Organic-inorganic composite alkali activator for alkali-activated cementing materials and preparation method of organic-inorganic composite alkali activator
The invention relates to an organic-inorganic composite alkali activator for alkali-activated cementing materials and a preparation method of the organic-inorganic composite alkali activator. The composite alkali activator comprises the following raw material components in parts by mass: 285-300 parts of sodium carbonate, 71-75 parts of sodium sulfate, 21-25 parts of semi-hydrated gypsum, 7-15 parts of light stone powder, 275-300 parts of an organic alkali solution and 316-335 parts of water. The organic-inorganic composite alkali activator provided by the invention has relatively low alkalinity, does not cause harm to a human body and the environment, has a quite good excitation effect through a synergistic effect of inorganic alkali excitation and promotion of mineral phase dissolution by organic matters, meets the strength standard of P.O 52.5, and potential safety hazards caused by alkali-aggregate reaction due to overhigh alkalinity are avoided, and the organic-inorganic composite alkali activator is good in stability and low in cost.
本发明涉及一种用于碱激发胶凝材料的有机‑无机复合碱激发剂及其制备方法，所述复合碱激发剂原料组分及其质量份配比如下：碳酸钠285‑300份，硫酸钠71‑75份，半水石膏21‑25份，轻质石粉7‑15份，有机碱溶液275‑300份，水316‑335份。本发明提供的有机‑无机复合碱激发剂具有较低的碱度，不会对人体和环境造成危害，通过无机碱激发和有机物促进矿物相溶出的协同作用，具有很好的激发效果，在满足P.O 52.5的强度标准的同时，也不会因为碱度过高发生碱集料反应产生安全隐患，且稳定性好，成本低。
