The invention relates to the technical field of concrete admixtures, in particular to a solid concrete water reducer and a manufacturing method thereof. Modified beta-cyclodextrin obtained after beta-cyclodextrin is subjected to pretreatment, pre-modification, modification and other steps serves as a macromonomer to directly participate in a free radical polymerization reaction of a polycarboxylic acid water reducing agent, and the polycarboxylic acid solid concrete water reducing agent containing beta-cyclodextrin is prepared. The solid concrete water reducing agent prepared by the technical scheme is simple in process, small in doping amount, good in dispersion effect, excellent in water reducing performance and easy to store and transport, and the production cost is reduced.
本发明涉及混凝土外加剂技术领域，具体涉及一种固态混凝土减水剂及其制造方法。本发明将β‑环糊精经过预处理、预改性、改性等步骤处理后得到的改性β‑环糊精作为大分子单体直接参与聚羧酸减水剂的自由基聚合反应中，制备了含有β‑环糊精的聚羧酸固态混凝土减水剂。通过本发明技术方案制备的固态混凝土减水剂，工艺简单，掺用量少，分散效果好，减水性能优异，易于存放和运输，降低了生产成本。
