Abstract
Изобретение относитс к технологии производства бетонной смеси и направлено на повышение ее подвижносмость бетонной смеси. Способ приготовлени бетонной смеси заключаетс в перемешивании цемента, заполнител , воды затворени и 0,5-0,6% от-массы цемента пластифицирующей добавки. Пластифицирующую добавку готов т путем смешивани водного раствора сульфитно-дрожжевой бражки с каменноугольной золой и гашеной известью при их соотношении 1-3:1:1-3 в пересчете на сухое вещество в течение 15-40 мин с последующим удалением твердого осадка. 2 табл. ГС ;о со 4 слThe invention relates to a technology for the production of a concrete mix and is aimed at increasing its mobility of the concrete mix. The method of preparing a concrete mix consists of mixing the cement, aggregate, mixing water and 0.5-0.6% by weight of the cement plasticizer. The plasticizing additive is prepared by mixing an aqueous solution of a sulfite-yeast brew with coal ash and slaked lime at a ratio of 1-3: 1: 1-3, calculated on the dry matter, for 15-40 minutes, followed by removal of the solid precipitate. 2 tab.

Description
Изобретение относитс к строительным материала, а именно к технологии приготовлени бетонной смеси с пластифицирующей добавкой на основе лиг- носульфонатов.The invention relates to a building material, in particular to the technology of preparing a concrete mix with a plasticizer based on ligosulfonates.
Цель изобретени - повьшение подвижности бетонной смеси, а также ее удешевлени .The purpose of the invention is to increase the mobility of the concrete mix, as well as reduce its cost.
Бетонную смеет готов т следующим образом. Сульфитно-дрожжевую бражку (СДБ) в виде 10-20%-ного водного раствора смешивают с каменноугольной золой и гашеной известью в течение 15-40 мин в лопастном смесителе принудительного действи , затем отдел ют жидкую фазу от твердой фильтрованием , центрифугированием или другим способом с последующим удалением твердого осадка. Приготовленную таким образом пластифицирующую добавку ввод т в бетонную смесь следующего состава:- цемент : песок : щебень 1:1,8:3,5 при водоцементном отношении В/Ц 0,5, Компоненты бетонной смеси перемешивают до однородного состо ни .Concrete dares are prepared as follows. The sulphite-yeast brew (MDR) in the form of a 10-20% aqueous solution is mixed with coal ash and hydrated lime for 15-40 minutes in a paddle mixer of forced action, then the liquid phase is separated from the solid by filtration, centrifugation or another method subsequent removal of solid sediment. The plasticizing agent prepared in this way is introduced into the concrete mixture of the following composition: - cement: sand: crushed stone 1: 1.8: 3.5 with a water / cement ratio of 0.5 / C. The components of the concrete mix are mixed until uniform.
