Description
Изобретение относитс к композици м дл пропитки бетонных изделий и конструкций, к которым предъ вл ютс повышенные требовани по их прочности, морозостойкости, водонепроницаемости , коррозионной стойкости, например , дл гидротехнических сооружений, дорожного строительства и др.The invention relates to compositions for the impregnation of concrete products and structures, which are subject to increased requirements for their strength, frost resistance, water resistance, corrosion resistance, for example, for hydraulic structures, road construction, etc.
Известна композици дл пропитки бетонных изделий, включающа водный насыщенный раствор карбоната аммони . Однако процесс пропитки бетона раствором карбоната аммони вл етс самотормоз щимс , так как продукты взаимодействи карбоната аммони с компонентами цементного камн , кольматиру поры и капилл ры поверхностного сло бетона, затрудн ют доступ пронитывающего раствора к внутренним сло м бетона.A known composition for impregnating concrete products, comprising an aqueous saturated solution of ammonium carbonate. However, the process of impregnating the concrete with ammonium carbonate solution is self-braking, since the products of the interaction of ammonium carbonate with the components of cement stone, clogging the pores and capillaries of the surface layer of concrete, make it difficult for the permeating solution to access the internal layers of concrete.
Цель изобретени - повышение прочности и химической стойкости бетонных изделий. Это достигаетс тем, что композици дл пропитки бетонных изделий дополнительно содержит сульфитно-дрожжевую бражку (СДБ) при следующем соотношении компонентов, вес. %:The purpose of the invention is to increase the strength and chemical resistance of concrete products. This is achieved by the fact that the composition for impregnation of concrete products additionally contains a sulphite-yeast mash (SBR) in the following ratio of components, weight. %:
Водный насыщенный раствор карбоната аммони 99,5-99,95Aqueous saturated ammonium carbonate solution 99.5-99.95
Сульфитно-дрожжева бражка0 ,05- 0,5Sulphite yeast brag0, 05- 0,5
Введение в раствор карбоната аммони и поверхностноактивного вещества типа СДБ в указанных количествах существенно повышает эффективность пропитки, так как гидрофилизующа добавка СДБ улучшает смачиваемость бетона пропитывающим составом и благодар снижению поверхностного нат жени способствует проникновению раствора в более мелкие поры, капилл ры и микротрещины бетона, которые кольматируютс продуктами химического взаимодействи между карбонатом аммони и компонентами цементного камн . В этих услови х увеличиваетс не только прочность, но и плотность бетона,The introduction of ammonium carbonate and a surfactant of the type DLB in specified amounts to the solution significantly increases the impregnation efficiency, since the hydrophilizing additive DLI improves the wettability of the concrete with the impregnating composition and, by reducing the surface tension, promotes the penetration of the solution into smaller pores, capillaries and microcracks of the concrete, which collate chemical interaction products between ammonium carbonate and cement stone components. Under these conditions, not only the strength but also the density of the concrete increases,
что способствует повышению его стойкости.which contributes to its durability.
Бетонные издели можно пропитывать погружением в водный насыщенный раствор карбоната аммони с добавкой СДБ, нанесением пропиточной композиции на поверхность издели , подачей пропиточной композиции в технологические пустоты или специальные отверсти , а также комбинацией указанных методов .Concrete products can be impregnated by immersion in an aqueous saturated solution of ammonium carbonate with the addition of DBB, applying the impregnating composition on the surface of the product, feeding the impregnating composition into process voids or special holes, as well as a combination of these methods.
