Anti-radiation self-compacting concrete and preparation method thereof
The invention relates to radiation-proof self-compacting concrete and a preparation method thereof in the technical field of concrete. The concrete is prepared from the following raw material components in parts by weight: 100 to 300 parts of radiation-proof cement, 600 to 900 parts of barite macadam, 50 to 150 parts of szaibelyite, 7 to 18 parts of a high-efficiency water reducing agent, 0.1 to 0.5 part of sodium dioctyl sulfosuccinate, 0.05 to 0.2 part of a silicon resin polyether emulsion, 0.3 to 1 part of a slow-release defoaming agent, 80 to 130 parts of fly ash, 30 to 60 parts of slag and 160 to 250 parts of water. The slow-release defoaming agent is hydrophobic white carbon black coated with starch sodium octenylsuccinate and soluble soybean polysaccharide. By adding the dioctyl sodium sulfosuccinate and the silicon resin polyether emulsion, a large number of stable bubbles are formed in the concrete, and the friction force among raw material particles is reduced, so that the flowability of the concrete is improved, and self-compaction is realized.
本申请涉及混凝土技术领域的一种防辐射自密实混凝土及其制备方法。按重量份计，混凝土的制备原料包括如下组分：防辐射水泥100‑300份、重晶石碎石600‑900份、硼镁石50‑150份、高效减水剂7‑18份、二辛基琥珀酸磺酸钠0.1‑0.5份、硅树脂聚醚乳液0.05‑0.2份、缓释型消泡剂0.3‑1份、粉煤灰80‑130份、矿渣30‑60份和水160‑250份，缓释型消泡剂为由辛烯基琥珀酸淀粉钠和可溶性大豆多糖包覆的疏水型白炭黑。本申请通过添加二辛基琥珀酸磺酸钠与硅树脂聚醚乳液，在混凝土内形成大量稳定气泡，减小原料颗粒之间的摩擦力，从而提升混凝土的流动性，实现自密实。
