Description
II
Изобретение относитс к добавкам дл бетонньах смесей и строительных растворов.The invention relates to additives for concrete mixtures and mortars.
Известна комплексна добавка, содержаща сульфат натри , сульфитноспиртовую барду и нитрит-нитрат-хлорид кальци ij ,Known complex additive containing sodium sulfate, sulfite alcohol bard and nitrite-nitrate-calcium chloride ij,
Наиболее близка к предлагаемому изобретению по технической сущности и достигаемому результату . комплексна добавка, содержаща хлорид , нитрит натри и сульфитноспиртовую барду при следующем соотношении компонентов, 8ес.%: (от веса цемента);Closest to the proposed invention to the technical essence and the achieved result. complex additive containing chloride, sodium nitrite and sulfite alcohol bard in the following ratio of components, 8% by weight: (by weight of cement);
Хлорид кальци 1,5Calcium Chloride 1.5
Нитрит натри 0,75 Sodium nitrite 0.75

2 Однако бетон с этими добавками2 However, concrete with these additives
обладает недостаточной прочностью, морозостойкостью и коррозионной стойкостью .has insufficient strength, frost resistance and corrosion resistance.
Целью изобретени вл етс сокращение расхода цемента, повьпиение прочности, морозостойкости и коррозионной стойкости бетона.The aim of the invention is to reduce cement consumption, improve strength, frost resistance and corrosion resistance of concrete.
Это достигаетс тем, что комплексна добавка дл бетонных смесей иThis is achieved in that the complex additive for concrete mixtures and
строительных растворов, состо ща из хлорида, нитрита натри и сульфитно-спиртовой барды, дополнительно содержит сульфат натри , а в качестве хлорида - хлорид кали при следующем соотношении компонентов, вес.%: Хлорид кали 10-40 Нитрит натри 10-40 Сульфитно0 спиртова барда 2-10 Сульфат натри 10-78 Готовили бетонную смесь при следующем соотношении компонентов, вес.ч.: Цемент марки 400350building solutions, consisting of chloride, sodium nitrite and sulphite-alcohol stillage, additionally contains sodium sulphate, and potassium chloride as the chloride in the following ratio of components, wt.%: Potassium chloride 10-40 Sodium nitrite 10-40 Sulfite-alcohol bard 2-10 Sodium sulfate 10-78 Concrete mixture was prepared in the following ratio of components, parts by weight: Cement grade 400350
