粉100‑150份，防辐射添加剂10‑20份，重晶石碎石1600‑1650份，重晶石砂1400‑1450份，水160‑170份，外加剂5.0‑5.5份；本发明采用重晶石作为骨料，加入粉煤灰能使其和易性较好，能够满足泵送施工的要求，加入重金属粉，有利于增强防辐射混凝土的抗压强度，并能够满足对于不同表观密度防辐射混凝土的需求；加入锂基防辐射添加剂，能改善混凝土密实度，有效减弱中子流的穿透强度，显著改善防辐射混凝土的屏蔽能力。
