Preparation method of modified nano calcium hydroxide and application of modified nano calcium hydroxide in prefabricated parts
The invention discloses a preparation method of modified nano calcium hydroxide and application of the modified nano calcium hydroxide in prefabricated parts, and belongs to the technical field of concrete admixture materials. The modified nano calcium hydroxide is prepared, the average particle size of the modified nano calcium hydroxide is 50-90 nm, and after the modified nano calcium hydroxide is doped into cement, the effect of adjusting alkalinity can be achieved, and more importantly, the crystal nucleus effect can be provided for cement hydration. And the prepared nano calcium hydroxide has good stability, can quickly promote the early strength of ordinary Portland cement, and has no influence on the later strength.
本发明公开一种改性纳米氢氧化钙的制备方法及其在预制构件中的应用，属于混凝土外加剂材料技术领域。本发明制备得到一种改性的纳米氢氧化钙，经过改性的纳米氢氧化钙，平均粒径为50‑90nm，在掺入水泥中后，不仅仅可以起到调节碱度的作用，更重要的是可为水泥水化提供晶核作用。并且本发明制备得到的纳米氢氧化钙，稳定性好，能够快速促进普通硅酸盐水泥早期强度，且对后期强度无影响。
