The invention provides an inorganic-organic framework material for internal curing of concrete and a preparation method of the inorganic-organic framework material. The inorganic-organic framework material is prepared by carrying out polymerization reaction on the following raw materials in parts by weight in water: 20-40 parts of a super absorbent resin monomer, 40-60 parts of a nanoscale cement hydration product, 1.5-3 parts of a cross-linking agent, 1.5-3 parts of an initiator and 10-20 parts of a catalyst. The inorganic-organic framework material prepared by the invention is high in water absorption rate, slows down in water release rate, and can significantly improve the damage of introduction of an internal curing agent to the mechanical properties of concrete.
本发明提供了一种用于混凝土内养护的无机‑有机骨架材料及其制备方法，所述无机‑有机骨架材料由以下重量份的原料在水中聚合反应制备得到：高吸水树脂单体20‑40份、纳米尺度水泥水化产物40‑60份、交联剂1.5‑3份、引发剂1.5‑3份、催化剂10‑20份。本发明制得的无机‑有机骨架材料吸水倍率高，释水速率变缓，可显著改善内养护剂引入对混凝土力学性能的损伤。
