Description
Изобретение относитс к составам дл защиты арматуры от коррозии, .примен емым в железобетонных строительных детал х из автоклавных бетонов.This invention relates to compositions for protecting rebar from corrosion, used in reinforced concrete building parts from autoclaved concrete.
Известен состав антикоррозионной мастики дл защиты арматуры от коррозии, состо щий из сланцевого битума и портландцемента в соотношении, например, 1 : 2,5 по весу.The composition of anticorrosive mastic for protecting the reinforcement from corrosion, consisting of shale bitumen and Portland cement in a ratio of, for example, 1: 2.5 by weight, is known.
Однако такой состав имеет слабую степень защиты арматуры от коррозии.However, such a composition has a weak degree of protection of valves against corrosion.
Цель изобретени - повышение защитнь х свойств мастики.The purpose of the invention is to increase the protective properties of mastic.
Это достигаетс тем, что мастика содержит дополнительно сланцевые фенолы в количестве 1-5%.This is achieved by the fact that the mastic contains additionally shale phenols in the amount of 1-5%.
Сланцевые фенолы, введенные в состав мастики , вл ютс антиоксидантами, афеп тствующими старению мастики. Они поглощают кислород, в результате чего депол ризатор неShale phenols incorporated in mastic are antioxidants, which are anti-aging mastic. They absorb oxygen, causing the depolarizer not to

Результаты проведенных испытаний показали , что если известный состав способен поглощать .кислород в количестве 0,12 мг/г час, то у предлагаемого состава способность ноглоИ1 ,ени кислорода повышаетс до 3,33 мг/г час.The results of the tests showed that if a known compound is capable of absorbing oxygen in an amount of 0.12 mg / g hour, then the composition of the proposed composition of oxygen can increase to 3.33 mg / g hour.
Скорость коррозии арматуры, цокрыто1 предлагаемой мастикой, умепьн аетс в 4 раза но сравнению с известным составом.The corrosion rate of the reinforcement, the base of the proposed mastic, is 4 times less compared with the known composition.
Предмет изобретени Subject invention
Антикоррозионна мастика, например, дл защиты арматуры в чеистых бетонах автоклавного твердени , включающа битум и портландцемент, отличающа с тем, что, с целью повышени защитных свойств мастики, она содержит дополнительно сланцевые фенолы в количестве 1-5%.Anticorrosive mastic, for example, for the protection of reinforcement in cellular autoclaved concrete, including bitumen and portland cement, characterized in that, in order to increase the protective properties of the mastic, it additionally contains shale phenols in an amount of 1-5%.
