Medium-and-low-radioactivity nuclear waste curing and packaging material
The invention relates to the technical field of nuclear physics, nuclear engineering and radioactive contamination treatment materials, and discloses a medium-low-radioactivity nuclear waste curing and packaging material which comprises a component A and a component B. The component A comprises the following raw materials in parts by weight: 270-480 parts of cement, 330-600 parts of 0.16-1.25 mm barite machine-made sand, 50-200 parts of ground mineral powder, 50-150 parts of silica fume and 10-50 parts of floating beads. And the component B comprises the following raw materials in parts by weight: 9-12mm of copper-plated steel fibers (with the diameter of 0.15-0.20 mm), 1-3 parts of a water reducing agent, 1-3 parts of a water-retaining agent and 1-3 parts of a defoaming agent. The medium-low-radioactivity nuclear waste curing and packaging material is prepared from the cement, the barite machine-made sand, the ground mineral powder, the silica fume, the floating beads, the water reducing agent, the water-retaining agent, the defoaming agent and the copper-plated steel fibers, and has ultra-high performance of UHPC (Ultra High Performance Concrete) which can be used for pumping construction and normal-temperature maintenance and has ultra-high strength and excellent durability.
本发明涉及核物理、核工程、处理放射性污染材料技术领域，且公开了一种中低放射性核废料固化与封装材料，包括A组份和B组份，所述A组份包括以下重量份数配比的原料：水泥270‑480份、0.16‑1.25mm重晶石机制砂330‑600份、磨细矿粉50‑200份，硅灰50‑150份，漂珠10‑50份，减水剂1‑3份，保水剂1‑3份，消泡剂1‑3份，所述B组份包括以下重量份数配比的原料：9‑12mm镀铜钢纤维(直径0.15‑0.20mm)。该中低放射性核废料固化与封装材料，通过采用水泥、重晶石机制砂、磨细矿粉、硅灰、漂珠、减水剂、保水剂、消泡剂和镀铜钢纤维所制成的中低放射性核废料固化与封装材料，具有可泵送施工、常温养护的超高强度、优异耐久性的UHPC超高性能。
