о Изобретение относитс к составам неорганических добавок дл бетонных смесей и цементных растворов. Известна добавка в бетонную смес сернокислого алюмини A1(SOij), и (NaOH) щелочи l . Однако эта добавка позвол ет йолучить бетон с -недостаточно высок ми показател ми прочности il. Наиболее близкой к предлагаемой по технической сущности и достигаемому эффекту вл етс добавка в бетонную смесь сульфата железа и окисного соединени щелочноземельного металла - хлорной извести 2J. Известна добавка ускор ет твердение бетона, однако прочность бето на в возрасте 28 суток недостаточно высока. Целью изобретени вл етс повышение прочности бетона. Поставленна цель достигаетс тем, что комплексна добавка в бетонную смесь, включающа сульфат железа и окисное соединение щелочно зс|мельного металла, содержит в качестве последнего гидроокись натри , при соотношении компонентов добавки, мае.%: Сульфат селеза 57,14-60,00 Гидроокись натри 40,00-42,86 Эта добавка вводитс в бетоннзто смесь в количестве 5,5-8,4% от масс цемента с водой затворени . Приготовление бетонной смеси осуществл ют по общеприн той технологии . При испытани х бетонной смеси используют портландцемент М-400, кварцевый песок, гранитный щебень и воду при следующем соотношении компонентов, мас.% (контрольный состав): Портландцемент 15,4 Кварцевый песок25,7 Гранитный щебень В бетонную смесь с водой при затворении ввод т известную (FeS04 + CaOCI) и предлагаемую (FeSO j+NaOH) добавки в соответствующем количестве от массы цемента и формуют из нее кубики размером 100 100 мм. Подвижность бетонной смеси по осадке конуса составл ет 5 см. Тепловлажностную обработку провод т по режиму 2+6+естественный сброс температуры (температура изотермической выдержки 95с).. Качественный и количественньй . составы добавок и результаты испытаний бетона приведены в таблице. Таким образом, применение предлагаемой добавки позвол ет в 28 суточном возрасте на .30-35% повысить прочность по сравнению с контрольным составом и на 15-16% по сравнению с составом известным. При сохранении прочности на исходном уровне можно сократить на 20% расход цемента.o The invention relates to compositions of inorganic additives for concrete mixtures and cement mortars. Known additive in the concrete mixture of aluminum sulphate A1 (SOij), and (NaOH) alkali l. However, this additive allows for concrete with insufficiently high strength indicators il. Closest to the proposed technical essence and the achieved effect is the addition to the concrete mixture of iron sulfate and oxide compound of an alkaline earth metal - bleach 2J. The known additive accelerates the hardening of concrete, however, the strength of concrete at the age of 28 days is not high enough. The aim of the invention is to increase the strength of concrete. The goal is achieved by the fact that the complex additive in a concrete mix, including iron sulfate and an oxide compound of an alkaline metal, contains sodium hydroxide as the latter, with a ratio of components of the additive, may.%: Selenium sulfate 57.14-60.00 Hydroxide sodium 40.00-42.86 This additive is introduced into the concrete mixture in the amount of 5.5-8.4% by weight of cement with mixing water. The preparation of the concrete mixture is carried out according to conventional technology. When testing concrete mixers, Portland cement M-400, quartz sand, granite crushed stone and water are used in the following ratio of components, wt.% (Reference composition): Portland cement 15.4 Quartz sand 25.7 Granite crushed stone is introduced into the concrete mix with water during mixing known (FeS04 + CaOCI) and the proposed (FeSO j + NaOH) additives in an appropriate amount by weight of cement and molded from it cubes with a size of 100 100 mm. The mobility of the concrete mixture in the cone draft is 5 cm. The heat and moisture treatment is carried out according to the mode 2 + 6 + natural temperature drop (isothermal holding temperature 95s) .. Qualitative and quantitative. The compositions of additives and the results of tests of concrete are given in the table. Thus, the use of the proposed additive makes it possible to increase the strength by 28–30% in comparison with the control composition and by 15–16% in comparison with the composition known. While maintaining strength at the original level, cement consumption can be reduced by 20%.
