Abstract

Изобретение относитс  к строительным материалам, в частности к способам приготовлени  пластифицирующей добавки дл  бетонной смеси, используемых в производстве бетонных и железобетонных изделий. Цель изобретени  - снижение расхода цемента и повышение выносливости бетона при раст жении. Предлагаемый способ включает обработку раствора технического лигносульфоната отходом от травлени  алюминиевых изделий едким натром, с последующим удалением осадка и термообработкой раствора при 95-100°С в течение 10-30 мин при следующем соотношении исходных компонентов на сухие продукты, мас.%: технический лигносульфонат 40-55, едкий натр 10-20; тетрагидроксоалюминат натри  10-20; пентогидроксоалюминат натри  5-10; гидроокись алюмини  10-20 Введение в бетонную смесь предлагаемого пластификатора в количестве 0,2-0,8% от массы цемента позвол ет снизить расход цемента на 15% и повысить выносливость бетона при раст жении в 4 раза по сравнению с известным. 1 табл L ЧЭ ч-со сThe invention relates to building materials, in particular to methods for preparing a plasticizing agent for concrete mixtures used in the manufacture of concrete and reinforced concrete products. The purpose of the invention is to reduce the consumption of cement and increase the endurance of concrete during stretching. The proposed method involves treating a solution of technical lignosulfonate with a waste from pickling aluminum products with caustic soda, followed by removing the precipitate and heat treating the solution at 95-100 ° C for 10-30 minutes in the following ratio of initial components to dry products, wt.%: Technical lignosulfonate 40-55, caustic soda 10-20; sodium tetrahydroxoaluminate 10-20; sodium pentohydroxoaluminate 5-10; aluminum hydroxide 10-20 The introduction of the proposed plasticizer in an amount of 0.2-0.8% by weight of cement reduces the consumption of cement by 15% and increases the endurance of concrete when stretched by 4 times compared with the known. 1 table L CHE h-with with
