Description
Изобретение относитс к составам добавок дл бетонных смесей, используемых S строительстве дл изготовлени железобетонных конструкций.The invention relates to additive compositions for concrete mixtures used in construction for the manufacture of reinforced concrete structures.
Известна комплексна добавка в бетонную смесь, включающа фосфорнокислый натрий и аммоний, железо сернокислое 1 .A complex additive in a concrete mix, including sodium and ammonium phosphate, iron sulfate 1 is known.
Наиболее близкой к предлагаемой по технической сущности и достигаемому результату вл етс комплексна добавка 2, включающа , %: нитрит натри 66-75 фосфорнокислый натрий 25-34.Closest to the proposed technical essence and the achieved result is a complex additive 2, comprising,%: sodium nitrite 66-75 sodium phosphate 25-34.
Добавка защищает арматуру от коррозии в бетоне при содержании в ней 2,95% ионов хлора от массы в жущего.The additive protects the reinforcement from corrosion in concrete with a content of 2.95% of chlorine ions by weight of the substance.
Недостатком таких добавок в бетонную смесь вл етс низка коррозионна стойкость арматуры в бетоне.The disadvantage of such additives in the concrete mix is the low corrosion resistance of the reinforcement in the concrete.
: Цель изобретени - повышение коррозионной стойкости арматуры.The purpose of the invention is to increase the corrosion resistance of the reinforcement.
5 Поставленна цель достигаетс тем,5 The goal is achieved by
что I комплексна добавка,включающа - фосфорнокислый натрий и нитрит натри , содержит указанные компоненты при следующем соотношении, мас.% )Q Фосфорнокислый натрий 66-75 Нитрит натри 25-34that I complex additive, including sodium phosphate and sodium nitrite, contains these components in the following ratio, wt.%) Q Sodium phosphate 66-75 Sodium nitrite 25-34
Добавку ввод т в бетонную смесь с водой затворени в количестве 2,8-4% от массы портландцемента.The additive is introduced into the concrete mix with mixing water in an amount of 2.8-4% by weight of portland cement.
