Изобретение относитс к способам -нридаНИ1Я водостойкости строительным конструкци м .FIELD OF THE INVENTION The invention relates to methods for the non-inferior water resistance of building structures.
Известен способ придани водостойкости строительным конструкци м путем илъекцировани смеси растворимого стекла с железистой солью в поры издели .There is a known method of imparting water resistance to building structures by injecting a mixture of soluble glass with ferrous salt into the pores of the product.
Цель изобретени - повысить срок службы изделий.The purpose of the invention is to increase the service life of the products.
Это достигаетс тем, что водный раствор железистой соли нагнетают в массу бетона в течение 2-7 суток, а затем поверхность издели обрабатывают растворимым стеклом с модулем 2,5-2,7.This is achieved by pumping an aqueous solution of ferrous salt into the mass of concrete for 2-7 days, and then the surface of the product is treated with soluble glass with a module of 2.5-2.7.
Соли многовалентных металлов, например железистые, фильтру сь совместно с водой, взаимодействуют с карбонатами, образу нерастворимый осадок гидроокиси металлов и закупоривают поры и трещины, понижа водопроницаемость бетона. Используют слабый раствор солей многовалентных металлов 0,05-0,2%-1ной концентрации. Дл интенсификации процесса в раствор предварительно ввод т известковое молоко.Polyvalent metal salts, such as ferrous metals, co-filter with water, interact with carbonates to form an insoluble precipitate of metal hydroxide and clog pores and cracks, reducing the permeability of concrete. Use a weak solution of the salts of polyvalent metals 0.05-0.2% -1-1 concentration. To intensify the process, lime milk is preliminarily introduced into the solution.
В результате кольматажа коэффициент фильтрации бетона может быть снижен с 0,2-0,5 до 10 - MJсутки. Расход железистых солей составл ет 0,5-1,0 кг1м. Дл As a result of mudding, the filtration coefficient of concrete can be reduced from 0.2-0.5 to 10 - MJ days. The consumption of ferrous salts is 0.5-1.0 kg1 m. For
дальнейшей обработки бетонной поверхности используют слабый раствор жидкого натриевого стекла с модулем 2,5-2,7 из расчета 0,05-0,15 кг1м. Предлагаемый способ может быть использован в промышленном, транспортном и шахтном строительстве.further processing of the concrete surface using a weak solution of liquid sodium glass with a module of 2.5-2.7 at the rate of 0.05-0.15 kg1m. The proposed method can be used in industrial, transport and mining construction.
