Description
Изобретение относитс к промышленности строительных материалов. Известен способ приготовлени чеистобетонной смеси, заключающийс в перемешивании компонентов с введением поверхностно- 5 активных веш,еств и аэрировании. Поверхностно-активные вешества, вводимые в смесь при ее затворении, распредел ютс по всему объему смеси, т. е. отлагаютс как на внутренней поверхности газовых пор, так и 10 внутри межпоровых перегородок, что ухудшает прочностные характеристики последних. Предлагаемый способ позвол ет повысить качество чеистобетонной смеси, а также сократить расход поверхностно-активных ве- 15 ществ. Достигаетс это тем, что поверхностноактивные веп;ества ввод т в процессе аэрации в смеси с аэрируюшим газом. Прил1ер. Бетонную смесь подают на аэратор и в нее через перфорированный эле- 20 мент нагнетают вместе с воздухом поверхностно-активные вещества, которые можно использовать в виде раствора, аэрозол , пены или сухого порошка. Расход ПАВ составл ет 0,05-0,1% от веса цемента. Поризаци на аэраторе длитс от 1 до 120 сек., после чего чеистобетонна смесь подаетс в формы. Предмет изобретени Способ приготовлени чеистобетонной смеси , заключающийс в перемешивании компонентов с введением поверхностно-активных веществ и аэрировании, отличающийс тем, что, с целью повышени качества чеистобенной смеси и сокращени расхода поверхностно-активных веществ, последние ввод т в процессе аэрировани в смеси с аэрирующим газом.This invention relates to the building materials industry. There is a known method of preparing a concrete mixture, which consists in mixing the components with the introduction of surface active substances, and aeration. Surface-active substances introduced into the mixture at its mixing are distributed over the entire volume of the mixture, i.e., they deposit on both the inner surface of the gas pores and 10 inside the interpore partitions, which deteriorates the strength characteristics of the latter. The proposed method allows to improve the quality of the concrete mixture, as well as reduce the consumption of surface-active substances. This is achieved by the fact that surfactants are introduced in the process of aeration in a mixture with aerated gas. Enclosed The concrete mixture is fed to the aerator and, through a perforated element, the surface-active substances are injected together with air into the aerator, which can be used in the form of a solution, aerosol, foam, or dry powder. The surfactant consumption is 0.05-0.1% by weight of cement. Porisation on the aerator lasts from 1 to 120 seconds, after which the cellular concrete mixture is fed into the forms. The subject of the invention is a method of preparing a concrete mixture, consisting in mixing components with the introduction of surfactants and aeration, characterized in that, in order to improve the quality of cellular mixture and reduce the consumption of surfactants, the latter are introduced in the process of aeration in a mixture with aerating gas .
