Auxiliary agent for improving side effects of fly ash as well as preparation method and application of auxiliary agent

The invention provides a fly ash side effect improving aid and a preparation method and application thereof, and relates to the technical field of fly ash aids. The auxiliary agent for improving the side effects of the fly ash is prepared from the following raw materials in parts by weight: 200 to 400 parts of polyoxyethylene ether macromonomers, 10 to 30 parts of unsaturated acid monomers, 5 to 16 parts of sulfonic acid adsorbents, 3 to 15 parts of amine hydration accelerators, 1 to 4 parts of oxidizing agents, 0.5 to 2 parts of reducing agents and 1 to 4 parts of chain transfer agents. The fly ash side effect improving auxiliary agent can effectively improve the problems of abnormal black ash secretion and the like of mortar or a concrete mixture prepared from fly ash, improves the workability of the concrete mixture, and ensures the construction performance of the concrete mixture. 本发明提供一种粉煤灰副作用改善助剂及其制备方法和应用，涉及粉煤灰助剂技术领域。本发明的粉煤灰副作用改善助剂包括以下重量份的原料：聚氧乙烯醚类大分子单体200～400份，不饱和酸单体10～30份，磺酸类吸附剂5～16份，胺类水化促进剂3～15份，氧化剂1
