Изобретение относитс к составам бсто)ных смесей.The invention relates to compositions of bste mixtures.
Известна бетонна смесь, содержаща минеральное в жущее, заполнитель, воду и латекс СКС-65 в качестве добавки.A concrete mix is known that contains a mineral in the grout, aggregate, water and latex SCS-65 as an additive.
Цель изобретени - повысить термическую трещиностойкость и раст жимость бетона.The purpose of the invention is to increase the thermal crack resistance and extensibility of concrete.
Это достигаетс тем, что в качестве добавки бетонна смесь содержит стнролбутадиеновый латекс с ноложительным зар дов частиц в количестве 0, от веса минерального в жущего.This is achieved by the fact that, as an additive, the concrete mixture contains stnrolbutadiene latex with a positive charge of particles in an amount of 0, by weight of the mineral binder.
Латекс, используемый в качестве добавки в бетоны, имеет положительный зар д частиц полимера и обладает более высокой стабильностью ио отношению к ионам щелоче-земельных металлов, ирисутствующим в цементном тесте и вызывающим коагул цию обычных анионоактивных латексов с отрицательным зар дом частиц.Latex, used as an additive to concrete, has a positive charge of polymer particles and has a higher stability with respect to alkaline earth metal ions, which are present in the cement paste and cause coagulation of ordinary anionic latexes with negative particle charge.
Предлагаемые латексы используютс без дополнительной стабилизации.The proposed latexes are used without additional stabilization.
Синтез такого латекса провод т в присутствии катионоактивных стабилизаторов в кис9The synthesis of such latex is carried out in the presence of cationic stabilizers in acid
лой среде. В качестве стабилизатора ирпмен ют , нанрпмер, триметплалкнламмоннйхлорид . Общее содержание поверхностно-активных веществ в этом латексе равно 4%.environment. As a stabilizer, irpmene, nanrpmer, trimetlphenlaminemonic chloride. The total content of surfactants in this latex is 4%.
Положительно зар женные частнцы нолнмеров значительно лучще распредел ютс во всей массе положительно зар женного цементного теста, не взаимодейству с ипм.The positively charged particles of nolmer are much better distributed throughout the whole mass of positively charged cement dough, I do not interact with ipm.
Латекс ввод т в состав раствора пли бетонион смеси вместе с водой затворенн в коЛ1ПКЧ-ТНГ 0,5--5% от веса минерального в жуHiiM о.Latex is introduced into the composition of the pl or concrete mixture with the water shut at 0.5% -5% of the weight of the mineral in minerals.
