Method for preparing nano calcium silicate hydrate seed crystal early strength agent from fly ash and application of nano calcium silicate hydrate seed crystal early strength agent
The invention discloses a preparation method for preparing a nano calcium silicate hydrate seed crystal early strength agent by using fly ash and application of the nano calcium silicate hydrate seed crystal early strength agent, the early strength agent comprises the following components in percentage by mass: 3-5% of a silicon source, 5-6% of a calcium source, 34-35% of a sodium hydroxide solution and the balance of water, and the silicon source is fly ash. The preparation method comprises the following steps: adding a silicon source, a calcium source and grinding balls into a sealed grinding tank according to a designed mixing ratio; measuring a specified sodium hydroxide solution, and adding the specified sodium hydroxide solution and boiled water into the grinding tank until the whole grinding tank is filled with the sodium hydroxide solution; wet grinding is conducted at the speed of 600-650 revolutions per minute, standing reaction is conducted for 1 day after grinding is conducted for 1-2 hours, and wet grinding is conducted for 3-5 days. According to the early strength agent, the early strength of a cement-based material is obviously improved, the later strength is slightly reduced, no harmful substance is generated, and the defects of a traditional early strength agent are overcome.
本发明公开了一种利用粉煤灰制备纳米水化硅酸钙晶种早强剂的制备方法及其应用，所述早强剂包括以下质量百分数的组分：硅源3％‑5％、钙源5％‑6％、氢氧化钠溶液34％‑35％，余量为水，所述硅源为粉煤灰。所述制备方法包括以下步骤：将硅源、钙源和研磨球按照设计的配合比加入密封的研磨罐中；量取规定的氢氧化钠溶液，并与煮沸后的水一并加入研磨罐中至充满整个研磨罐；以每分钟600‑650转的速度湿磨，每研磨1‑2小时就静置反应1天，湿磨3‑5天。本发明的早强剂对水泥基材料的早期强度明显提升，后期强度倒缩微小，无有害物质产生，解决了传统早强剂所存在的缺点。
